in a 1 litre lance a good guideline is...
500ml product to 500ml water = 4% pir
250ml product to 750ml water = 2% pir
125ml product to 875ml water = 1% pir
Ratio 500 to 500 IS 100%
Big mess with the numbers today 🤔😂
@@gala2314 wrong
@@gj3045 lets make the things clean and clear 500:500×100=???%
@@gala2314 its not the amount in the bottle you helmet. The amount that hits the panel once it mixes with the water flowing through the hose.
@@gj3045 Well, but I don't understand what's the point to do all this so complicated when considering the BH the amount of 250 ml is for 1lt foam lanze .One could see if to lessen it or not 🤔
This is too complicated for me. I just bang some into the bottle,throw in some water and bang it on the car! Job done
exactly my point u hit the nail
This comment is Godlike.. 🙇♂️
exactly How do they expect in nowadays fast pace life to start measuring and calculating etc... most of other manufacturers like Carpro will tell you the exact mixing ratio and off you go
The math is easier if you multiply.
Take what you measured (12000ml) and multiply with 0,04 for 4% or 0,01 for 1% PIR.
In your case:
12000ml*0,04=480ml
12000ml*0,01=120ml
You can do it your way, but I think it gets confusing.
Thank you for making a video how to do it, makes life a lot easier when you know how to measure it properly :D
How do you measure when a product says 1:10 and not % ?
So 1:10 is 10% but your pressure washer will dilute this differently depending on which machine you have so how much product would you need if your machine is 12,000
12,000*0.10 =1200ml 😳 my bottle is only 1000ml
In this case (8 below right? 😊) it is how much you put in a lance. It has nothing to do with PIR, the manufacturer made it easy for user. You can make a same mix as for Autofoam, and see what happens when it has the same PIR.
This is the best way to calculate it
That's a lot of product to use I would have thought John would have realised this and then calculated the cost per use. This video needs an addendum.
For those still struggling to grasp the mathematics, I found this on Bilt Hambers website that explains it in simple terms: Fill up the detergent bottle or reservoir with exactly one litre of water. Take a large bucket or container and discharge the lance into this until the detergent bottle is empty. Measure the total amount of water collected, and multiply this number by 0.04. This is how much auto-foam you need to use in your detergent bottle or reservoir for the correct concentration. When you have measured the auto-foam into the bottle or reservoir, make this up to 1ltr with water. This method will create the correct concentration of auto-foam discharging from the lance, as this depends on the rate at which the reservoir is emptied during use.
That’s how I do it and it appears to work very well.
So assuming I had the same pw, and filled the bucket to 12l, then would I be using 480ml product?
I used 1 part snow foam to 9 parts water in a litre lance, ie 100ml of product to 900ml of water & seemed to work well.
Just tried this with temp pressure washer i have (karcher k2) 26 litres of water so over 1 litre of product required. Think ill wait until my new pressure washer arrives and try again
Got to 18 litres and still had 3 quarters left in canister so I gave up
It turns out I've been using it at about 1% all this time. I used a 4% solution on my wife's FILTHY Skoda Octavia earlier and I was stunned by the difference in results using the higher concentration!
Thanks Jon.
I just figured out an easy and accurate way to calculate PIR.
Dilution on the lance bottle: 1:7
Dilution from the hose water when mixing with the lance bottle: 1:11
Final dilution easy calc: (7 x 11) + 7 + 11 = 95
so 1:95 is the impact dilution, which is equivalent to a 1,04% PIR
It works to all dilutions, for example:
Dilution on the lance bottle: 1:1
Dilution from the hose water when mixing with the lance bottle: 1:11
Final dilution easy calc: (1 x 11) + 1 + 11 = 23
so 1:23 is the impact dilution, which is equivalent to a 4,17% PIR
Maybe someone already had reach this conclusion before, but I figured it out by myself and I'm glad to share it with John and the Forensinc Detailing Channel and it's followers!
When i worked this out for me setup i filled the bucket until 500ml had gone from the lance bottle then doubled it. Just saves a bit of time
I worked this out a while ago. If you follow BH 4% PIR it becomes quite an expensive snow foam!
I now tend to try and judge how much I use depending on how dirty the car is.
Mega dirty = big splash of product.
Lightly dirty = little splash of product.
Should be on the main channel! I simply put in 50ml BHAF to about 300ml water and that's enough for one car. I arrived at this through trial and error so it's nice to see the proper way of calculating it!
Love the fact that UA-cam autotext had John describing the "penile impact ratio"!
I always use 100ml of BH to 900ml of water and it's been fine, might up it to 250ml of BH in the winter though and keep it at 100ml in the summer
I'm the same, I used 100ml P and 900ml W but I'm very tempted to up the ratio especially in winter to allow for more regular contactless washes.
For the measurement accuracy, 1L of water is almost exactly 1Kg in weight so if you haven't got a huge bucket with a scale on it you can use your standard large wash bucket, put it on some bathroom scales, zero the scales, perform this test then weigh the bucket of water and convert the resulting kg to litres. In this video the bucket containing 12 litres would be 12 kilograms in weight. *Disclaimer*: Not my discovery, I saw it (or read it) on internet travels - I can't recall where sadly, but thought I'd post it here as it stuck in my head and it might help newbies like me who are juggling the numbers!
Huge thanks to Jon for his videos. Have learned so much over the last few weeks...!
Science and serenading. The full package today.
Cheers for making this video, saves newbies like me thinking the 1:100 is in the lance 😂
You'd have worked out pretty quickly that it wasn't enough when you didn't get much foam 🤣🤣🤣
Just watched this vid again some 12 months later to remind myself of the ratios! Epic vid again John 👍👍👍👍
Fill your snow foam bottle with exactly 1L of water. Measure this as it must be exact.
2. Connect your foam lance up and make sure the foam nozzle is turned to full foam output (Usually all the way to -).
3. Grab a large container, I used my 20L wash bucket and spray the foam lance into the bucket until the 1L bottle is empty. Add a little food dye to the water within the bottle if your struggling to see the water level.
4. Measure the total amount of water contained within the bucket. I done this by scooping the water out in my measuring beakers.
5. Once you have your total volume (mines is 12.76L), simply multiply this figure by 0.04. This tells you how much auto-foam needs to be used to achieve the 4% PIR.
By doing the above calculation I ended up with a figure of 510ml. I need to use 510ml of auto-foam to 490ml water in my 1L snow foam bottle to achieve the 4% PIR. 510ml of auto-foam was added to the foam bottle using my measuring beakers for an exact measurement.
Bit easier way thanks to detailing world review of autofoam
Good review that 😉🤣
Copy and pasted from a post made in 2017 on detailingworld forum
How do you measure when a product says 1:10 and not % ?
So 1:10 is 10% but your pressure washer will dilute this differently depending on which machine you have so how much product would you need if your machine is 12.76L
@@noeking9095 1:10 isn't 10%, 1:9 is. With regards to your question really not sure what you are asking? Typically if they are stating 10:1 as the dilution that will be in the foam bottle & not the lance.
@@BrianW1612 Step 4 can be made easier by simply weighing the bucket of watet, 1kg = 1 litre
Great video.I absolutely hate it when manufacturers only give the PIR. It's not consumer friendly.
Put the water from the 2 gallon jug into the 3 gallon jug oh wait to get exactly 4 gal oh wait... wrong movie
Think that may have been lost on alot of people 😀
Yeah but how many were going to St Ives? 😂
Very helpful video. Think I’ve been doing it wrong up to now i.e using far too weak a solution.
Maths totally lost me so I'll just copy your measurements instead 😂
Good honest video john.totaly agree I use many of the range you spoke about and judge others ajainst b h , you will not be disappointed with any of there products.they form the backbone of my detailing arsenal.thanks john
I have a Stihl lance which I calibrated requires 800ml product in a 1litre snow foam lance bottle for 4%, 400ml for 2% and 200ml at 1%. I tend to use it at 4% as the truck only gets washed every 2-3 weeks and I live in the sticks. If I washed it weekly and lived in town, I’d use it at 1%. Try different concentrations to see what works for you.
I use a pump foam sprayer and a lamce foaming gun and in the pump gun i use 75ml-1500 water goving approx 5% concentrate and in my lance i use 350ml and 650 water and i get great results. Car is coated with tac moonlight and that really helps reduce dirt clinging to the surface
I have no idea what I'm doing wrong, but I go through the snow foam far too quickly! 😂
I'm using about 90ml of product in my 600ml container (2% pir) which according to Bilt Hamber's website is the ratio for really dirty cars.
They also say this should last 4-5 washes!!
I barely get round my car before it runs out 😄
Once you worked out the 4%, just divide it by 4 to get the 1% for the 125ml (I think you worked with 500ml at 4%). But when I've tested on my K2 and K7 I found it's nearly always just under 50-50 in the bottle for around 4%. The thing i've found more important is the flow (especially on the K7 as the pressures generated can be so high) and the adjustment on the lance to change the flow. (Which I think is what you've said in the video anyway!). I normally keep the the setting around 1 for foaming.
So 50-50 in the bottle is ok?
Lost me pretty early on this one John, do a video riding the pogo stick on top of the cupboard tho
Thanks John, just got touch-less foam this will be good enough for me, I also have 1lt foam bottle
Am I glad to see this video! I’ve just been guessing so far with auto foam
Guys the easiest math for this is simple: In the example he used he produced 12Liters or 12000mL. So just take off 2 zeros (dividing by 100 for 1%) and you get 120mL of soap to add to get 1% PIR. And if you want 2% its 240mL and so on dead simple.
Helpful video just bought some so I can get started cheers.
I’ll need to watch this again... kind of lost me in the last couple of minutes :( However great tip on marking the setting on the Lance :)
John, I was literally about to google this as I'm having less than impressive results with the product using at 5:1, but I've seen such good results from your recommendations. This may have answered why!
should be good at 5:1 reember though jack its not going to strip all the strip off. nothing can.. but its as powerfull a road film remover as I have ever seen.
thanks for the video. 50/50, 40/60, 45/55 all seem to be the range for most users. I might just cheat off your homework John, lol. Cheers !
If you prefer to premix a ratio of solution into something like a capro dilute bottle i found it easier to do
for my lance:
1L / 13L = 0.77 = 7.7%
target PIR = 2% = 0.02
0.02 / 0.77 = 0.259 = ~25% = 1:3 in my carpro dilute bottle.
Love your passion to get the answers
Amazing snow foam, bought on your recommendation using it with the mjjc (again on your recommendation) such a wicked combo mate
I do 200mls BH and 800 mls water and it’s fine but but I always citrus wash first too
Big thumbs up for this I've been struggling to work out the mix ratio on this bilt hamber snow foam
All this time I been using it wrong , I use 100ml to 900ml water , I still need to see how much ml my pressure washer makes to know for sure , thanks for the heads up
I was doing exactly same thing 100ml to 900ml, simplified I fill the bottle between 1/3 and half solution and fill rest with water
I've been watching all your vids on this soap. It looks awesome and very reasonably priced at $20.00 dollars US a 5L which is on par with discount brand stuff here. Shipping it to the US is killer though at 41.00 US dollars. Uugh.
Perfect! I get it now what snow foam lance and bottle are you using? been looking for a better one that the plastic one I have, waiting for my new karcher to turn up 🤣 Love the videos keep them coming I do really enjoy watching them
Brilliant description dude 👍
I enjoyed that one. Good work John.
I did this for my Kranzle 1152TST a month or so ago. It was 15 litres meaning 4% it's 600ml. When you sometimes wash 4 plus cars a day thats a lot. I reckon I'm going to go about 300ml, which is roughly twice what I'd been doing until I did the test.
Watching this today (18 Feb 2022) and Storm Eunice approaches as presenter from a video a year ago says, "storm is coming" at 2:40!!! Spooky man.
Presenter = John. 😊
What I don't get is why BH seem to recommend 4% PIR but on the front of the bottle is says use at 1:100 (1%PIR)
I'm a huge BH fan and won't be using any other snow foam but IMHO it's not cheap. I need 450ml in my lance to get a 4% PIR, this means I get 11 uses from a 5 litre bottle which in reality with shipping costs about £22.90 at the cheapest, making each wash £2.08! I'm happy to pay for a superior product but cheap it ain't!
I plan to try a lower concentration as Jon has advised. Maybe 2% PIR. May try the 1:100 though I struggle to get my head around that working as well.
I'm guessing that someone may have already said this but if you don't have a bucket with a measure scale on it you can always just weigh the bucket of water on a set of bathroom scales. 1 litre of H2O = 1 kg. Don't forget to deduct the weight of the bucket if you want to be really accurate!
Man, i did not think that way. i got mindblowed haha
2 inches in the bottle for me, cleans perfectly, doesn't hurt wax job done
Jon, my understanding is that 1:12 is correctly stated in that the number on the left refers to the product parts and the number on the right refers to the TOTAL parts as opposed to the WATER parts. For example, a ratio of 1:12 wouldn't mean 1 part product added to 12 parts of water (13 parts), it would mean 1 part product in 12 parts total. Therefore a 1:12 ratio would be 1 part product and 11 parts water giving you a total of 12 parts.
No you have it wrong. At least I think you have it wrong. my understanding is 1 part product to 12 parts water. so 13 parts in total.
For example I have 6 sweets you have 3. Our ratio is 6:3 and theres 9 sweets in our little world.
Say you make a glass of orange. you put 1 part orange in and 4 parts water in. your ratio is 1:4 (5 parts total)
I used to understand it the way you did as well but someone corrected me years ago. who knows maybe Im wrong though. but actually I cants be wrong. here is how to prove it. 1:1 part product to 1 part water. thats a 50%/50% ratio. but there are 2 parts to the system so total parts equals left +right side.
@@forensicunplugged4295 There's no disputing the last part. Cheers for the explanation, Jon 👍🏻
I am going to buy this bilt hamber auto foam but I see people saying it doesn't foam well
Is it possible to mix it with another type of snow foam which gives a thicker foam ?
my question too! I was thinkin to buy BH and try adding some avalance in it.
Just as a note, the size of the snow foam bottle is irrelevant as long as you mark a ‘full’ line on it. The ratio is worked out from the total volume in the large bucket to the amount of concentrate needed in the snow foam bottle for the pir you require. Your maths is good. (Have a look at your 1% pir example and you’ll see what I mean)
true dat yer in fact you would save some water wouldnt you if you did say 250ml drain calculation.
@@forensicunplugged4295 The reason I figured this out in the first place is I used to have a nilfisk cheapo snow foam bottle that was well under 1 litre, so I couldn't copy the guide on the Bilt Hamber website. I marked the bottle near the top and filled with water to the line and dispensed it into a large bucket, then multiplied the amount of water collected by 0.04 to find out how much Auto Foam I needed and then marked that line on the bottle. These days I just use SurfexHD at the same dilution, and have some in a 5 litre pump sprayer at 1:9 for wheels/tyres/arches. Use it all round the house too, I've learnt a lot from your channel, saved me some money and cost me some too! All good fun.
At last someone who knows the maths! I've seen numpties on DW quoting it has to be 1 litre... well said @squadmeta
Thanks Jon 👍🏻
I tried this method with PA foam lance 1L bottle and Karcher K2 silent.
But I found difference of the lance's mixture rate between pure water and shampoo water.(Both mixture knob is MAX "-" rate.)
When pure water, I need 8L for getting empty bottle, and shampoo water only need 3～5L.
I think this difference by viscosity of bottle contents.(May be)
So I fill bottle with 100ml auto-foam and 900ml water.
Great video thanks
Do you ever use hot water in either your contact washes, or with your pre wash bilt hamber auto foam?
my pressure washer only gets cold water, but when i mix in foam bottle and mix in the contact wash bucket i always use hot water because hot water have much more cleaning power than cold water :)
Great video 😀👍
I tried 200ml in a litre and it was completely ineffective. I’ll try 500ml instead. That’s a lot of product for it to be effective though. Suddenly polar blast doesn’t seem that bad.
You will only end up using 200ml of the dilution on 1 car depending on size of the car. I can wash my 2 cars twice over with a mix of 500ml of product to 500ml of water. This stuff is dynamite.
You could always weigh the water for an accurate measure 👍
Correct me if I’m wrong but I would have just multipled the quantity of combined liquid hitting the panel by 4% ie 12000 x 0.04 = 480ml of product to 1Lt of water
hey Jon great entertainment as always,
this is great for those that use metric.... in the USA we do not use metric... clear as mud.... arghhhhhhhhh... It blew me away how much the water grows coming out of the cannon...
I have a basic Karcher snow lance and my after emptying the lance i had collected 18 ltr and my calculation seemed to suggest that even with 100% autofoam i would still only get 3% PIR
I have a cheap pressure washer so to get good results I had to use no water in the foam cannon,only product,is this correct?
Hey there, i just blast a load in and hope for the best its cheap enough. Whats happening with your springs and ECP ?
Yes John!
BH Autofoam is one of the best on the market, but I’ve always found you need a lot of product through a foam lance to achieve the 4% PIR. Imo, anything more than 100ml of product to make 1L of snow foam is a bit too much. I think Autofoam is best used through a pump sprayed or foam sprayer as a prewash instead of a snow foam. It’s not the best product through a lance as it’s quite runny, making it hard to use in the summer and tricky in general as it doesn’t dwell long. I prefer to apply it to where the dirtiest areas are through a pump sprayer, let it dwell, then blanket it with an economical snow foam on top. Always works for me. You can achieve a 4% PIR easily this way as you’ll only need 40ml to 1000ml (1L) or 80ml to 2000ml (2L) depending on the size of the sprayer.
some guys want like a thicker foamy product that clings more and they can work with a brush. I tend to use it through the lance but I run about 1:5. I find it doesnt really need to dwell like other products. the thing is, even if the suds roll off more the surface is still wet and the dirt is soaked with the product. But this product does not really need to dwell like other foams.. or let me say its faster acting.. but ive talked so much about autofoam over the past few years Im really looking forward to exploring some different products in the next shootout.
I'm still using a Karcher 6.80 - years and years old. 16L to empty a 1L PA Snowfoam lance bottle. Calc for 4% PIR is still 600ml in the bottle. Think I'll dial it down to 2% and double the usage.
Megs Autofoam last ages and ages - years infact - for £30. Am I getting the same money's worth from BH AF at £17 per 5L? I may well do now at 2% PIR instead of 4%. That would be too costly tbh.
I find works better with filtered water,curse our hard water Jon. Clean bins by the way.
I normally use autoglym pb..I just got some bilt hamber snow foam just to give it a try earlier this month which i not had chance to try.. Since i got it we had heavy rain 2 bad storms
I just wondering what you guys think of it?
And John would it be possible to do a review on the new autoglym UHD ceramic coating but it your call 😁😊
if I want to use only surfex hd in a 1 litre snow Canon how many ml of surfex should I mix up to water to be the most powerful but without damaging the cars paint?
(I tested my 1 litre Canon with my pressure washer to check the PIR and it emptied all the liquid inside the Canon into a bucket and it gave me about 14 litres)
Anyhoo, its the reason I don't use AF through a snowfoam lance. I use it through a Garden sprayer instead. 200ml in a 5lt pump sprayer and that gives 4% PIR and enough made up product for 5 cars, against 500ml, in a SF lance, which could do you 2 smallish cars.
yeah it seems this stuff wont last using through a foam cannon seeing how much the pressure washer dilutes it.
My BH Auto Foam is now reserved for when I want my wax removing from the car. Gave mine a coat of Meguiar’s Ultimate Paste Wax 3 weeks ago. Used 150ml BH Auto Foam + 850ml water in my Foam Lance. Left it to dwell for 5 minutes and stripped the wax completely off the roof and bonnet, and practically stripped it off the vertical panels. Thought it was supposed to be wax safe?
short answer is, it is wax safe. That paste wax you are using does have poor chem resistence though generally see my halfords paste wax comparison video. But there is a flaw with your logic and how you view this product. a paste wax will get buried by dirty and a pre wash wont be able to remove all that dirt. so you may well see little or no hydrophobic properties after rinsing with autofoam. but you need the contact to break the dirt away more. Problem contact cleaners is they tend to be cationic and they mask more. so theres lots of flaws... but I could put ultimate paste wax on a panel and do about 15 applications and dwells to a test panel and the wax wont be gone. It does not strip. there are other factors at play here.
Forensic Detailing Channel Thanks for your reply Jon, something I’ll bear in mind. Not an expert at detailing by any means and always looking to expand my knowledge. Hope you got sorted with Euro Car Parts.
Is there something wrong with my set up?? Kranzle 1050p PW and AD snow foam lance.
I've just emptied 44 litres into a container and my foam bottle still had a bit in the bottom??
Works ok generally so no idea :/
Does anyone use a Bosch easy aquatak 120? If so have you worked out how much product is needed in the reservoir bottle to deliver 4% PIR? You'll save me the hassle of doing it myself. When I get round to it I' ll post the result!
Great video as always. 👍
Update. I used 480 to 500ml of Autofoam. It seemed fine
I tend to find 1 litre of snow foam is too much to do the average family size car, as i always have loads left over after foaming the car.i think about 600 to 650 of mixed solution is more then enough ?
I have to use a pump sprayer, any idea how to work out the amount of product to use in that or does it only matter with a pressure washer/snow foam lance?
After a bit advice with auto foam I am getting 16 litres out my 1 litre snow foam Lance how much product tk water do I need
Great calculation :) But what if I am using foaming pump sprayer? Which dilution ratio will be to get the best result with BM auto foam?
4% max PIR so thats 1:25 in the pump foamer mate.
Isn't it 1:24 in the sprayer?
In 100ml:-
1 part (4%) is....
1ml * 4 = 4ml product
That leaves 96ml of water
96ml / 4ml (which we know is is one part) = 24
So the dilution is 1 part product to 24 parts water (4 + 96 = 100 in our example).
Happy to be told I'm wrong.
I love Bilt Hamber products. I have to say though, I just fill my lance with neat solution and it works very well. Whenever I’ve diluted it down, not so good.
watch out for soap stains in the summer.. I wouldnt use it neat but hey if its working.
Forensic Unplugged I just found that when diluting it down it wasn’t very effective in my lance?
On a Karcher K2 with In2Detailing foam lance I need neat autofoam in the bottle to get 4% PIR
Matt I use a K2 too with neat solution.
@@Matt-bt7ej I use autobrite foam Lance, karcher K2. I find this bilt hamber snow foam crap. I'll try the 50 /50 mix next wash, if I'm not satisfied that's it.
I got 16.5L of water in the bucket from a 1L snow foam Lance with my karcher k5? And based off the calculations I got 660ml at 4% pir surely that’s not correct?
Do you use the same numbers for a hand pump sprayer? Cheers.
no mate a hand pump sprayer has no water feed.. so whater % you use in the pump sprayer is the PIR. EG 40ml autoform to 1000ml is roughly 4%
@@ForensicDetailing cheers bud
John,
How does Autosmart snow foam pro compare to your other snow foam products. Have you tested it yet or do you plan to. Regards Chris
got a cool snow foam video comparison coming soon. Autosmart stuff is fine if your in the trade and you can get it from a proper supplier. However its high in NAOH... I dont tend to recomend it for guys at home using week in week out. A hell of a lot of guys buy it and punt it as a sideline on ebay. Theres also been issues with AS products being sold watered down on ebay etc... you have to be carefull with what people tell you.. over the last few years Ive had a lot of guys bombing the comments of my videos plugging Autosmart, stuff like "korosol is weak I got much better results with AS red7" this sort of bollaxs... etc.. with autosmart ultramousse your gonna be forking out 38 quid on ebay for 5 litres.. thats damn expensive for a caustic trade product, when you can get autofoam for 17 quid.
Thanks mate. I was a valeter 20 years ago so my car does get quiet well looked after. I get my products directly from an Autosmart guy at his lock up so is all genuine stuff and although it seems to work well, this is the first time I’ve used it. I used it at dilution of 50ml product to 950ml water, wondered if you had compared it to Bilt Hamber as I may try BH next.
Didn't see you as a Sun reader Jon
Please give me a simple answer...I want to use bilt hamber auto wash in my 1l lance and I do not want to touch the paint after foaming, woud I be correct in saying that I need 4% PIR for this to be possible or do you recommend that I do hand wash after foaming? So, to get 4% PIR how much ml of product must I use in my 1l lance? thanks
Ok Autowash is not designed for foam cannon application. but its intended PIR usage ratio in a bucket is 1:1000 to 1:2000. 4% PIR is closer to 1:25. So your using way way too much product there. The whole snow foam lance thing and foaming a car.. A bit part of this is just because people love foaming a car. but covering the car in foam does not really do much, covering it an an effective cleaning solution does, and that cleaning solution does not really need to foam. You need the contact wash shampoo to do some simple things, provide a bit of lubrication, degrease and saponify oils etc, soften the water, inhibit corrosion. And thats it. so put the autowash solution in your bucket.. You HAVE to touch the paint after "foaming" You cannot do a contactless clean of the car, contact breaks off dirt that detergents cannot do, contact has to be made.. The fact you call it foaming suggests to me your american. Foam does nothing. You have to buy into this system. use the BH touch-less product to ensure the car feels clean before the contact phase. do the contact phase. rinse, dry done. AW will not be foamy or sudsey. If you want that just buy chemical guys stuff.
Easier way to do this with your example of 12000ml in the video. If you want a PIR of 4% that is equal to 4% of 12000. And that is 480 ml. That is how much cleaner you add to that 1 L cannon.
Hi ... I wanted to ask ... is it safe on coatings ?and if yes in with dilution ratio?...thank you very much for your time :)
yes mate use 1-2% pir for normal soiling 4% for heavy heavy extreme soiling.
@@forensicunplugged4295 thank you very much :)
Built Hamber recommendation is a PIR of 4%. So I have a Karcher K7 quick release same set up as John. Fill your foam lance bottle with exactly 1lit water, turn mixer knob to -position fully closed . Now spray water into empty bucket until the foam lance bottle is empty. The amount of water in the bucket in liters x by the 0.04% BH ratio the pir(Panel impact ratio) this will give you the amount of product to put into bottle.
+ Right more water less foam, - Left more foam less water.
Mine is Karcher k7 quick release set at 2.5 at gun. 12.7 liters x 0.04 = 508 ml snow foam 492 water.
At 3% pip 12.7 x 0.03% pip = 381 mil product
At 2% pip 12.7 x 0.02% pip = 254 mil product
Happy snow foaming.
i'm struggling like mad with the maths just tried to work out mine and completly confused lol.
my results worked out to be 1/24 (in litres), when i wash my car i only normally use 100:500 p/w, but it's not doing the best of jobs.
don't wan't to use a full 1l bottle as for shampoo i use the autoglym polar wash, and only have the one bottle.
could anyone please shed some light on what my 4% would be based on a 600ml mixed.
I run BH SF 100ml per litre lance. I use a k2 BTW. heavy soil I run 250ml per litre lance
John, do I need to fully open the Foamcannon when i'm spraying it on the car too? Then its not very cost effective..
just adjust the mixer nozzle until you get the thickness you want. but you will alter the PIR but no big deal. its just to get a roughly correct PIR
This will be expensive for me. My canister is 1000ml. My pressure washer is gasoline.
3000psi 2.8gpm. Soap on full and nozzle on sprayer selection for regular washes.
I got 24l of water sprayed off one canister. So that's 24 x 0.04= 960ml of product.
I might as well just fill the canister itself with product for 4%. WOW!
john what would you recommend for a standard foam wash of auto foam
I regularly buy this product as its brilliant but I am now going to get my car coated with a ceramic coating which has a PH tollerance between 2 and 11.
However I am now concerned about using Auto Foam as my pre wash snow foam as it is PH13 and it will have a negative affect on the durability of the coating.
I look forward to your thoughts on this John :)
I was wondering. Does the the volume of water that the pressure washer is pumping out affect how the dilution is right? On my system i got like 18 liters of water out of one liter bottle. So at 4 % i have to mix it like 700 ml product and 300 ml water to Get the 4 % out of the lance. If i buy i pressure washer with a higher flow rate will i Get less or more total amount of water if i do the test again?
you need to redo the test with different pressure washer mate.
@@forensicunplugged4295 my poor english. Sorry. Offcourse i know that i have to do it all again☺️ i was just wondering if i bought a new system with a much higher flowrate of water that the 18 liters of water goes down under 10 liters total amount☺️
I slightly understand the video. But with 12,000 x 0.04 to work out the amount of auto foam. Seems a lot. Do you empty the whole 1ltr bottle or store it?
Instructions say you can store it
What about putting the product raw into the bottle and let the lance’s swivel wheel adjust the dilution? Does this pre-dilution method require the lance to be at its ”most effective” setting having the adjustment knob turned all the way to maximum? In Finland, where I live, winters are extremely salty and grimy (much grimier than yours, trust me) and a 4% ratio wouldn’t do that much here... People tend to even use 10-20% Surfex HD (or equivalent) before BHAF only to get rid of the salt in pre-wash stage.
And yes, 10-20% might easily strip off any protection, but that’s simply how it is. You can’t expect wax to last in the winter here and the only methods would be a very strong and high quality ceramic coating or a wetcoat/bathe+ after every maintenance wash. If you don’t use strong pre-wash products you’ll just end up scratching your car’s paintwork with excessive amount of stuck dirt in contact wash stage.
@@sivuluisu5801 I don t do that, its just too over concentrated for me.
@@forensicunplugged4295 Totally understandable. Here the road agency likes to use (A LOT) salt (sodium/calsium chloride) that is known for bonding extremely tightly with cars' paintworks and doesn't come off easily, especially if the car is kept indoors when parked. Therefore a strong APC or solvent-based degreasers are required for pre-wash and we can tell the salt isn't off the car (surface roughness etc) if we use mild "summer" products/dilutions. For instance, in winter time I like to spray 10% Surfex on door panels and boot, then spread raw BHAF on top of it from foam lance, making it around 8% dilution. This gets majority of road salt off, although not all of it. Sometimes even a tar remover is required. Only after this the paintwork looks clean enough for contact stage.
John what the recommended pir of autofoam ?
I think BH say 4% now even though the bottles says 1%
Is 150ml in the lance rest water 1ltr lance still affective
Hahahaha still confused 😂😂 but I've never been the brightest 😂 150ml auto foam to 850ml works bang on for me using a k2 karcher.
Dave Graham I’m glad I found your comment. I too have a K2. How do you find the foam thickness? I’ve been using 1:9 in a 1L bottle. I find that’s too thin. Go for upping the quantity?
@@adamh9126 bilt hamber auto foam isn't a foamy product, I love the power of it and all bilt hamber products.
@@adamh9126 you could definitely up the product ratio but I just think you're wasting good product.
Im a bit lost please help : if i put 50/50 in my lance thats 1 to 1, i get that ... But isnt the 50/50 in the lance then diluted again as it goes through the gun ?
yes. thats why you need to calculate PIR with pressure washer snow foam lances. See sticky comment or description for easiest break down 50/50 is close to 4% PIR. 25/75% is close to 2% 12.5%/87.5=1% pir etc.. once you remember 50/50 =4% you can work out the next steps
