Lint buildup can fuel dryer fire

Q: I read another columnist recently who warned about keeping dryer vents clean and free of lint, in order to prevent a house fire. Since then, I’ve cleaned the lint trap after every load, and had my son clean behind the dryer (as he’s strong enough to move the appliance). Is there any other area we should clean to make sure all excess dryer lint is gone? — Gladys K., Trenton, N.J.

A: You’ve done a great job in keeping the area around the dryer free of extra lint. Built-up lint can catch fire easily if it contacts a heat source, such as overheated dryer parts or a stray spark.

Another area that needs to be cleaned is the exhaust vent and duct, all the way to the outside of the house, if possible.

Unplug the dryer before cleaning, detach the duct from the back of the dryer, and vacuum the vent and inside the duct using the vacuum hose attachment.

Gardus Inc., which sells a dryer duct-cleaning appliance called the LintEater System, recommends cleaning the vent and duct four times a year.

The company also suggests checking the exterior vent for squirrel or bird nests, and making sure the exterior flap is open when the dryer is on, and closes when the dryer is off.

Other Tips

•Install a smoke alarm near the dryer — test it monthly and replace the battery each year.

•Don’t put rubber-backed bath mats, foam-padded bras or cloth soaked in oil, gas or other flammable chemicals into the dryer.

•Don’t run the dryer when asleep or not at home.
