How do you clean the inside of a dryer?

1. Remove lint from the lint trap

A lint-free trap provides better airflow for optimal performance, so a thorough clean can go a long way. To clean the lint trap:

  • Remove the lint screen and set aside.

  • Vacuum the interior and exterior of the lint trap with a vacuum crevice tool or brush.

  • Vacuum the moisture sensor strips on the outside of the lint trap.

  • Replace the lint screen.

2. Turn off and unplug dryer

Shutting off the power to the dryer while cleaning prevents accidental operation while parts are removed or disconnected, so unplug your dryer from the wall socket before you get started. If you have a gas dryer, close the shut-off valve in the gas supply line, then disconnect and cap the supply line pipe before cleaning.

3. Wipe residue off dryer drum

Dryer sheets and fabric softeners can contribute to a filmy residue on your dryer’s drum over time. Start cleaning by vacuuming out any debris. If your dryer is electric, rub the drum with a soft cloth dipped in warm water and dish soap. For a gas dryer, wipe down the inside with a liquid, nonflammable household cleaner. Then, for gas or electric, wipe out the drum with a wet sponge or towel and tumble a load of clean clothes or towels to dry the drum.

4. Pull out the dryer to access vent duct

Create about one foot of room between the back of the dryer and wall to make space for clearing out debris. Enlist some help when moving the dryer to keep yourself and the dryer safe.

5. Remove clamps and detach vent

With the dryer away from the wall, unscrew vent clamps or remove tape attaching the vent to the back of the dryer. You may need a screwdriver to remove the clamps.

6. Clean debris from the vent

Your hands, a vent cleaning tool like this dryer cleaning brush from Whirlpool brand and a vacuum with a hose can work in tandem to get the inside of your dryer’s vent clean. Start by removing any large pieces of lint with your hands, then use a dryer cleaning brush to remove remaining lint from the vent. Next, use a vacuum hose attachment to collect lint or dust trapped in crevices.

7. Inspect and clean the exterior vent

You can find your dryer’s exterior vent outside of your home—typically on your home’s siding or roof. Clean the exterior by opening the vent cover and removing large pieces of lint with your hand. Then run a dryer cleaning brush along the inside of the ductwork and remove remaining lint or debris with a vacuum hose.

8. Reattach the vent and turn on the dryer

Head back inside and re-clamp or re-tape the venting to the back of the dryer. Plug your dryer back in and, if using a gas dryer, turn the gas valve back on.

How do you clean the outside of a dryer?

Residue from detergent drips, fabric softeners and lint can get caked onto the top and sides of the dryer. Keep surfaces clean by spraying the outside of the dryer with a solution of equal parts water and vinegar, then using a microfiber cloth to wipe away stuck-on gunk from the dryer’s surface, knobs and buttons.

How often should a dryer be cleaned?

Specific parts of your dryer require their own unique maintenance schedule. Since your dryer’s exterior, drum and lint trap are easier to see, you can keep an eye on residue and lint build-up to know when it’s time for a thorough clean. You can also run your hand along the sides of the dryer and the inside of the drum to feel for residue build-up. Some dryer parts—like the vents and lint trap—have a more predictable cleaning schedule that’s necessary to help your dryer deliver results.

Once every two years: clean dryer vent and ducts

Cleaning your dryer’s vent and ductwork helps prevent lint build-up from obstructing air flow and impairing your dryer’s performance. Unless otherwise instructed in your owner’s manual, clean your dryer’s venting at least once every two years. You may want to clean it more often if you notice your dryer starting to struggle with drying loads.

After every load: clean dryer lint screen

A screen blocked by lint can increase drying time. It is important to clean your lint screen after every use. Locate your dryer's lint screen, which is most likely near the dryer door. Remove the screen by pulling up, then gently remove the lint from the screen by hand and put the lint trap back. Wet lint is harder to remove, so don't scrub or use water.

Every 6 months: deep clean lint screen

The laundry detergent and fabric softener that builds up on your lint screen can increase drying time. If you notice lint collecting on areas of the screen or plugging the mesh, the screen may be more difficult to clean by hand.

To deep clean the lint screen, roll lint off, then wet both sides with hot water. Scrub with a nylon brush, hot water and liquid detergent to remove buildup. Rinse the screen with hot water and dry thoroughly.
