mike , it's used for cleaning the equipment . mixes 1oz to 6 gals of water for most use. at 12 bucks a gal it is pretty cheap. i looked at it a few years ago . on the gal jug it states 56.33% so it is pretty strong right out of the jug. i dont use it all the time but on some stubborn places it works pretty good . phosphoric acid is pretty weak to start with .
