Start by unplugging your hair dryer to ensure safety. Wipe down the exterior surfaces with a damp microfiber cloth to remove any buildup. For a deeper clean, carefully remove the back of the dryer to access the vent. Use a damp microfiber cloth or a clean, unused toothbrush to gently scrub away any dust or debris. To tackle hard-to-reach areas inside the filter, use the nozzle of a vacuum cleaner to effectively suction out dust and lint.
