Wipe clean with a soft cloth dampened in water and a mild washing-up detergent or soap, if necessary. Wipe dry with a clean cloth. Do not place a toaster, coffee maker, kettle or other kitchen appliances that emit heat directly over a seam between two worktops because the heat can damage the seam. To prevent permanent stains on the worktop, wipe clean spills or messes immediately with a soft cloth dampened in water and a mild washing-up detergent or soap.
