Norma asked: How do I clean mold from the bottom side of a granite countertop? We have a condo on the Gulf Coast. The humidity is very high. Our air conditioning went out for two months while we were not there. I found mold on the cabinets, bottoms of drawers, and I think it is on the bottom side of my granite countertops. How do I clean this off? Will vinegar hurt the bottom side of granite countertops?
Most granite countertops are built on a sub-counter, which is typically made of plywood. On the odd chance that the underside of your granite countertop is exposed, this simple solution will safely clean mold from the surface.
You Will Need:
- Mold Cleaner
- Sponge or scrub brush
- Paper towels
Steps to Remove the Mold:
- Begin by spraying the Mold Cleaner directly onto the granite surface.
- Wait several moments to allow the cleaner time to work and break down the mold growth. Do not let the cleaner dry on the granite.
- Use a sponge or scrub brush as needed to scrub away the mold from the surface.
- Moisten soft cloths or paper towels with clean water. Wipe the surface clean with the damp paper towels.
- Dry the area with a towel.
Additional Tips and Advice
- If the underside of your countertop has mold on exposed wood, a solution of 1 part bleach to 3 parts water will safely and effectively eradicate the mold. Simply spray the solution onto the surface and wipe with a soft cloth. Wear eye and skin protection and work with fans or another type of ventilation, especially in small areas.
- To fully protect your countertops, do not use acids, including vinegar, to clean them.
