It is important to protect wood pieces from sudden changes in temperature or humidity. Keep wood away from heat sources and the bleaching and drying effects of direct sunlight.To keep wood artworks clean, dust regularly with a brush or lint-free cloth. Some objects gain tremendous character over years of contact and use, but if you would like to keep the finish of your wood piece in pristine condition, handle it only with cotton gloves.
