Disinfecting Do’s

Before you disinfect your granite countertops, follow these tips for best results.

  • Make Sure Your Countertops are Sealed: Although granite is a very hard surface, weakly sealed or unsealed granite will soak up spills, stains, and oils. To make sure your countertops are sealed, leave a few drops of water on the surface. If the drops bead up, your seal is tight. However, if the water soaks into the granite, it’s time to reseal the stone.
  • Be Gentle: Always be mindful to use gentle dish detergent, warm water, and a microfiber cloth for daily disinfection wipedowns.

Disinfecting Dont’s

Granite countertops may be less porous than marble, but still avoid any abrasive and harsh sponges and cleaners.

Windex and acidic cleaning solutions like lemon, lime, vinegar, or anything with bleach or ammonia should be avoided. Frequent use of these harsh chemicals will weaken the stone’s seal over time.

Once the stone’s seal weakens or breaks, it will become extremely vulnerable to absorbing bacteria, stains, and spills. Therefore, be mindful that the harsher the chemical, the quicker your granite countertops will lose their seal.
