Do not use citrus based cleaners, you can damage granite counter tops. Do not use Windex it will strip the seal off the stone. Mix 1/4 cup of rubbing alcohol, or cheap vodka, and 3 drops of dish soap, into a 16 oz. spray bottle then fill the rest with water, and shake. It will give counter tops a nice shine. This cleaner also works on appliances.
