Slide a pillowcase over each blade and wipe—dust collects inside the fabric instead of falling.

Always vent outside (never into an attic or wall). Use rigid or flexible ducting with minimal bends, and insulate ducts in cold climates to prevent condensation.

Turn off power, remove the cover, vacuum dust/debris, wipe blades with a damp cloth, and clean the grill with soapy water. Repeat every 3-6 months.
