Most people don't realize how easy it is to keep mirrors clean, and one expert says a little-known but effective way is to use a feather duster once or twice a week.

Lou Anne Kellman, vice president of Globe Mirror Design Group, a division of one of Chicago's oldest glass companies, offered the following tips to keep mirrors bright.Mirrors attract dust because of the static charge on the surface of the mirror which acts as a magnet, and the dust in turn attracts grease, dirt, pollen and tobacco smoke.

"If you use a good quality feather duster, the feathers have a strong static charge, so they pick up the dust magnetically, leaving no oily residue," said Kellman.
