The screen on your hair dryer is designed to catch dirt, dust and debris as the air is pushed through. After multiple uses, the screen may become filled with grime, which not only interferes with how well your hair dryer actually dries your hair, but also shortens the lifespan on the device itself. Clean the screen on your hair dryer at least once a month to ensure its not overheating and that it's working effectively and efficiently.
Turn off your hair dryer and unplug it from the electrical source. Let the hair dryer cool down completely.
Remove the screen guard from the hair dryer. This is typically a plastic piece that snaps over the screen. You may need to twist the guard to remove it, or just snap it off, depending on the model of hair dryer.
Pull as much dust and debris from the screen as possible using your fingers. Scrape the screen gently with a toothpick to further remove the grime.
Dampen a rag with water. Squeeze the rag well so it's just slightly damp and not soaking wet.
Wipe the screen with the damp rag to remove any remaining dust and debris. Go over the screen with a dry rag to remove any moisture. Leave the screen guard off the hair dryer for at least 15 minutes to make sure it's completely dry. Replace the screen guard by twisting or snapping it back into place.
