Whiten yellowed cultured marble.

Apply a mild soap or all purpose cleaner to the surface. You can spray the soap or cleaner directly onto your cultured marble or you can dampen a clean towel and wipe it over the surface. As it sits make sure that you keep the cloths damp but not dripping wet. White marble tiles can remain for years without yellowing then over time may slowly turn yellow and in severe causes may turn completely brown.

Pour the cleaning mixture onto the cloths and then allow it to sit for about an hour. This oxidation process is accelerated when the tile is saturated as in the flood in the above example. If the gel coating has worn down a bit the coating and cultured marble may become stained. This process of oxidation is similar to the rusting of metal.

This oxidation process is accelerated when the tile is saturated as in the flood in the above example. Areas underneath faucet fixtures or even objects such as a toothbrush holder may turn yellow if these. The best marble whitening method is to use a combination of a mild cleaning agent mixed with an absorbent material known as whiting finely ground white chalk which can be found in most paint or home improvement stores. Repeat the process as necessary until the yellowed cultured marble has been fully restored.
