Tomoko Brown 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.
Use a feather duster, a clean soft white cloth or vacuum with a clean soft brush attachment as needed. For stubborn stains, clean the surface using a clean soft white absorbent cloth with a solution of mild soap and warm water. Wipe down surfaces with the damp cloth and dry with a clean soft white cloth. Avoid using glass cleaners, abrasive cleaning compounds, ammonia or bleach; they may damage the surface of the material and result in discoloration. Make sure cleaning materials are free of grit and other foreign materials.
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.
