Stone that has been acid damaged requires restoration using diamonds and polishing powders to bring the shine back.

Only professional services will render the shine back to pristine condition.

Acidic liquids attack stones likes marble, etching the finish of stone and taking the polish off.

Do note that vinegar is acidic too, and not to be used as a cleaner. Marble is a calcareous stone and sensitive to acidic cleaning. There's nothing you can do now.

A professional needs to come in, restore your floors, and re-polish.

Sealers in the stone industry are called impregnators because they impregnate the interior of the stone with silicones and resins that go through the pores of the surface.

Stone sealers do to stone what exterior wood sealers do to wood. They protect the interior of the material.

You absolutely must seal ANY natural stone tile including marble.

All stone is porous and WILL absorb liquids and can easily be stained by acidic items such as mustard, vinegar, wine and other foods and oils!

The shine on marble comes from a mechanical grinding, sanding and polishing process, and not from a topical product. The main objective of a "sealer" or impregnator is to protect the interior of the stone from staining. They help prevent fluids from penetrating through the pores.

Sealing is a preventive measure that provides extra protection to stone.
Impregnators will not prevent traffic patterns or scratches, nor will they prevent etching from acid spills on marble. An impregnator will keep the acid out of the stone but not off the top surface.

The old rule of thumb is never to use anything you wouldn't use on your hands.

Never use powdered cleansers or abrasive pads to clean your stone. Even "soft scrub" type cleaners contain pumice (powdered volcanic stone), which could damage your stone countertops or floors.

Never use any products which are acidic or alkali; this includes substances like ammonia or many common liquid cleaners such as Windex™.

This is one of the must common care concerns we are asked.

Stones are acid sensitive. Acid literally dissolves micro pits into the surface of stone. The result is that the flat reflective surface is now pitted and unable to reflect light properly.

As this is not dirt, but missing stone, cleaning it has little effect. The spots may appear to disappear immediately after cleaning, but re-appear as the surface dries.

Be aware, cleaning with an acidic cleaner will contribute to the problem.

There are two options to fixing this problem.
1. Marble Maestro offers a marble polish suitable to remove minor etches. A minor etch is defined as one that you can see, but cannot feel when you run your fingers over the etch mark.
2. If you can feel etches, you are going to need a stone craftsman to hone the damage and restore the stone surface.

YES. Ceramic and porcelain tile surfaces are much harder than your marble, limestone and travertine.

Stone surfaces are acid sensitive and will wear and abrade when dust and dirt are ground underfoot.

Granite surfaces are harder and with very few exceptions impervious to acids. However, proper care is still necessary. Unless you have been told this surface was resinated you will want to insure your surface is sealed every other year or so to maintain the surfaces' stain resistance.

NO. Marble Maestro use methods to trap dust and stone particles as they are removed from the stone.

We recognized long ago that maintaining a clean operation was important to our clients.
