Cleaning a dryer vent is easy if you have a right tool. I use an inexpensive dryer duct cleaning tool called the Gardus Lint Eater. It is a series of flexible piping that link together and has a big brush on the end. It snakes its way through your dryer venting system and will get rid of all of those dangerous lint bunnies lurking in the dryer vent.
Cleaning your dryer vent is an important maintenance job. If ducts are blocked or restricted, the dryer has to run all that much longer to dry your clothes, running up electric and gas bills in the process. More importantly, blocked dryer ducts are a real danger. Over 15,000 dryer fires occur each year, many as the result of dirty dryer ducts.
Lastly, it is also important to replace plastic or vinyl dryer ducts with metal duct material, which is sturdy, making it easier to clean your dryer vents.
