How to Clean a Marble Tub
Marble tubs are manufactured from crushed limestone and polyester resin. A gel finish coats a marble tub to produce a durable, transparent surface, which is resistant to normal wear. Marble tubs resist stains due to their non-porous surfaces, but they still need to be frequently cleaned to remove soap scum and dirt. Properly cleaning a marble tub is necessary for maintaining the tub's surface. Never use harsh abrasive cleaners, as they can damage the surface of the marble tub.
