Spring-cleaning tip: Take the time to go around the house and unscrew light bulbs to give them a good dusting. Built-up dust can be an economic hazard -- it limits the amount of light the bulb can emit, causing it to burn up faster than a clean bulb. The Environmental Protection Agency estimates a coating of dust on a light bulb can reduce light output by as much as 50 percent. So dust away!
