Marble stain on vanity


Hi, I discovered a pale blue stain on the marble vanity top in my kids bathroom. My girls like cosmetics but I am wondering if it has been caused by leaking mouthwash as this is blue? They do not know what caused the stain. Do you think it can be removed? Many thanks!


Most stains can be removed from stone although not with typical cleaning methods. Stains are substances that get into the pores of the marble below the surface so standard rubbing and scrubbing won't cut it.

The procedure varies depending on what actually stained the marble, but you don't necessarily have to know exactly. You can experiment as needed until you find the right solution, but it is all spelled out with detailed step-by-step instructions in the Removing Stains Manual.

If it is mouthwash or any other acidic product, you may find that the marble has also been "etched," which is not a stain although mistaken for one very often.

Etching is a form of corrosion that occurs on marble, limestone, travertine and slate when in contact with an acidic substance or from too harsh cleaning products.

You have to get the stain out first, but once you do and if you find a dull and possibly lighter colored spot where the stain was, then you'll need to use ETCH REMOVER / Marble Polishing product to cure the problem and restore the shine.
