Q.We have cultured marble vanity tops in all of our bathrooms. It seems as if when you place something on these (e.g. soap dish, tooth brush holder, etc) that after a period of time the marble under these items becomes discolored; takes on a yellowish color. Is there something we can use to clean this that will remove these discolored spots ?

A. Cultured marble may have a gel coat on the surface that is failing. You need to call a cultured marble pro.

You could try to find one in your area at the below web site. They should be able to help you.
