Clean dryer vent duct

Why it matters

The dryer vent duct is the #1 cause of dryer fires. Lint bypasses the trap and accumulates in the duct over months. When enough builds up near the hot exhaust — it ignites. An annual cleaning is the single most important laundry maintenance task.

Stop forgetting to do this.
