Granite can be cleaned with any mild cleaner such as warm water with dish soap. It is however preferred to use a specially formulated granite cleaner. If you are going to go with just plain soap and water, keep in mind that this can lead to soap build up. When using our granite cleaner, let it sit for about 30 seconds and then wipe it off well using a soft cloth. This will work best. Some granite cleaners also contain part sealer, which will help protect your countertops.
