Keep your clothes dryer operating at its best by making sure the dryer and exhaust vents are free of excessive lint and dust. The more blocked the vents are, the harder and longer it takes to dry clothes.
Always clean out the lint before and after each load of laundry. Periodically clean out dust and lint around and behind the dryer. The Association of Home Appliance Manufacturers also recommends having a professional cleaning of the dryer and ductwork.
