I have been using ProTeam Metal Magic. I noticed at walmart that they have something called Clorox Scale, Metal and Stain control. It is about $5 dollars a bottle cheaper. What I don't know if this is as good or will it work. It doesn't say on the bottle what is in it.
Clorox Scale, Metal and Stain Control MSDS

2-Butenedioic acid (2Z)-, homopolymer

Description of the goods : Corrosive liquids, n.o.s.

Does this mean anything to anyone?
