The answer to 'why is my countertop dusty' is that countertops can become dusty for a variety of reasons, including poor cleaning habits, air quality issues, and natural wear and tear. Dust can accumulate on countertops due to factors like cooking, pet dander, and general household activity.
To address a dusty countertop, start by cleaning the surface thoroughly with a damp cloth or mild cleaning solution. Make sure to wipe down the countertop regularly, at least once a week, to prevent dust buildup. If the problem persists, you may need to consider improving your home's air filtration system or addressing any underlying issues that could be contributing to the dust.
