What do you use to get beer stone out of a carboy? Pbw and brush didnt do it

I heard good things about Craft Meister Alkaline Brewery Wash. I haven't tried it yet, but going to pick some up on my next order. Supposedly works better than PBW.

I use this stuff from Micromatic. It does great things dissolved in hot water to remove beer stone from the inside of my kegerator lines.

I've never tried it on my carboys, I always use unscented Oxyclean in them.

Try an acidic solution. Beer stone is a stone, calcium oxalate the same thing that makes up kidney stones. Household vinegar may soften it up and if not buy oxalic acid from the hardware store.

Just curious, how did you end up with beer stone in a carboy?
