Cleaning the clothes dryer vent is a large pain in the butt. Lint builds up until the dryer cease to dry clothes because it can not exhaust the moist air. I used to take the apart and ram my arm in to clear out the lint. This was messy and time consuming. Today, I figured out a better way. I went to the garage and retrieved my leaf blower. I then pulled the bottom of the dryer vent off of the dryer and inserted the end of the leaf blower. I turned on the leaf blower for about three seconds. Then I put the bottom of the vent back on the dryer and was finished. It took about three minutes, including getting and returning the leaf blower. When I looked outside, the grass near the vent outlet was covered with lint. The dryer began drying properly again. Cost ZERO.
