We just had the upstairs bathroom redone and replaced the old fiberglass stall shower with a one piece acrylic one. It was done by a contractor and he didn't keep the data that came with it. I want to make sure I keep soap scum from sticking to the walls but don't want to use the wrong products on it. Was wondering if one of those spary shower cleaners that you hand on the shower head work. Last shower was fiberglass and after years of use it became impossible to keep the scum from forming.
