How to Clean Granite

There are many ways to clean granite countertops and keep them looking shiny and brilliant. Just avoid using cleaners that are too harsh; they can damage the sealant and dull the finish. Here are some simple steps to clean your granite surfaces and restore their shine.

Cleaning Soiled Granite

You Will Need:

  • Soft cloth or sponge
  • Bucket or large bowl
  • Neutral dishwashing liquid
  • Warm water
  • Microfiber cloth
  • Natural stone or granite cleaner

The Cleaning Process:

 

  1. Add a few drops of dishwashing liquid to the bucket or large bowl of warm water, working it until suds form.
  2. Wet your sponge or cloth with the soapy water and wipe the soapstone surface thoroughly.
  3. Rinse out your sponge or cloth with plain hot water and wipe away any sudsy residue from the soapstone surface. If you have streaks and a dull finish, it may be because there is still soap residue on the surface. Rinse the sponge or cloth again with hot water and wring it out thoroughly to remove most of the excess water. Wipe over the surface again to remove any residue.
  4. Wipe the surface dry with a microfiber cloth.
  5. Periodically clean your granite surfaces with a natural stone or granite cleaner to restore shine. Products such as Granite Gold are available at grocery stores, department stores, hardwares and home improvement stores.

Removing Stains from Granite

Granite is a porous stone, so time is of the essence when it comes to removing stains. Blot at the stain rather than rubbing it to avoid spreading the stain. The longer a stain sits, the more likely it is to soak in and will be nearly impossible to remove. Here is one removal technique that will work for several common stains.

You Will Need:

  • Powdered whiting product such as Talc (available at paint and home improvement stores)
  • Hydrogen Peroxide
  • Water
  • Plastic wrap
  • Tape
  • Small bowl
  • Clean cloths or sponge
  • Microfiber cloth

The Removal Process:

  1. Poultice is made to absorb the stain out of the granite, but it will take time.
  2. Begin by mixing the poultice (powdered whiting and hydrogen peroxide) according to manufacturer’s instructions in the small bowl. You will want to create a thick paste. It should be the consistence of putty.
  3. Apply to the stained area, keeping it only on the stain. The layer of paste should be about one fourth of an inch thick and overlap the stain about a half an inch.
  4. Cover the area with plastic wrap and tape the edges down.
  5. Allow this to set on the stain until it’s dry. This can take up to two days.
  6. When the paste is completely dry, use a cloth or sponge to wipe away the paste.
  7. Rinse with clean water.
  8. Clean the area as normal and allow it to dry.
  9. If the stain remains, you may need to repeat steps 2-6 several times, each time removing more of the stain.

Additional Tips and Advice:

  • Granite is very hard and scratch resistant. If you do have a scratch, it is best to have it repaired by a professional.
  • Use coasters under all glasses to prevent stains on your granite surfaces.
  • Avoid letting citrus or alcohol products sit on the granite surface as it can etch and dull it.
  • Keep hot items off of granite; always use a trivet or hot pad for protection.
  • Resealing your granite will help to preserve it and keep its shine. This is typically done approximately every 2 years.
  • If you want to make your own pH balanced cleaner, try mixing 1 part water with 1 part alcohol (or less if preferred)
  • If you have granite flooring, it’s best to clean it with granite cleaner or have a trained professional clean it. For daily maintenance, sweeping and dusting is usually sufficient.

    I have white wine stains on my new Star Galaxy granite worktop. These are in the form of rings from the bottom of the glass and one small patch that I think a glass may have been knocked over. I did not realize that wine could damage the granite. This was about three weeks ago. Is there anything that I can do to repair this, or is it permanent?
    Thanks,
    Jane

    Hi, I left a candle on my kitchen bench, which is either granite or caesar stone, and it has now left two mug-sized marks. The candles were never lit, but were sitting in the same place for several months. How do I remove these marks? Thank you.

    I just had a new granite counter top installed, and noted that there is a small area of the counter top that looks dull. When you run your hand over it, it has a different smoothness to it than the rest of the surface. We did not notice this after it was installed. Is this stone damage? What else could it be?

    I have installed exterior granite panels and the joints were filled with silicone sealant. The installer tried cleaning the sealant with the recommended solvent, but the sealant and solvent left smears that attract dust. Everywhere the sealant was cleaned off, dust collects. I clean it and it is back within hours. Any suggestions on how to rid this problem?

    How do I remove candle wax marks from my granite fireplace?

  15. Melanie says:

    Pat,
    It is usually the colorful dyes within the wax that leave a stain. Try the poultice for dye stains mentioned in this article: How to Remove Stains from Granite. The How to Remove Candle Wax Stains article recommends rubbing alcohol, so I would use that for the poultice.

    While painting the house, paint drops fell all over our kitchen platforms laid with granite stones. This is looking absurd. Please inform how to remove paint stains without there being scratches on the granite platform.

    K.V.,
    This article might help: How to Remove Stains from Granite Countertops. Rubbing alcohol is more similar to paint thinner than hydrogen peroxide, so you may want to use the alcohol first.
