What can be used to Disinfect Granite Countertops?

Posted on Thursday, June 19th, 2014 by Govi Reddy

Granite slabs are proven to be very safe countertops material for kitchens, baths and other areas of homes and commercial establishments.

It is good to know that granite countertops are not a breeding ground for bacterial growth. The Center for Disease Control nor the Institute for Occupational Safety Control have found any evidence to show that granite countertops harbor bacteria.

Yet any countertop material, including granite, may harbor bacteria when they are kept moist and food debris is allowed to stay for long.

You can keep beautiful granite counters pristinely clean by disinfecting it with a solution that will not harm the granite or the sealant covering the top.

The process of disinfecting a granite countertop is simple and it can be inexpensive if you use a simple and effective cleaning solution that you make yourself.

Killing Germs

Mild dishwashing soap has antibacterial properties, which makes it ideal to use for disinfecting granite countertops. Make your own inexpensive countertop cleaner that will clean the granite surfaces safely and effectively.

Mix 4 tablespoons of isopropyl alcohol and 4 drops of dishwashing soap in a 1-liter spray bottle. You can purchase isopropyl alcohol in any grocery store or pharmacy chain. It is the same liquid used in first aid kits for small injuries. Fill the bottle almost to the top with warm water and shake the contents gently. Do not shake the mixture too vigorously because the homemade cleaner could lather so much that it won’t spray through the spray nozzle.

The Cleaning Process

Spray the cleaning solution onto the granite countertop, covering roughly 2 square feet of counter area. Allow the liquid to sit on the surface of the granite for about one minute to disinfect the counter.

Wipe off the cleaner with a clean, dry, white cloth to finish cleaning the area. Using a white cloth prevents possible stains from colored fabric. Repeat the same process until you clean the entire granite countertop.

Ingredients to Avoid

Avoid cleaners that contain vinegar or other acidic ingredients because these ingredients can diminish the shine of granite surfaces. Abrasive cleansers can harm the finish of a granite counter.

Do not use chlorine bleach, commercial window cleaners or other all-purpose cleansers on granite countertops. Check cleaner labels and do not use products containing hydrofluoric acid. These cleaners may harm the sealant or the granite itself.

Discouraging Bacteria

  • Disinfect granite countertops periodically if you cook in the kitchen every day.
  • Always use a cutting board when chopping or dicing food so food bacteria do not sit on the granite surfaces. This can be especially important in seamed areas of the countertop.
  • Wipe spills and messes when they occur. Leaving moisture on the granite surface could breed bacteria.
  • Maintain an effective sealant over the granite surface to act as a barrier for bacteria. Reapply the sealant once a year to keep the sealant adequate. Or you can use 3 year sealants like Stonetech Bulletproof Sealer.
