    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).)

    This is a must have for me to use for lowering my PH solution- one half teaspoon in 2 gallons of water and I’m good. -5.5 ph – I use this daily and recommend this to everyone
