Removing Rust Stains From Toilets, Tubs and Sinks

A pumice scouring stick works well for removing stains from porcelain. I don’t recommend it for fiberglass, but then there are not many fiberglass toilets I know of. With a pumice scouring stick like the made by United States Pumice Company, you simply wet the bar and rub it back and forth on the stain. You’ll develop a pumice paste which will assist in cleaning and polishing the surface, then simply rinse clean.
