How do I deep-clean the lint screen when detergent residue has built up?

Roll lint off the screen with your fingers, then wet both sides of the lint screen with hot water. Scrub the screen with a nylon brush wetted with hot water and liquid detergent to remove residue, rinse with hot water, and thoroughly dry with a clean towel before reinstalling. This deep cleaning should be done every 6 months, or more frequently if the screen becomes clogged.
