Always unplug a hair dryer before performing any cleaning, even if it features a shock protector on the plug. Also, don’t try to disassemble a hair dryer to clean the inside, and don’t ever immerse a dryer in water, even an unplugged one.

Clean the plastic case with a damp sponge and maybe a soapy solution, and wipe dry with a soft cloth. Clear and loosen dust and hair from grills — dryers have both an intake and an exhaust, which is the hot end — using an old toothbrush. Loose debris remaining on the screens can be vacuumed out using a crevice tool or the upholstery brush.

Dryer attachments can be detached and cleaned like hairbrushes, in a sink full of warm, soapy water.

For safety’s sake, ensure the case and all components are completely dry before plugging in and using a hair dryer.
