There are a few things you can do to clean a hair dryer before it needs to be serviced. First, unplug the dryer and empty the entire contents into the trash can. Second, take off all of the screws that hold the dryer to the wall. Third, use a vacuum cleaner with the hose attachment to suck all of the dirt and dust out of the dryer. Finally, use a hairdryer brush to clean any residual hair from inside of the dryer.
