Switch the power off at the breaker and let the bulbs cool for at least 15 minutes. For routine care, dust each arm and crystal with a dry microfiber cloth every 4 to 6 weeks. For a deep clean once or twice a year, mix one part isopropyl alcohol to three parts distilled water, mist the cloth rather than spraying the fixture, wipe each crystal and dry immediately to prevent water spots. Never use ammonia, vinegar or abrasive cleaners on gold, brass or plated finishes.
