Dryer residue is a common problem that can occur when clothes are dried in a dryer. LINT, which is a four-letter word, is a type of dryer residue that consists of small fibers from fabrics that accumulate on the LINT screen of the dryer. FLUFF, a five-letter word, is another type of dryer residue that is made up of small pieces of fabric and other materials that accumulate in the dryer. Both LINT and FLUFF can cause problems with the dryer's performance and should be removed regularly.
