Can I Use Bleach on Granite?

Using bleach on granite is not a good idea. Granite is a porous rock. It is typically covered by a protective sealant when you have it installed as a kitchen counter. This sealant protects the granite, ensures that your countertop is as stain-resistant as possible, and is food safe.

When you use harsh chemicals like bleach or acidic cleaners on your granite countertop, they erode the protective seal over time. At first, you may notice that your countertop looks cloudy and patchy.

It is not only harsh cleaning products that damage granite countertops. Did you know acidic foods like tomato, pineapple, vinegar, and oranges can also damage your granite?

If you spill any acidic food/drink on your countertop, be sure to clean it up immediately to avoid damaging the protective seal.

The same goes for cleaning products. Cleaning products with harsh chemicals or acidic properties damage the integrity of the protective seal. After using these products, you may find that the luster of your countertop is dulled. You may see cloudy or dull areas in place of your once shiny granite.

Worse yet, if these harsh chemicals sip into the granite, they can cause etching (discoloration and disintegration of the stone).

After a while, you may even notice dark marks or stains on your granite countertop. When this happens, it means that the integrity of the protective seal has been compromised, and your countertop likely needs to be replaced.

Other Cleaning Products You Should Not Use on Granite

  • Vinegar (or any other glass cleaner) that contains ammonia
  • Formula 409
  • Lysol
  • Windex
  • Pledge

The best way to clean your granite countertop is to use warm water and dish soap. Just a few drops of regular, mild dish soap go a long way in cleaning and disinfecting your countertop and leaving it sparkling.

To use dish soap, simply add one or two drops of mild dish soap to warm water and wipe the countertop with a clean rag using an “S” motion. Be sure not to use any abrasive sponges or steel wool when cleaning your granite countertop, as these products can damage the protective seal.

Rinse the suds off after cleaning and dry with a tea towel.

You can also use rubbing alcohol to disinfect your granite countertop. Ensure that the alcohol is 70-90% isopropyl. At this level of alcohol, germs stand no chance.

To disinfect your granite countertop, simply spray the rubbing alcohol, undiluted for maximum disinfectant power, directly onto the countertop. Leave it for around five minutes. Then, wipe the area with a clean, dry rag, and rinse with water. Dry the entire countertop with a dry tea towel.
