Metal or porcelain lighting should be cleaned with a soft, dry cloth or duster. Never spray fixtures with a cleaning solution or polish. If it is necessary to use a cleaning agent, please apply only a mild detergent to a soft, damp cloth for gentle cleansing. DO NOT use scouring agents, abrasive sponges, hydrochloric acid, vinegar, ammonia, petroleum distillate or metal silicates. Shades should be dusted on a regular basis with a soft cloth.
