Best way to clean fiberglass bathtub?
Hello, my shower stall and tub are both fiberglass. They seem to be getting dirty at the bottom where the texture is kinda of rough. I know I can't use a harsh chemical like acetone or scrub brush, it can take off the finish. Should I just buy fiberglass cleaner which I saw in the supermarket? Basically just want the tubs to stay white! I researched bleach and it said try not to use it, and if so, just for a short minute. We tried it and it didnt even work.
Help appreciated! :)
