According to the U.S. Fire Administration, failure to clean the dryer is the leading cause of dryer fires, which cause around $35 million in property loss each year. You may think you’re doing a good job of cleaning your lint trap every time you dry clothes, but if you’re not doing a periodic deep-clean, your dryer is still in jeopardy. Here’s everything you need to know to thoroughly clean your dryer lint trap.

How to Clean a Lint Filter In a Dryer

Cleaning your dryer's lint filter and housing is as simple as disassembling, removing debris, and reassembling. A cleaning solution and a few tools, such as a brush and vacuum cleaner, are all you'll need.

  1. Take Out the Screen

    Start by removing the screen on your dryer vent. The screen might be screwed in for older models, so you’ll need to use your screwdriver to remove the screws before you pull out the screen.

  2. Remove Accumulated Lint

    As you would do between laundry loads, use your hands to remove any built-up lint on the screen. Depending on the shape of the filter, this step may mean simply peeling back and discarding the built-up lint or using a finger or two to pry the lint away from its surface. In either case, remove as much of the lint build-up as possible to make the next steps easier.

  3. Soak the Screen

    Next, fill either your sink or a bucket with warm water, a few drops of dish soap, and 1/2 cup of white vinegar. Without bending or warping the screen, fully submerge it in the water and let it soak for 30 minutes.

  4. Scrub the Screen

    After 30 minutes of soaking, remove the screen from the water and scrub it gently with your soft bristle brush. You can use a toothbrush to get into all the nooks and hard-to-reach corners that your larger brush might not reach. Continue scrubbing until you’ve removed all the stuck-on lint and dirt.

    If it’s particularly dirty, you can deep-clean the lint screen to prevent common dryer problems.

    Using a store-bought cleaning solution, spray the mixture on your screen over the sink, and scrub with a soft brush. Rinse the screen thoroughly, and repeat the process until it’s clean.

    A baking soda and vinegar mixture can also deep-clean your lint screen. Put your screen in the sink and sprinkle it with baking soda, then spray vinegar all over the screen using a spray bottle. This will cause a chemical reaction where the vinegar and baking soda fizzes and bubbles up. Leave the mixture on for a few minutes, then scrub with a soft brush while rinsing the screen.

    Once you’ve gotten all the residue off of your dryer screen, rinse well with warm water. This is an essential step because you can tell how the water runs through the screen if you’ve got all the residue off. If the water flows through the screen, you’re good to go. If water collects on the screen or forms bubbles, you need to do a deeper cleaning or soak the screen again and repeat the scrubbing process.

  5. Dry the Screen

    When you’re sure the screen is spotless, allow it to air-dry thoroughly before putting it back in the dryer. If you put a damp screen back in the dryer, lint will form clumps that’ll clog your vents and cause a fire hazard, or your screen might rust.

  6. Vacuum Out the Lint Trap Slot

    While the screen is soaking, use your vacuum with the extended hose attachment to vacuum around the lint trap. Then, clean inside the lint trap using either your dryer vent cleaning kit or a paper towel cardboard tube. If you’re using the tube, tape it to the extended hose attachment with packing or duct tape to create a tight seal. Check frequently to make sure lint isn’t clogging the end. Keep vacuuming until you’ve gotten all the lint cleaned out.

  7. Vacuum Under the Dryer

    Using the appropriate attachment, vacuum up any fuzz or lint from beneath and around the dryer since some dust probably fell out of the lint trap as you were cleaning it.

Tips for Maintaining Your Dryer

Regular dryer maintenance not only keeps your clothes smelling fresh, but can also protect your house against deadly fires. While you’re cleaning your lint trap, schedule these other maintenance tasks:

  • Clear your dryer lint trap of any lint after every cycle.

  • Hire a dryer vent cleaning service once a year to thoroughly clean your vent system. This task is best left to a local dryer vent pro.

  • Clean your dryer annually to avoid any lint or debris buildup.

  • Don’t overload your dryer to avoid extra strain on the system.

DIY Dryer Cleaning vs. Hiring a Dryer Vent Pro

Occasionally cleaning your dryer lint trap as a DIY project is straightforward. However, cleaning the rest of the machine's venting system is another story. Your dryer's lint filter and assembly connect to the rest of the vent, which exhausts hot air and humidity to the outdoors. The full vent system requires annual cleanings at a minimum.

While it's possible to perform this task yourself, a local dryer vent cleaning specialist has the tools and experience to ensure professional results. A dryer vent pro will also ensure that the venting system is put back together correctly to ensure safety and efficiency. The average cost of dryer vent system cleaning is around $145

Frequently Asked Questions

Lint is very flammable. Pair that with the hot heat your dryer produces as it runs, it creates a recipe for sparks and flames. Lint build up is the leading cause of dryer fires, so running routine maintenance on your dryer lint trap is critical to keep your home safe.

You should clear your dryer lint trap after every cycle, but a deeper clean is needing only one a year. Failure to clear your lint trap regularly results in lint building up over time, making it harder to clean and more expensive.

The main factor to a full lint trap is what you are drying. Clothing or textiles made of heavy natural materials, like wool sweaters or cotton towels, generally create more lint than synthetic fibers. If you wash the same type of clothes all the time and suddenly start to notice more lint, that may be a sign that your dryer vent is getting clogged and you need to call in a pro for a professional cleaning.
