Things You'll Need
Isopropyl rubbing alcohol
Granite is a very durable stone that requires low maintenance, making it an ideal material for countertops, shower stalls and tiles in homes and commercial buildings. It's important to properly care for and maintain granite to ensure its longevity and beauty. Using the proper cleaning agents will prolong the life of your granite. Acid-based cleaners will damage granite. Alkaline cleaners such as ammonia are also harmful.
Apply a small amount of isopropyl rubbing alcohol to a soft cloth. Isopropyl rubbing alcohol has a neutral pH level, meaning it is non-acidic and non-alkaline and will not scratch, etch or further stain granite.
Rub the moistened cloth over the soap stains on the granite. Work the cloth in a circular motion, allowing the alcohol to fully penetrate the stain.
Reapply rubbing alcohol to the cloth and wipe the soap stain until it is completely removed.
Dry the surface of the granite using a soft cloth.
Never use an abrasive or acidic cleaner or scrubbing pad on granite. Abrasive and acidic cleaners include Shower Power, Jif, Exit Mould Ajax and Comet. These cleaners will etch and further stain the granite, causing permanent damage.
