Wood paneling, despite being a vertical surface, needs periodic dusting. Regardless of the finish, vacuum paneling a few times a year using a brush attachment, or use a dusting wand to remove dust. Microfiber dusting cloths are well suited to removing dust without sending it airborne to be inhaled or settle on surfaces. If the wood is a bit rough and tends to snag the microfiber cloth, use a woolly dusting wand or even a broom wrapped with a damp towel.
Don’t clean waxed or unfinished surfaces with water, which may darken or stain the wood permanently. Be sure to dust these surfaces often, however, since wax, oil and commercial preparations tend to attract dust.
Wood wax should be re-applied at least once a year. When wax buildup becomes evident, strip the wax with turpentine and re-apply a fresh coat. Surface smears generally indicate excessive wax buildup.
Unfinished wood should be either oiled or treated with a commercial product, such as Scott’s Liquid Gold, at least twice a year. Use a soft, clean cloth to apply oil or product, and then use a second cloth to wipe up any remaining liquid.
