I have acquired an old used keg that is in good shape except for what I believe are some Beerstone deposits on the bottom.
I've tried long PBW and StarSan soaks to no avail. I cant reach the bottom because of my fat arms but SWMBO was awesome enough to try scrubbing for me and confirmed that it seemed hard and wouldn't budge for her.
I've read some folks talking about using a hot vinegar soak with mixed feedback but I haven't tried that yet myself. The most assuring thing I've read about is FiveStar Acid #5 or #6 which is caustic and hard to find for the homebrew scale.
So, just wondering if anyone has tips I haven't read yet and/or knows of better sources for the FiveStar acids. I can find gallons for sale online but for the cost including freight I could just buy another used keg and scavenge this one for parts.
Thoughts?
