Vacuum the inside of the lint trap housing, using a long, skinny hose attachment. Follow this initial vacuuming with a second pass using the long flexible brush from the brush kit. Extend the brush all the way into the bottom of the cavity. Using a gentle and slight twisting motion, pull out the brush to extract clumps of lint. Clean the brush bristles with the vacuum. Repeat as needed until there is no more lint that can be removed from the cavity.
