Alus Table Lamp

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.
Fabric shades are typically subjected to common cleaning maneuvers with vacuums or dusters, though they are easily dented, scratched or discolored. So it is important to clean them properly and carefully.
Usually in a fabric shade the softer material is wrapped around a plastic skeleton, so getting it wet is not a problem. However, if too much pressure is applied, they can easily dent and if sharp or metal objects are used, ripping and scratching can occur. So the cleaning has to be done with minimal pressure. Because this material is compatible with moisture, a kitchen sink or bathtub can make the perfect spot for cleaning. You can certainly do something more quick and simple to remove any surface dirt with a cloth or duster, but for a thorough cleaning, try some soapy water, light scrubbing and a gentle rinse to make it look like new again.
