My marble countertops in the bathrooms have turned quite yellow in spots. Any suggestions on how to get them clean again? I've tried everything from bleach to Zap. Please help.
I don't know the answer- but NEVER use vinegar or anything else acidic on real marbe (its ok on cultured marbe). It will actually etch the surface!

To remove stains from stone countertops make a poultice with diatomaceous earth and water adding the remedy below for the likely stain.
Rust - Iron Out Coffee and tea - Hydrogen Peroxide Ink, magic marker, etc - Methylene Chloride Oil - Ammonia or a degrease Paint - Mineral Spirits
They say the most important thing is to blot the stain quickly and not to wipe it because it can stain a larger area. Treat it as soon as possible. Marble is porous.
The link below has more information on stone care and refinishing. The article is written for stone professionals so is a little hard to follow. Hope this helps.
