Here's how to clean various countertop materials:  Granite: Use liquid dish soap, warm water, and a soft sponge to wash granite countertops. Apply rubbing alcohol periodically as a disinfectant.  Quartz: Clean up spills quickly to avoid staining. Wash daily with soap and water. Use Windex and a nonabrasive pad for tough jobs. Soak for 10 minutes, if necessary. Remove grease with a degreaser that's safe for quartz.  Marble: Protect marble surfaces with monthly applications of spray sealant. Apply sudsy hot water with a sponge or soft cloth for routine washing. Use mild soaps or detergents.  Formica: Dish soap, Windex, baking soda, and mild household cleaners are safe to use for washing Formica countertops. A microfiber cloth works best. Clean seams with a soft toothbrush.  Wood: Wash butcher block countertops with soap and water immediately after use. Apply mineral oil monthly, and avoid vinegar.
