Use recommended cleaning products and check the product first by applying it to an inconspicuous area on the surface. It’s best to avoid using the same cloth you use for washing dishes, as it may transfer oils and other contaminants to your surface.
Cleaning products that should not be used, include oven grill cleaners, floor strippers, toilet bowl cleaners, oil soaps, tarnish removers, furniture cleaners, drain products, wipes and cleaners specific to granite, marble and other natural stones, etc. Should your surface accidentally be exposed to any potentially damaging products, rinse immediately with water to neutralize the effect.
