Dampen a soft, lint-free cloth with a mild detergent mixture to clean the exterior of the heater. Avoid harsh and abrasive cleaners, which can damage the heater's finish.
Remove dust from inside the interior reflector by placing the unit on its back and inserting a soft, lint-free cloth through the grille. Use the handle of a long wooden spoon or something similar to move the cloth around inside the unit to remove dust. Remove dust from the heater regularly because dust accumulation on the interior parabolic reflector can cause the unit to overheat.
