How to clean stain on cultured marble?
I left a potted plant on top of a cultured marble vanity top in a guest bathroom.
I went into the bathroom to tidy up today & lifted the pot only to see a round yellowish stain.
1) H20 with dawn = fail
2) Baking soda & vinegar = fail
3) Lysol bathroom cleaner with Hydrogen perioxide = fail
4) Mr. Clean cleaner = fail
Any other way to remove the stain without damaging the surface?
