Lacquer can be cleaned using an anti-static cloth or chamois leather cloth dipped in warm water or window washing solution. Whichever option you choose, clean the surface, then wipe lightly with a soft, cotton-fleece-type cloth. This method applies to both matte and glossy lacquer surfaces.
Avoid cleaning lacquer with a dry cloth, as dust deposited on the surface may become abrasive and damage the surface.
