We recommend using cleaning products between pH 5-8, as products outside this range may damage the surface. Avoid exposing Caesarstone to chemicals with pH levels outside this range, such as oven grill cleaners, floor strippers, toilet bowl cleaners, oil soaps, tarnish removers, furniture cleaners, drain products, etc. Should your surface accidentally be exposed to any potentially damaging products, rinse immediately with water to neutralize the effect.
