    I was looking for something that would dissolve soap scum and figured that citric acid would work. I bought 5 pounds – far more than I needed – because it was so cheap. It came in a resealable plastic bag that actually resealed. It did a pretty good job dissolving soap scum. (I dissolved it in water in a spray bottle to use. Note that citric acid is not poisonous but in concentrated form is an irritant – rinse it off if you get it on you. In dilute form it is harmless (citrate is part of the citric acid cycle the body uses to metabolize food).)
