Acid solution for Beerstone
« on: December 31, 2015, 04:23:23 PM »
Just wondering if anyone out there has a standard solution acid concentration for use in removing beerstone from brew kettles as mentioned by Drew Beechum on the most recent podcast?  Also, which type of acid do you use?

Any insight would be appreciated, as I have always done an overnight soak with PBW or Craftmeister in the past, but I understand the acid approach is quick and effortless.  I plan a New Year's Day brewery and keg cleaning and beer racking day.

No to high jack, but, I have a question about this also. Does Drew's method work for Aluminum kettles?

Drew mentioned citric acid in the show. I think the strength may be written on the container. He said low strength if I recall correctly.

John Blichmann told me that distilled vinegar is their favorite acidic cleaner for beer stone. I found that it works well. BKF works well too.

I've heard of people using Starssan at increased strength

I've used StarSan acid #5, and it worked OK.  Overnight with PBW works very well too. Craftmeister is OK. 

BKF is the best in my opinion.  And I scored on 4 cases (8 cans each)  of the large cans awhile back.  Believe it or not, Bed, Bath and Beyond.  Cheapest price, ($2 for 21 ounce) and since I bought so much, shipping was free. 

And of course a bunch of blue scrubbies

I have some stone in an old sanke and not sure what to do about it.  Probably just try a few things and see what works.  I know that professionally the solution is to follow certain protocol so that it doesn't form in the first place.  Anyone see issues with running bkf through a cip spinner ball?

I just learned something. BKF is manufactured in Indy. I did not know that prior.

I use Bar Keepers Friend in the liquid form. My local Home Depot carries it.

I use BKF and elbow grease, but I'm liking the distilled vinegar idea. May try that out shortly.

Is there a theoretical advantage to using bkf, considering that it is oxalic acid and beer stone is calcium oxalate?

Big advantage that like Nitric acid, oxalic acid will do a good job of passivating the stainless.

I read somewhere on this forum of someone using Star San sanitizer.     They used 1oz of Star San to 2 gals of warm water. This is a little over 2 times regular strength so use gloves and eye protection. I tried this on my Keggle MT and BK and it worked well, I was pleased with the result. Also I found using an old milk crate to lay them on the side and turning them periodically works well too. My valves and thermos fit inside the crate. cheers, Mike

you guys use BKF on the inside of kegs? I've always been scared to do that.

I use Acid #5 for my brewing system.  a recirculating loop seems to help it do its job best. 

would love to be able to use BKF for some items, however.
