Use a ph neutral cleanser and a soft cloth. Don’t use harsh cleansers or scrubbers. While granite is very durable, acidic cleansers and sponges that can scratch will wear down a sealant. Use ph neutral soap to clean your countertops and steer clear of Windex or vinegar. Stone cleaner works as well as simple dish soap.
Wipe the top down regularly. Keeping the surface free of dirt and grime will help preserve granite. Clean your countertop regularly with warm water and a few drops of dish or antibacterial detergent using a soft cloth. Rinse the surface thoroughly with clean water and dry with a soft cloth.
Blot spills up immediately. If you spill something on the surface, blot with a paper towel or soft cloth right away. Do not wipe spilled liquids, like juice or milk, because this can spread them around your countertop. Dry any spilled liquids with a dishcloth. Granite countertops and properly sealed stone will repel most stains if the spills are cleaned promptly. Use a dry, dishcloth to dry your granite after any spills, so moisture does not seep into the pores of the stone.
Do not put hot pots or pans on granite. Hot cooking pots will not damage the surface and granite can withstand high temperatures, but extreme or constant temperature changes can harm your stone. For instance, avoid leaving hot pans sitting on granite in a chilly room.
Use coasters under cups or liquid-filled pots. Protect your granite from moisture absorption by using coasters under anything filled with liquid. Be especially careful with dark colored liquids, like red wine or juice.
Use baking soda and water on oil marks. If you spill oil-based liquids on your granite, like milk or grease, you may need to remove some stains. Make a paste out of baking soda and water, slather it on the oil marks, cover it and let it sit for several hours or overnight.
Use baking soda and hydrogen peroxide on water-based marks. Coffee, juice and wine may leave marks if it’s not cleaned up immediately and penetrates the stone. Add just enough hydrogen peroxide to baking soda to make a paste. Apply it to any water-based stains or marks, cover it and let it sit overnight.
Disinfect with water and alcohol. Granite naturally repels bacteria, but if you want to disinfect your countertops more than what soap and water can, use water and 91% isopropyl alcohol. Mix the solution up with a 50/50 ratio, spray it on the countertops, and let it sit for three to five minutes. Rinse with water and dry with a soft dishcloth.
