I have these 2 growlers that I'd like to use to ferment small batches of cider and mead...and whatever else will make bubbles if I put yeast in it. They have some crusty crap on the inside that I cannot get out for the life of me. What I have tried so far...and am willing to try again.
1. soaked with PBW and scrubbed. It got a lot of that crud but left the hard water stains and a bit of the shmegma on the walls.
2. soaked with star san - it got the hard water crust off but I still have that crap on the walls.
3. prayer. no effect.
I will take any tip you have. I don't want to toss these things. Is there some acid/caustic/anti-crud juice that will definitely get that glass clean?
Thanks amigos!
