Fiberglass surfaces, like other surfaces, are susceptible to stains. From rust stains to soap scum, fiberglass attracts it all. There are several products you can use to clean fiberglass, including acetone--a chemical that is also used to remove nail polish and other paints. Acetone removes not only dirt and grime from your fiberglass surfaces, but also any set-in stains like rust and pen marks.
