Use a blast of canned air to quickly clean dust from the wall and ceiling grilles of vent fans and heating/air conditioning systems.
By the DIY experts of The Family Handyman Magazine:November 2005
Blow the dust from wall and ceiling grilles with short blasts of canned air. Make sure the fans are running when you do this.
If the grille on your bathroom
exhaust fan is clogged with dust, try
a trick that's faster and more effective
than vacuuming: Turn on the fan
and blast out the dust with "canned
air." The fan will blow the dust
outside. This works on the return air
grilles of your central heating/cooling
system too. Run the system so
that the return airflow will carry the
dust to the filter. You'll find canned
air at home centers and hardware
stores, usually in the electrical supplies
aisle. Caution: The cans contain
chemical propellants, not just air.
Don't let children play with them.
