Mild dishwashing soap has antibacterial properties, which makes it ideal to use for disinfecting granite countertops. Make your own inexpensive countertop cleaner that will clean the granite surfaces safely and effectively.
Mix 4 tablespoons of isopropyl alcohol and 4 drops of dishwashing soap in a 1-liter spray bottle. You can purchase isopropyl alcohol in any grocery store or pharmacy chain. It is the same liquid used in first aid kits for small injuries. Fill the bottle almost to the top with warm water and shake the contents gently. Do not shake the mixture too vigorously because the homemade cleaner could lather so much that it won’t spray through the spray nozzle.
Avoid cleaners that contain vinegar or other acidic ingredients because these ingredients can diminish the shine of granite surfaces. Abrasive cleansers can harm the finish of a granite counter.
Do not use chlorine bleach, commercial window cleaners or other all-purpose cleansers on granite countertops. Check cleaner labels and do not use products containing hydrofluoric acid. These cleaners may harm the sealant or the granite itself.
