Can i use acetone on fiberglass pool step?

Using acetone on fiberglass pool steps is not recommended, as it can damage the gel coat and the surface finish of the fiberglass. Acetone is a strong solvent that can cause discoloration, dullness, or even structural damage to the pool steps. Instead, consider using a mild soap solution or a cleaner specifically designed for fiberglass surfaces to safely remove stains or residues. Always test any cleaning product on a small, inconspicuous area first to ensure compatibility.
