Have you noticed that your dryer just isn’t getting the job done like it used to? Maybe your clothes are coming out still a bit damp, or you’re finding that you need to run an additional cycle every time you do laundry. These are good indications that it’s time to clean your dryer vent. Not only will this increase the efficiency of your machine, but if it isn’t done frequently enough you may encounter a fire hazard.

How often do I need to clean my dryer vent?

You should aim to clean your dryer vent at least once per year. If you have a large family or use your machine very frequently, you may want to increase this to twice per year or even quarterly. It can be helpful to add tasks like this to a list of other annual or semi-annual cleaning and home upkeep jobs. For example, maybe you choose to clean your dryer vents, check your smoke detector batteries and clean out your gutters during the first week of spring and the first week of fall each year. Putting these tasks into a routine means you won’t have to wonder if they’ve been done recently enough or try to remember to work them into your schedule.

Why do I need to clean my dryer vent?

Proper cleaning and maintenance of your appliances means they’ll last longer and you’ll get more life out of them before a replacement is needed. It will also ensure that your clothes are drying quickly, eliminating the need to run multiple cycles. By keeping your dryer in top working condition, you’re saving time and energy. But most importantly, if your dryer vents get clogged, it can trap heat inside the dryer and cause the items inside to catch fire. According to the U.S. Fire Administration, there are an average of 2,900 home clothes dryer fires per year. The leading cause of these fires is failure to properly clean them.

How do I clean my dryer vent?

Follow the steps below to ensure proper cleaning and maintenance of your dryer.

1. Start with the lint trap.

This is the easy part. You should empty the lint trap every time you use the dryer. But, if you use dryer sheets, film can build up on the lint trap over time. You’ll want to make sure you aren’t getting a film over the screen. Put a small amount of water on the lint trap. If the water pools on the surface rather than running through, you need to remove buildup by scrubbing the screen with some soapy water and a gentle brush.

2. Unplug the dryer.

Don’t forget this step. Before you start detaching or cleaning anything from the back of the dryer, unplug your dryer so it is no longer drawing electricity. If you have a gas dryer, turn the supply valve off.

3. Detach the vent hose from the wall.

You’ll want to pull the dryer away from the wall, about 2 feet. Then carefully remove the vent hose from the back of the dryer. You may need a screwdriver to do this. 

4. Remove and clean the hose.

Use your hands to scoop out any lint at the front of the hose. You may want to wear rubber gloves for this. Then, using the hose extension on your vacuum cleaner or a shop vac, gently suction the lint out of the hose. If there is too much buildup, you may need to snake the hose with a wire hanger. Again, do this gently and take care not to puncture the hose with the hanger.

5. Reattach the hose and clean the exterior vent.

Securely re-attach the hose to the back of the dryer, re-inserting any screws if you removed them. Slide your dryer back into place and head outside to clean the exterior vent. Remove the exterior vent and use your hands to clean out any built-up lint. 

Once your vents are clear, plug your dryer back in and run the empty machine on the air-dry setting for 20-30 minutes. During this time, be sure to check outside and make sure that the air is running through the vent.

Be sure to perform this maintenance at least once a year, more often if you have a large family or do large amounts of laundry. If you noticed buildup from dryer sheets, limit the number of sheets you use to one per load, or consider using a more environmentally friendly option like wool dryer balls.
