Therefore, please read the care instructions below carefully, as damages to the surface and underlying material due to improper use are not covered by warranty. Do not use abrasive sponges or scrubbing products when cleaning. Additionally, we advise against using cleaners containing solvents or acids, limescale removers, household vinegar, and cleaning products containing acetic acid. These are aggressive towards the surface and will leave your product dull and scratched. Because the composition of commercial cleaning products often changes, we cannot guarantee that they will provide the gentle care our products deserve. Clean them only with a little soap and a damp cloth, then rinse and wipe them dry. You can avoid limescale stains by drying the products every time you use them. If limescale forms, remove it with GrohClean, our eco-friendly cleaning liquid. GrohClean has a special formulation that gently cleans the surface of our products
