The answer to 'when to clean countertop' is that you should clean your countertops on a regular basis, typically 1-2 times per week. Cleaning your countertops helps maintain their appearance, prevent the buildup of dirt, grime, and bacteria, and ensure a hygienic food preparation surface. The frequency of cleaning may vary depending on the amount of use and the type of material your countertops are made of.
For example, granite and quartz countertops may only need a quick wipe-down with a damp cloth or a mild, pH-neutral cleaner 1-2 times per week. Laminate or solid surface countertops may require more frequent cleaning, as they can be more prone to staining and discoloration. It's also important to clean up spills and messes as soon as they happen to prevent the buildup of stubborn stains or the growth of bacteria.
