Put on your mask, gloves and eye protection. Remove the forced-air housing, grilles and vent covers with a screwdriver. Remove any ceiling diffusers. Place these parts on newspapers or rags that you can throw away later.
Mix 1 gallon water with 1 cup household chlorine bleach or 1 cup distilled white vinegar. Beware of splatters when working with bleach.
Wipe down all surfaces associated with the air vent with the bleach or vinegar solution, frequently soaking the sponge. Refill the bucket if the water gets too cloudy. Allow the parts to air dry for at least 10 minutes before replacing.
Pour the dirty water down the toilet, and flush several times. Seal the sponge in a plastic bag with the newspapers or rags the vent parts rested on, and discard.
