Most countertop surfaces wipe clean with a soft cloth and a mild solution of soapy water for normal wear. Scratches and stains are more difficult to remedy and sometimes will require the services of a professional. Be sure to go over care and cleaning of the countertop with your salesperson at the time of purchase. If your countertop surface is synthetic (as opposed to natural stone), there is generally some kind of warranty provided by the manufacturer as well as care instructions.
