How do u clean a bathroom fan?

Hi Joy,

You should be able to remove the cover to get inside. I can do that with mine. Then I use a vacuum to get out any dust, then clean the fan with any cleaner that you like. Just be sure that it's turned off before you start either by the switch or better yet, the breaker. Wishing you the best.

use a brush, hot water and sugar soap

I live in the Southwest with a lot of dust. Twice a year take off the cover - soak cover in a sink with hot soapy water. Vacuum out as much dust as possible. I use a stiff parts cleaning brush for those tough to get at places. Careful with the wires. make sure everything is clean. Scrub & rinse the cover & polish dry. Put cover back on & admire your work.
