Protecting your lamps may seems like a trivial matter. But maintaining it's cleanliness and preventing misuse of the light prolong it's lifespan. 

Always switch off your lights before you start cleaning

Use a feather duster to regularly dust lamps.

Wipe glass, ceramic, marble, or plastic lamps with a damp soft cloth.

Dry thoroughly before turning on power.

Do not use any harsh abrasives, polishes or chemicals.

To help preserve outdoor fixtures, a high quality car wax may be applied to the metal twice a year.
