The answer to 'how to maintain countertop' is to regularly clean and care for your countertops to keep them looking their best. This involves wiping up spills immediately, using the right cleaning products, and protecting the surface from damage.
Start by wiping down your countertops daily with a damp cloth or sponge to remove crumbs, spills, and dirt. For a deeper clean, use a mild soap and water solution or a countertop-specific cleaner a few times per week. Avoid harsh chemicals or abrasive scrubbers which can damage the surface. When possible, use cutting boards to protect the counter from knife marks and scratches. Periodically seal natural stone countertops to prevent staining and wear over time.
