The lint trap in a dryer is designed to catch lint, debris and all other clothing fibers during each drying cycle. However, after multiple uses, oils and residues are building up and it can clog up the lint trap screen. And removing it manually is no longer viable because it won’t be much effective. On top of that, if kept prolonged and neglected, all that lint build up can push through around the edges of the lint trap and into the dryer cavity. Which could end up being a serious fire hazard. So to prevent this from happening, the lint screen should be cleaned thoroughly and regularly to maintain its efficiency and safety.
