Cleaners
It is always the safest bet to use cleaners that are specifically formulated for natural stone. They are ph neutral and are safe for all stones. Other household cleaners should be use for their intended purpose. Glass Cleaners are too harsh for some stones and too harsh for most sealers. Detergent soap will not hurt the stone at all. However, it will build up a film over time that is difficult to remove.

Spills
Don’t let spills sit too long. If you notice a spill blot it up. If a spill has dried up spray I with your stone cleaner and let it moisten and loosen the spill. Either scrape it with a single edge razor blade, or gently rub it with a plastic scouring pad.

For really stubborn spills use either denatured alcohol or acetone. These will not hurt the granite or marble. Wet a paper towel with either chemical and wipe the spill until it disappears.

Especially for marble vanity tops
When cleaning mirrors, spray the glass cleaner on the rag or paper towel rather than the mirror. The overspray from the glass cleaner could etch the marble.

Don’t put any wet bottle (perfume, after shave, hairspray) directly on the marble. Put your cosmetics and fragrances on a separate tray that has felt pads underneath it.

Marble Kitchen Countertops are increasing in popularity. Keep any acidic liquids off of the countertops. This includes fruit juices and alcohol.
