what a find, i was walking through the isles of a korean food specialty store and noticed these half full green glass bottles with a clear liquid in it. a few of them had even crystallized solid! on closer inspection (cant read korean though) i saw a small 99% on the bottle and bought it on a whim. got home and turns out its food grade glacial acetic acid! 2 bottles with aprx. 200-250ml cost me less than a dollar!! ill be remembering this. so if you have a asian food specialty store near by take a look around and see if you see this label...

I've been using the 25% I found at a korean store and it is pretty clean stuff - burns if you spill it.

Will keep an eye out for 99% although we got a bunch and I'm not sure what smells worse - GAA or DMSO?

I found 80% once.
Is it good for anything!?

For that price on the 25% stuff I suggest taking it and adding a bunch of salt to saturate the solution. Potassium Sulfate is the best IIRC in forcing the equilibrium but after adding the salt is added then you can extract the acetic acid with DCM. You can add a drying agent in this state and then distill off the acetic acid to give crystals of glacial acetic acid in the end. There will be some losses but it seems like your getting it rather cheep.
