Q&A for How to Polish Marble

Avoid harsh and acidic cleaners, like vinegar, citrus, or ammonia, since they can damage the sealant on your marble and allow bacteria to leech into it.

You have to buff and refinish it. Vinegar stains happen from acid eating into the marble and then dust penetrating the "bald" porous surface. You have to make sure the top dust is buffed off and then seal the spot so that new dust doesn't accumulate in it.

If the scratches are very small and only on the surface, they can sometimes be buffed out with a soft cloth and a good cleaning.

No. Use a very fine steel wool #0000. Use a circular motion with steel wool to remove hard water buildup, then wipe with a clean water damp cloth.

Yes, use a silicone spray cover with a good coat and let dry for two hours, then polish with a camel cloth.

Use peroxide and baking soda. Make a paste, cover the entire surface and let it dry overnight. Then use a sift cloth and polish in a circular motion. You could also use a silicone spray when you're done to help it shine and protect it from staining.

You can put Lysol toilet bowl cleaner and one of those pumice sticks they sell at Wal-Mart for around $2, then wipe it all down with a magic eraser and it should be clean.

Polish, then seal. Sealer lives on the top of the surface, so if you seal first, then polish, you'll strip the sealer off.

Use newspaper or paper towels and a hot iron. Change the paper frequently until the wax is gone.

No, water won't be enough. You can use a mild dish-washing detergent (but not an acidic one).
