The answer to 'why is my countertop buildup' is that countertop buildup is a common issue caused by a combination of factors, including food spills, mineral deposits, and general wear and tear over time. This buildup can make your countertops look dingy, discolored, and difficult to clean.
Some common causes of countertop buildup include: 1) Food and beverage spills that are not cleaned up promptly, 2) Hard water deposits that leave behind mineral stains, 3) Grease and oil accumulation from cooking, and 4) Scratches or etching in the surface that trap dirt and grime. The symptoms of countertop buildup include a dull, cloudy appearance, sticky or tacky feel, and difficulty cleaning the surface.
