    "You saved our travertine floor! The installation was so poor, we thought we would have to tear it out. Your ability to grind, regrout, and polish the floor surpassed our expectation. Now it looks like it should have looked after being installed – the sheen is even and reflects the wonderful richness of the stone. It's gorgeous!"

    We only use sustainable methods in the restoration of stone surfaces.

    Nothing compares to the elegance and beauty of natural stone. Yet many property owners don’t know how to care for marble floors, granite counters and other natural stone surfaces. But there’s good news! With a little effort – and the proper care – your natural stone will give you decades of low-maintenance service.

    Here are answers to some of our most-asked questions. If you don’t see your question answered here, visit our Ask the Expert. Simply post your question, and we’ll provide an answer as soon as possible.


    How should I clean my kitchen countertop and vanity surface?
    Clean your countertops daily with a soft cloth or paper towel and a residue-free cleaner designated safe for natural stone. To remove streaks, buff the countertop with a clean white cloth or paper towel. Also, you can apply a good stone polish to the surface of your countertops for additional luster on special occasions.

    How should I clean my marble or natural stone floor?
    The #1 culprits are dust, grit and sand, due to their abrasiveness. Therefore, frequently vacuum interior floors to lift the dirt and grit off the floor – every day, if possible. Dust mopping with a clean, non-treated, dry dust mop or microfiber cloth tends to push the dirt and grit into the grout lines as opposed to removing it. Use a damp mop every week. Place mats and area rugs at entrances to catch dirt and minimize scratches. Do not use vacuum cleaners that are worn, because the metal or plastic attachments may scratch the surface. Also, be sure to immediately mop up spills!

    How do I treat stains on kitchen and bathroom counters?
    If possible, immediately blot spills with a clean paper towel. If the liquid has soaked into the stone and stained it, you may need to apply a poultice to treat that specific stain on your specific stone surface. Not all over-the- counter stain removers will work on all stains and stone surfaces. Contact Don Semi for specific instructions.

    Will my entry rug harm my stone floor?
    Rugs are a good idea to catch dirt and grit. Please keep these points in mind: Use non-slip mats under rugs to keep them in place. Sliding rugs are dangerous, plus they are a constant source of scratches from sand and grit. Do not use rugs that are backed with rubber or latex.

    How can I restore the original shine and luster to my floor?
    Now is the time to call Stone Restoration Denver. If your floor or other surface is not deeply scratched, surface polishing may bring back an acceptable shine. If your floor has worn badly, a complete restoration is warranted. If your kitchen or bathroom granite countertops are no longer shiny, you may have a surface film from a buildup of soap. We can schedule an onsite visit to evaluate your natural stone surface and discuss the best cleaning and polishing strategy.

    How much dust is created during the restoration process?
    There is no dust created during the restoration process, because we use diamond abrasives and water.

    How should I clean the stone in my bath/shower?
    In the bath, shower or other wet areas, you can minimize soap scum build-up by using a squeegee after each use. Using a soap film cleaner along with the squeegee is encouraged.

    How should I clean my pool and patio area?
    In outdoor areas with a pool, patio or hot tub, flush the natural stone floor with clear water. Use a mild bleach solution to remove algae or moss.

    What are your favorite tips for general cleaning?
    The most important tip is to clean your stone surface with a cleaner designated safe for natural stone. Never use products that contain lemon, vinegar or other acids on marble, travertine, limestone or onyx, because these products can etch the stone’s surface. Do not use scouring powders or creams, because these products contain abrasives that may scratch the surface.

    • Mop floors frequently. Use a clean mop on floors and a soft cloth for other surfaces. Change the rinse water frequently.
    • Clean surfaces with a neutral stone cleaner. Never use more than the recommended amount; too much may leave a film, causing streaks.
    • Thoroughly rinse and dry the surface after washing.
    • Blot up spills immediately.
    • Protect floors with non-slip mats or area rugs.
    • Protect marble countertops with coasters, trivets or placemats, particularly under glasses or containers of alcohol or citrus juice. (Many common foods and drinks contain acids that will etch or dull the stone surface.)
    • Don’t place hot items directly on the stone surface. Use trivets or mats under hot dishes and placemats under china, ceramics, silver or other objects that can scratch the surface.
    • Don’t use cleaners that contain acid such as bathroom cleaners, grout cleaners or tub-and-tile cleaners.
    • Don’t use abrasive cleaners such as dry cleansers or soft cleansers.
    • Never mix bleach and ammonia. This combination creates a toxic and lethal gas.

    How can I remove the dull spots from spilled vinegar on our marble floor and bring back the shine?
    Marble is a calcium carbonate. When an acidic substance like vinegar comes in contact with marble, it causes a chemical reaction called etching. Natural stone sealers penetrate the stone but cannot prevent this natural reaction. If the stone is etched, we can polish and refinish it.

    How can I remove water spots on my marble or travertine?
    These are not water spots, but an etch mark in the surface of the stone. This is what happens when an acidic substance comes in contact with a calcium-based stone. To remove the etch marks, the stone will need to be polished, like removing a scratch from a gemstone. If the etch mark is minor, you can first try polishing it yourself using a quality marble polishing compound. If the etching is more severe, you will need to have it professionally serviced.

    How often should my stone surface be sealed?
    Your natural stone and grout may need to be periodically sealed. For small jobs, you can purchase the product and do it yourself, or contact us to perform the service for you. Countertops may need to have a penetrating sealer applied. If a sealer is applied, be sure it is nontoxic and safe for use in food preparation surfaces.

    Can you clarify some terms?
    For example, what is the difference between grinding, honing and polishing?

    • Grind: Remove deep scratches and lippage (uneven edges), using a machine with diamond abrasive pads and water. This process creates no dust.
    • Hone: Use a machine with diamond abrasive pads and water to remove minor scratches and wear from daily foot traffic. This process creates no dust.
    • Strip: Remove coatings that block the stone’s ability to breathe and often cause spalling (areas in which the stone cracks and large pieces pop off). Coatings include crystallization, janitorial waxes and polyurethane.
    • Clean: Remove dirt, stains and bacteria and remove waxes and polymers that have become embedded.
    • Polish: Give the marble, granite or other stone surface the sheen you want, enhance the veining in marble, and protect the stone from everyday traffic and spills by using the same compounds used in the manufacturing process.
    • Seal: Protect and preserve natural stone using a penetrating sealer, also called an impregnator.
    • Color enhance: Enrich and enhance the stone color using penetrating sealers/impregnators.
