Some people think that cleaning the lint trap is enough to keep the dryer lint-free. However, lint somehow finds its way to the dryer vent where it gets stuck. Left uncleaned, it could build up and start clogging the vent. When the airflow is blocked, the dryer won’t be able to ventilate properly and this could cause it to overheat. A fire can ignite and, because lint is dry and made of fabric fiber, it is a highly flammable material. Dryer vent cleaning needs to be done regularly to avoid clogging and to prevent house fires, dryer damage, carbon monoxide poisoning, and moisture damage.
