Dust and dirt can accumulate on the surface of your door over time, leaving unsightly marks and discoloration. Cleaning the door is easy, but the best method depends on the type of finish on your door. A simple wipe with a damp cloth is sufficient for most types of paint or varnish. However, if your door has a glossy finish, use a dry cloth to remove any dust or dirt. For wood doors, use a damp cloth, and work gently to avoid scratching the finish. For oiled or waxed wooden doors, you can apply paste wax or shellac to the surface and wipe it off with a damp cloth. You can also use a microfiber cloth to clean your door, although it’s less effective than a damp cloth for removing dust and dirt.
