The best maintenance for clear varnished wooden furniture is a coating of good paste wax. Paste wax is a very stable material that provides good protection from moisture and airborne pollutants.

Good quality paste wax is available in most hardware stores. A thin coat should be applied in accordance with the directions on the can. If brass hardware on the wooden furniture needs polishing, it is recommended that it be first removed from the furniture, so that the brass polish does not come in contact with the wood.

Between waxing, loose dust on the surface can be removed with a soft, lint-free cloth, gently rubbed over the surface. Dust is abrasive, and can scratch the surface, so care should be taken.
