Soap scum makes me nuts. It's right up there with dust. It's a never ending job with little reward, I tell you! I have bought many expensive toxic chemicals trying to annihilate the scum, and again with little reward.
Jen at Life Crafts and Whatever had a solution. I have vinegar and Dawn so let's give it a try!
My results: pretty good. Not the life changing event I was hoping for, but pretty good. And I'll do it again because the results were as good or better as the expensive toxic cleaners I've tried before.
