If you have star-san sanitizer on hand just mix up a double strength batch and soak them in that. I use this on my SS fermenter bucket too. Beer stone needs acid to remove.
Thanks for the input. I stopped at Ace Hardware this afternoon. Item wasn’t in store. They were not able to order as delivery status was “ETA (blank)”. Person working at Ace Hardware said this indicates “unknown” when available. Also, I would have had to order 4 bottles.
Another way to remove it that is cheaper than Star San is to get an acid cleaner that is used for dairy equipment from a farm supply store. The one near my house that sells and services bulk milk tanks has a product that contains Nitric, Sulfuric, and Phosphoric acids. I use about 15 ml of the stuff in 5 gallons and soak for about 15-20 minutes. It cleans up my boil kettle and kegs quite nicely. If you are sticking with Star San you will need about one ounce per gallon of water (this is what SS Brewtech recommended for their conical fermenters).
Remember though, you have to clean the keg with PBW, Craftmeister, or caustic before doing the acid soak to remove any organic soils. The acid won’t remove these, only the inorganic beer stone.
Didn’t seem unreasonable at $14.50 per gallon. Yes, ACE has the better prices at $12.99 a gallon, but I was unable to find.
Then, on Tuesday, November 16, 2021 I receive an email from Magellan Distribution Corp telling me the website is wrong and I will only receive 1 bottle and NOT the 4 bottles for $58.00 that I ordered. THIS IS ILLEGAL and dishonest.
I immediately contact Walmart to let them know, once again, this is illegal and dishonest.
Order canceled, but now I’m looking again to find the milkstone remover.
BTW, I tried BLC in the corny kegs. Didn’t remove the beerstone.
I tried looking it up on their website and get no results [emoji2369]. I had to order it and pick it up at the local store. Not sure why they don’t list it anymore.
The only thing about Barkeepers Friend is that it is a bit abrasive. I don’t use it in kegs or my fermenters because to the possibility of scratching the stainless steel.
