A little tip for you Dan. When pouring from a 5 litre container like the Kilrock PRO you used, turn the container so the outlet is at the top. You then don’t get that glug,glug splash problem and have perfect control of the liquid with a smooth pour.
I guess that you have not read the safety data sheet on this product. It’s highly corrosive and should be applied using full personal protection. It is also hazardous to marine life
Especially good advice when it’s a 20litre container. Doesn’t have to be fully upside down. Hold it so the opening is at the side. You’ll find the sweet spot and it pours smoothly.
I use Wet and Forget for cleaning block paving, fencing and brickwork. Never had a problem and ive not used a pressure washer on the paving in 10 years
Great video for an age old problem. I get loads here. I will be trying the Kilrock after this but have also had success, on concrete, with Jeyes Fluid used with hardly any dilution. Thanks again for the video.
I use Q CLEAR from TM Chemicals, brilliant stuff but expensive @ £39 per five litres but is highly concentrated so goes a long way and most importantly it works with no scrubbing. Great video.
Nice video , Ive been using a glug of bleach in a bucket of water , I pre wet the wood first before brushing it on . Not the most environmental solution ( and the opposite of your vinegar ) and the place smells like my old school hall afterwards but it works
Thank you. I use sodium hypochlorite on the patio which is just strong household bleach, it works wonders on that, comes up like new! That video is out on Sunday and a pretty satisfying transformation!
@@Renovation-Dan I’m fairly certain I’m not the only person who reads comments on videos like this, I might save someone some cash if they decide to go down the vinegar route. There’s plenty of other uses for it aswell…
Not sure why you did not mention the vinegar strength, but it's usually 5%. You can buy vinegar for much cheaper, just look further down, you can get like 20l for near same price. Vinegar can be used to clean pretty much anything so don't buy expensive. A few more washes and it can do the same, I reckon.
You could add a bit of salt to the white vinegar solution to. I've just sprayed the shed and it's killed the algae in a few days. BTW white vinegar is acetic acid and some commercial eco 'remover' products will have this in their ingredients. It's used because it's biodegradable.
This particular wood is a nightmare to clean with a pressure washer, it either streaks or at higher pressure starts to damage the wood fibres. The bricks and pointing are 130 years old, so I won’t use a pressure washer on them as it damages them and pulls the lime mortar out.
Thank you. I’ve had it a few years, I got it from toolstation I think. I know you can get a ronseal version which is for spraying fences but I’m not sure I would use something like this for fences. You’d have to thin the paint loads to spray it well. For fences I use a Wagner sprayer, you can get cheaper versions now for around £20 which would be a better bet for spraying fences.
That’s not one I’ve heard before, I’ve heard of people using fabric softener for cleaning artificial grass and removing smells, but not washing powder for getting rid of green algae
I didn’t realise it was only wickes that supplies it. I’ve had a quick google and can’t see anywhere else. I’ve had a few people recommending “wet and forget” as a similar product with good results
You could just fill your sprayer with water and add a couple of cups of thick bleach to it. Cost about 25p per sprayer container full. btw bleach does not harm bricks or mortar.
I’ve heard a lot of people (including lime suppliers) say that the sodium in bleach reacts with the lime in lime mortar causing damage. Cement mortar would be fine though.
@@Renovation-Dan I've heard that you can get salting when used on lime mortar, I think this is more cosmetic than affecting anything structural. But most mortar nowadays is just made with sand and cement and doesn't contain lime.
@@caparn100 a lot of the stuff I’ve seen doesn’t really specify the damage, so it may just be cosmetic. The mortar on our house is mostly original lime mortar, other than the various patches that have been repointed over the years with sand and cement. The patio always gets cleaned with sodium hypo bleach and it works a treat!
@@Renovation-Dan For my patio, a couple of times a year I use a bucket of water with about 1/4 of a bottle of bleach and just brush it over and leave it to dry. It does a good job , and every couple of years I jet wash it. It's quite dilute so doubt you will get much salting, you could try it on an inconspicuous part of your house and see how it goes, maybe make a video of it. I found that jet washing does the most damage particularly if you have the pavers that are concrete with a coating to make the look like sandstone. The jet wash wears away the surface and exposes the concrete paver if used too much.
@@caparn100 there’s a video on the channel cleaning our patio, it’s sandstone so pretty tough but I know a lot of people make a right mess trying to jet wash stuff. I’ve seen a few decks people have tried to jet wash and made them look 10 times worse!
All overkill, just use a 50/50 water bleach dilute in garden sprayer, soak all the green stuff then hose away a day later - just be careful with the run off around plants.
That’s more effort than the killrock, which you just dilute, spray on and leave. I wouldn’t want to leave bleach on the surfaces in the garden having a dog either.
Vinegar is highly, highly overrated as a home cleaning remedy. First off, it's an acid and should not be applied to a myriad of materials that it will damage. Those galvanized hinges on your bins will suffer from being exposed to vinegar. Unfinished wood will not fair well in the long term after vinegar exposure. Additionally acids are not completely removed by water rinsing unless you apply huge amounts of water for a very long time. Neutralizing the acid with a sodium bicarbonate solution would be a good idea, but even that might not get into all cracks and crevices. Side note - don't put vinegar in your clothes washer or dishwasher as it can damage rubber and plastic parts. The only thing I use vinegar for generally is killing weeds - it's pretty good at that.
I’ve used it on moss before and it does work but it takes a while. In the next video I clean the patios and use sodium hypochlorite to remove stains etc. Theres some moss on the edge of the patio where there is a sleeper and brick border and the sodium hypo kills it pretty much instantly. If you haven’t used it before, it’s pretty strong stuff but it will get rid of moss at a fairly diluted solution.
Some algae can be harmful but to be honest I have no idea about the different types. I doubt these ones are harmful to humans or pets (other than being slippery) I do it for the looks and to prevent the wood potentially rotting sooner
I P1SS myself laughing every year at the Woman / Family next door, she'll jet wash her driveway about 72 times from Now till Oct - maybe even a few in November. I do mine ONCE, and with No Jet wash. Vinegar Concentrate, 1 cup of salt & about 20 mil of washing up liquid, I mix up one of those big ''Water at Work bottles'' then add to an old watering Can that holds 5L, Usually the Big ''Water at Work bottle'' is enough for the full driveway, I done it about May last year and even now it still looks fine, zero weeds, zero moss, but I will still do it again in a few weeks just to keep next door guessing lol 😉 Vinegar Concentrate - 30% is plenty strong. cup of salt 20 ml of washing up liquid Shake well and apply, large spray bottle or watering Can BOSH! Ya welcome.
Brinton's is your Boy for this it works wonders and you can even spray it on your annoying neighbour's cat that visits your property to leave you special presents 😶

Bleach, caustic soda, biological washing powder! ☹️All these are bad for the environment and aren’t recommended for first choice as cleaners because of residual damage to good organisms. Dan is right. The Killrock is safe and works well when diluted as instructed with no environmental damage.
The next video is cleaning the patios and path, I’ve used sodium hypo on that which works well. I got the slabs second hand and they were pretty much black with lichen and the hypo had them looking like brand new again.
@@Renovation-Dan little tub 1 litre goes a long way not cheap but used it on my outside walls that were north facing and greener than the lawn…came back a few days later and the walls were whiter than a vergins
@@1664smudge I looked at it a while ago and I think the prices must have been up, because when looking this time round it seems to have dropped a lot from what I remember. I think I’ll get some to spray our roof, I had someone else saying it worked really well for roof cleaning
The best way is just to leave it alone and accept that's the way it's supposed to be in Winter. Splashing chemicals around is a complete waste of time and money and bad for the environment. The green will go soon on it's own and return next Winter. You're effectively chasing your own tail and filming it which is akin to admitting you have the intelligence of an animal.
Well here we are at the beginning of May and my composite decking shows no sign of 'improving'. Granted it doesn't get as bad as wood, but with the foreseeable weather forcast not amounting to many sunny days I cant see the algae disappearing anytime soon. So I will be jetwashing in order to have a pleasant area to sit in. I only need to use a small amount of washing up liquid to help the job along, but I do not blame people for wanting a clean and pleasant area to relax in😊
What a load of rubbish - just buy some spray bleach / £1.99 from Tesco - for bigger jobs including large patios / wet the patio and squeeze the domestos out all over it and brush it in - results a near new patio outcome / these people online our online wouid would have you buying a jcb to dig a hole to plant a flower / 😂
That works out more expensive than the killrock pro. Even if you buy Lidl bleach that costs 60p per litre, it adds up to £30 to make 50 litres worth, more than twice the cost of the killrock pro. For cleaning the patio I use sodium hypochlorite but using bleach isn’t as pet or kid safe and you obviously need to be very careful around plants.

The Greening of Garden Timber and Concrete products seems to be more Intense last couple of Years 🤔 or is it me? ☺️

I use Wet and Forget for cleaning block paving, fencing and brickwork. Never had a problem and ive not used a pressure washer on the paving in 10 years
I’ve heard lots of good things about wet and forget, will definitely have to try that out in future.
I’ve been using caustic soda. Instant results and turns even old decking into a lovely honey colour. That said I applaud you for trying.
Caustic soda will degrade the surface of the wood & shorten its life.
What ratio do you use???
How much do you put in water?
@@Tonisuperfly half a mug to builders bucket of hot water. This is 100% product not available in shops. Less would probably do but that’s my ratio.

It also works as a weak weed killer, although it only really damages the leaves, it doesn't reach the roots.
