This video is about how and why to passivate your stainless steel fermenters and all of your stainless steel brewing equipment easy at home. In this video, I use citric acid to passivate a shiny new stainless steel fermenter, brew kettle, and other brewing equipment. I also explain how to use Star San to do the job. Hope you like the video.

Never heard about doing this before, may have to give it a go on my boilet. Cheers
Try it!
After doing this and allowing some time to air dry do you just rinse with water before your next brew or must you wash with alkaline cleaner?
great vid carbination in that glass looks perfect
Thanks Bruce!
A great video! I am moving onto as much stainless as possible & this is the first time I've come across passivate. So this was all new to me & I found the video very interesting. It left me wanting to know more of the why to passivate & the importance of passivating your stainless equipment. Which I felt didn't come across in the vid, so I will need to research this further. Thank You so much for teaching me something new, which I didn't know about before. 👍👍👍🍻🍻🍻 All the best and Mash On!
Thanks, you passivate it to remove free ions and form a protective surface of chromium oxide. It prevents it from rust. Also leads to better beers as non passivated stainless steel can transfer metallic flavors into the beer. It was all mentioned in the video. If you treet your stainless steel right they can serve you a lifetime. It may even help with boiling more efficiently and make cleaning easier. Not mentioned as I really haven't done enough research on that.Cheers!
Thanks for your reply, Yes your right what you've mentioned above was said in your video. Removing free irons (did you mean - ions) may go over some peoples head, as I don't fully understand it. I get the protective layer👍 (the why), but stainless doesn't rust without any treatment anyway (thats what I understand). The importance bit I would say is the transferance of metallic flavors into the wort/beer (I am trying to boil down the information). The information I remember about why you should put oil in your car is, oil reduces friction, heat and lubricates (why). The importance is:- By not putting oil in your car, your car engine will seize and result in unrepairable damage (cost effective) leading to a replacement engine. So here; by passivating your equipment you provide a protective layer (why), no metallic flavours imparted into wort/beer (importance). Is that it or is there more? Is where I was left after watching the video. As I say this concept and method is new to me and is the 1st time I've come across passivate, so I really appricate 👍👍 the information. The introduction to passivate from your video is great, I was just left thinking would I benefit from doing this on my equipment, do I really need to passivate. In the same way as putting oil in my car engine, that part didn't come across in the video as effective as it could have been. I was sold on the concept. Cheers 🍻🍻 Thank You and Mash On! Keep Em Coming!
@@Zandebrew Yes free ions not irons, sorry. Stainless steel definitely can get stained. The bottom of my sparge water heater for example was heavy stained around where the element is. Probably caused also by the high iron content of my water. The passivating took that away and it's nice and shiny again. How long it will stay that way I don't know. My kitchen knife had a few stains also. Now it don't. This was the first time I did this. I wanted to start "right" with that new fermenter. But as it wasn't hard to do this and I can do all of my equipment in an afternoon I will definitely do this again. How often I can't answer right now. The future will tell. Cheers!
I first wash everything with PBW after each brew day and circulate starsan thru everything before each brew day. Works for me. Cheers
Cheers buddy, thanks for watching and commenting.!
Is Fivestar chemicals StarSan available in Norway. In the Netherlands almost everything is out of stock due to EU new chemical regulations or somekind of bullshit.
sodium hydroxide naoh is my second option to clean ss 304,316. 4 Euro per kilo. citric acid cost 25 euro per 5 Kilo.
@OldNorsebrewery do I NEED to use citric acid to passivate my new stainless steel kettles or can I just use Star San (like the instructions say)?
I’ve never thought of running citric acid through my coffee machine until today, Thank you! I will be doing that soon. Also, great video on the Passivation process!
Thanks! I thought everyone used citric acid to descale their coffee machines. Do it! Merry Christmas 🎅
At what water temperature I should do this?
Hi and thank you for this video
If I use Star san (at 4 times the concentration as you said) , when all the equipment is dry, should I rinse it or isn't necessary?
Thanks, I would just rinse it the next time I where to use it.
Cool video as always. Just curious what’s the maximum grain bill your brewing system can handle?
Thanks. Ive gone just over 7 kilos some times.
Can you pasivate with starsan? Do you pasivate your kegs?I have so much stainless touching my beer should I pasivate everything? I have bright tank, pipes , till beer taps
Great video as per usual doc! Any issues using hard water as the base for the citric acid solution?
There's a lot of conflicting info online and I've seen some people say to use RO or distilled water.
My new local water is quite hard and high in PH. Thinking I would just use a higher concentration and for my tap water.
What you think?
I think as you do. It's a PH thing. So any water would do. But of course as is a PH thing different water will give you a slight different PH. Doing RO or distilling water for this sounds like a waist of time to me. Then I wild just add more acid as you say.
Most beer and wine making gurus say that it's not good to use stainless steel containers for fermenting because the stainless steel contains nickel, some of which will leach into the finished product. Most of the guru's websites recommend using food grade plastic buckets as the primary fermenter.
That's another interesting topic!
Doubtful
Once it's pasivated you shouldn't have that problem anymore. That's the reason for doing this, use a cloth for cleaning so it doesn't remove the pasivation. Using a scrubber and making shiny again will remove it.
Hi thanks for the video! Is it no rinse necessary after the passivation with citric acid? I have read many articles which suggest the opposite (immediate rinse after the treatment). Thanks
I'm not an export, to my understanding this method is fine but...you do need a good rinse before using it.
Do you use caustic soda to clean your equipment?
Btw .. citric acid is also very nice for cleaning your equipment .. if it is not plastic stuff .. it is my usual method to clean my fermenters which are made of glass ... Found out that it removes all this nasty fernentation dirt .. also after cooking water to make it less hard it is a good way to clean the pots of course
Yes it is. Like I mentioned I after I was ready passivating.I boiled the liquid up in 10l batches and pour it down my drain. I get a limestone build up which can get my plumbing to clog up. Ive could have saved for cleaning as you say. Another good cleaner is vinegar and baking powder mixed. Cheers!
@@DrHansBrewery I just prefer natural not poisonous stuff for cleaning my equipment. Citric acid is also smelling good and has a nice taste if there are some leftovers in the equipment ;)
Meget bra video som vanlig
Tack, kul att du gillade den!
I got a small rust stain in my Grainfather. I don't know how I got that, but would be good to treat this with citric acid or Starsan to get this removed and passivate the inner surface?
It worked out great for me.
I miss your grain to glass videos!
I will make one soon I promise!
Vilken temp har varmvattnet du använder?
Can I use any old citric acid? My local supermarket sells Ball Citric Acid and I’m wondering if that’s good?
Any acid would do the trick
Can you tell my friend the nitric acid method ? I have a few liters 50%
Check link below, Cheers
Hey! Noce vid, I tried it with my kettle and something weird happened. Some black stains appeared both at the bottom of the kettle and on the side (like splash dots on the sides) do you have any idea what this is or how to remove it?
I did soak a brass valve which got stained. But with the stainless stains where removed by the process and not the oposite. Sounds wierd. I don't have a clue what could have hapened. Hope someone will chime in here.

I believe it would be a low grade stainless. IE. high iron low chromium. You have rust spots eating through. Stainless steel scrubber or sanding down a bit then try to oxide it. If the spot goes all the way through, find a stainless welder and have them drill out and plug patch it.
How do you calculate 7% of citric acid to water? Is it by volume or weight? Thanks
A liter of water is 1000ml which weighs 1000g (the power of metric). So just as 70g of citric acid per liter if water.
@@DrHansBrewery thank you!!
Hello doc! Great video..I'll try this!! A question...could you start the next video with saying " Hello! I'm DrHans and this is DrHans Brewery my channel about beer and homebrewing, I eat spent grains for breakfast to keep my marvelous body in shape"!? Thanx in advance. Cheers!! 😝👍🍺
Thanks mate, I have some prerecorded videos comming up. Only the future will tell. Cheers!
What about the OUTSIDE of the pot, how does that get pasified?
Maybe you could continuously moistening it with a cloth or something like that if you would want to do that.
Your wort goes on the inside of the kettle, no need to do outside.
Hvor ofte bør man gjøre dette?
Beror väldigt mycket på. Men om du ser rostfläckar absolut. Om du skrubbat så att du kanske repat ytorna. Sen såklart beroende på hur mycket du använder grejerna. Kvaliteten på stålet. Ditt vatten osv. Du behöver iaf inte göra det ofta. En gång om året kanske på sin höjd.
They told me to use Trisodium phosphate (TSP) .
Rinse with water
Then Fivestar acid cleaner #5.
Rinse with water
Then Fivestar Starsan
many ways to skin a cat hi.
African Twin Ive heard several different ways to achieve the same goal. I’m sure that would work to. This is a more easy method and it works. What I didn’t mention in the video was that in the bottom of my sparge water heater. By the elements. There where rust marks, like a ring formed at the bottom. 30 minutes with this solution took that straight away. Now it looks like new again. I should have done this before.it was my new fermenter that got me to finally do it. Cheers and thanks for watching!
Hade ingen aning om passivering.
Rättstavningen gillar inte heller ”passivering”. 😀
Nu vet vi det med :D Skål!
Please use safety glasses guys.
Yes that's good practice. Should have done that!
