Dirty light fixtures can emit up to 20% lesser light than clean ones. So regular cleaning and dusting go a long way toward brightening your living spaces.
For safety purposes, never attempt to clean or work on a lighting fixture with an active electrical current. The best bet is to unplug fixtures or turn off the circuit breaker prior to cleaning. Also, never allow liquid to touch wiring.
Dust with a slightly damp, soft, lint-free cloth. Once a month ,clean the surface with a clean soft cloth dampened with a quality cleaner formulated for wood furniture. Wipe dry with a dry, soft cloth in the direction of the wood grain. Also, do not use polishes containing waxes or abrasives or polishes that are oil based. For minor repair of water rings, stains, and scratches; rub the surface lightly in the direction of the wood grain using steel wool. Apply a scratch-removing polish with a color and value that simulates the wood color if required.
