This is especially true for counter surfaces, where from wood to quartz to marble to granite, there are an incredible variety of surfaces you may be cleaning and disinfecting, each with its own unique personality.
For those of you with granite countertops at home, we’re excited to share insider tips on how to safely clean, disinfect, and protect your granite countertops to keep them ready for everyday use and looking great for the long term.
Better Seal Than Sorry
First off, before disinfecting, you’ll want to make sure your granite countertop is properly sealed. Granite is naturally less porous than many other stone surfaces, such as marble, though an unsealed countertop is more likely to soak up spills, stains, and even harbor unwanted bacteria . To test your granite’s seal, simply dribble some water on the surface. Does the water form into beads? Good, you’re securely sealed. If the water gradually soaks into the stone, though, you’ll want to have your granite resealed for proper cleaning and disinfecting.
To help preserve your granite’s seal over time, avoid cleaners that have vinegar or cleaners that contain ammonia or bleach, which can gradually weaken the seal’s integrity.
