Wax is an excellent furniture care product when applied over another finish. The wax creates a slick surface that resists scratches. But used as a finish, wax is problematic because it water marks easily. If any water gets on the surface, the wax will turn white and be difficult to fix. Unfortunately, removing the white mark isn’t as easy as applying another coat of wax or washing off the wax with a solvent. You have to scrub the surface with a solvent and steel wool or an abrasive pad.
