The way to clean a Lasko space heater would be to take a vacuum with the brush attachment
on the hose and vacuum the intake and exhaust vents of the heater from the outside without opening the unit. We advise that the unit is not opened in any capacity as doing so can void the warranty. If the unit is still not clean, you can take a can of compressed air and blow in the exhaust vent of the unit from the outside and then vacuum the intake vents to pull the dust out.
