Q. I have a white stain on my marble vanity top. I've tried everything and I can't remove it. Help!
A. What you are describing is not a stain but an etch. Etching can occur on marble and other calcite based stones when acidic liquids interact with the calcium in the stone. The acids have actually etched away a fine layer of the stone's surface, leaving behind a dull, sometimes rough area. Just like with a diamond or other gemstone, when the surface is damaged, it needs to be polished down to the level below where the damage is. If it is a minor etch, there is a great product for this. Etch Remover Marble Polishing Compound was created just for this purpose.
Q. How do I know when it's time to reseal my stone countertops?
A. There is a simple way to test if your countertops are due to be sealed. Spill a few drops of water onto the counters and let it sit for a few seconds. Wipe the water away and if after a couple of seconds you see that the area where the water was has darkened, indicating that the water penetrated below the surface, it's time to re-seal.
Q. I have mold and mildew on my grout lines in my shower. How can I safely remove it?
A. Mold and mildew growth is a very common problem on grout lines in damp areas. For routine cleaning of mold and mildew stains, use Majestic Mold and Mildew Stain Remover. If the staining is very severe, or it has been there a long time, you may want to create a poultice to remove the stains.
