The answer to 'how often to clean countertops' is that you should clean them daily or at least a few times per week. Countertops accumulate spills, crumbs, and other debris from food preparation and everyday use, so regular cleaning is important for maintaining a clean, hygienic kitchen. Wipe down countertops with a damp cloth or paper towel after each use to remove any immediate messes. Then, do a more thorough cleaning 2-3 times per week using a mild soap and water or a dedicated countertop cleaner.
Proper countertop cleaning helps prevent the buildup of bacteria, grime, and stains that can be difficult to remove if left too long. It's also a good habit to give your countertops a deep clean once a month using a disinfectant solution to kill germs and sanitize the surface.
