Cleaners such as strong acids and alkalis will cause irreparable damage to quartz countertops. For example, H₂SO₄ and NaOH. They will destroy the resin components of the quartz countertops and cause permanent damage to the surface of the countertops: color fading, loss of gloss, yellowing, cracks.

The resin of a quartz countertop can generally only withstand a high temperature of 150 degrees. When the temperature of a hot pot exceeds this limit, direct contact with the countertop may cause the resin to soften, deform, or even discolor, causing permanent damage to the countertop.
