Hard water, rust and soap residue can leave stubborn stains on porcelain pieces that can be difficult to remove, even with harsh chemicals. Pumice stones are lightweight, palm-sized volcanic rocks used as a gentle abrasive to clean surfaces or in cosmetic applications as an exfoliant. Although using a pumice stone on delicate surfaces, such as porcelain sinks and tubs, may appear to be a bad idea, pumice stones are actually quite gentle and easy to use. The key to cleaning household surfaces made of porcelain with pumice is to keep the stone wet.

Soak the pumice stone in water for at least 2 minutes. Soaking the stone softens it and prevents it from scratching the item's surface.
Rub the pumice stone over the porcelain, applying light pressure as you do so. The pumice stone will sound loud against the porcelain.
Wet the pumice stone periodically as you use it. Dry pumice stones are more likely to scratch porcelain and other surfaces.
Rinse the porcelain with clean water. Look closely at the porcelain to determine if any stains remain. If so, scrub the finish lightly with the wet stone until all of the marks are gone, then rinse well.
Tips and warnings
- Rubber gloves are not necessary, but they can protect your hands from germs and make it easier to grip the pumice stone.
- Do not use abrasive cleansers with a pumice stone. The combined abrasive properties of the pumice stone and an abrasive cleaning product will scratch the porcelain.
