Granite countertops are a beautiful addition to any home, and you must properly care for and clean them to maintain your investment. Granite countertops have many benefits besides their beauty, such as scratch and heat resistance. Granite does need to be sealed to protect its surface.
Blot up spills immediately. Do not wipe up spills because this will just spread the potential stain.
Clean your granite countertop with stone soap, which you can find in most home improvement and hardware stores.
To remove coffee or tea stains from your granite countertop, use hydrogen peroxide and 2 or 3 drops household ammonia.
For milk, oil or grease stains, spread a paste of flour and hydrogen peroxide over the stain. Cover with plastic wrap and let sit for at least eight hours. Remove the plastic wrap and scrape away the flour mixture with a wooden or flexible plastic utensil to prevent scratching. This mixture will draw the stain to the surface. Repeat if necessary.
If you get an ink stain on your granite countertop, safely clean it with acetone (nail polish remover).
Never use anything abrasive like steel wool, scouring pads or scouring powders on your granite countertop. Do not use vinegar, lemon or orange as cleaners, nor bathroom, tub and tile or grout cleaners, as the acid can etch your granite countertops.
