Routine Dryer Cleaning Everyone Should Do

Woman Taking the lent of Dryer

You might think your dryer doesn’t need cleaning because it only touches freshly washed clothes … and you’d be wrong.

Dryers collect lots of lint, which can clog vents, restrict airflow, affect how well the machine dries, and even burn out the heating element quickly. Oh, and excess lint can catch fire, as my colleague, Tom, shares in “Real-Life Warning: A Family’s Close Call with a Dryer Fire,” below. 

Fortunately, cleaning a dryer is simple: wipe down the drum, clean out the lint trap after every use and vacuum lint fluffies behind the machine. We’ll also tell you how to get rid of ink stains, gum, and other stubborn substances that dryers sometimes attract.

Project difficulty: Easy to moderate—most tasks can be done by any homeowner with basic tools, though vent cleaning may require professional help
Time required: 30 to 60 minutes for a thorough cleaning
Overall cost: $0 to $20—most of the supplies are common household items.

Always unplug dryers and shut off the gas supply (for gas dryers) before cleaning the drum to prevent electric shocks or other mishaps. 

For gas dryers, use only non-flammable cleaning solutions like mild soap and water as residue could create a fire hazard when the dryer is turned on.

Clean Inside the Dryer

It is important to clean your dryer’s interior regularly to keep it running efficiently and safely. Here are the steps you need to follow to clean each component.

Lint Trap

Lint should be removed after every use. Give the screen a good scrub at least every 6 months. Keeping the lint screen clean will keep your dryer running smoothly and safely. Here’s how to clean your dryer’s lint trap:

  1. Remove the lint trap.
  2. Gently peel away or brush off accumulated lint
  3. Rinse both sides with hot water
  4. Apply a few drops of liquid dish soap and scrub with a soft nylon brush or old toothbrush
  5. Rinse thoroughly with hot water
  6. Let dry completely before reinstalling
  7. Use a vacuum brush or crevice tool to vacuum the lint trap’s exterior and interior

Quick tip: For heavy buildup, often caused by dryer sheets, soak the screen in hot soapy water for 10 minutes. 

Dryer Drum

Clean the drum once a month, or any time you spot visible residue, fabric softener buildup or discoloration. This routine care prevents stains from transferring to your clothes and helps your dryer last longer.

  1. Use a commercial dryer cleaner spray and damp microfiber cloth with a couple of drops of dishwashing soap. 
  2. Wipe the drum with the cloth to remove any buildup or grime.
  3. Wipe the drum with a fresh, dry cloth, then run a load of clean towels to ensure it’s completely dry.

If you have kids, you know too well that they are prone to leave things in their pockets. And when those things are pens and gum, you’re likely to find ugly, baked on smears in your drum from time to time. 

Moisture Sensor

Many modern dryers have moisture sensor bars (typically near the front of the drum) that should be cleaned every 6 months. These metal bars determine when clothes are dry, and regular cleaning ensures the drying times are accurate.

  1. Locate the metal bars inside the dryer drum.
  2. Gently clean them with a damp cloth with just a drop or two of dish soap.
  3. Wipe with a clean cloth until dry.
  4. Test the bars with your fingers to ensure they are completely dry. Wipe again if still damp.

Clean the Vent

Clean out your dryer vent at least once a year. If you have heavy dryer use or pets that shed, then every 6 months is better. Regular vent cleaning is crucial to prevent fires from lint buildup and keep your dryer working like it’s supposed to.

  1. Disconnect the power cord for the dryer.
  2. Carefully pull the dryer away from the wall. Protect your floors by putting furniture movers or cardboard under the feet.
  3. Remove the clamp to disconnect the vent duct.
  4. Use a dryer vent brush to remove lint buildup from the hose.
  5. Vacuum debris from both ends of the hose, and behind the dryer.
  6. Check for damage and replace the duct hose if necessary.
  7. Reconnect the vent duct and secure it with the clamp.

Clean the Outside

Take 5 to 10 minutes a month to clean the outside of your dryer. This simple maintenance routine prevents rust, protects the components of the control panel from dirt and debris, plus it keeps your laundry clean.

  1. Use one of the following cleaning solutions:
    • All-purpose, non-abrasive cleaner
    • Equal parts white vinegar and water
    • Warm water and a few drops of dish soap (okay for stainless steel)
    • Specialized stainless steel cleaner

Quick tip: For stainless steel dryers, always use a soft cloth and wipe in the direction of the grain, then buff dry. This will prevent scratches and preserve the finish.

  1. After cleaning the dryer’s outer shell, use a damp cloth to wipe around the control panel and knobs. Dry thoroughly with a clean cloth to avoid moisture seeping into them.
  2. Pull the dryer out a bit, if possible, and tackle the back panel or use a vacuum attachment to get the dust and lint that can collect in this hidden area.

Real-Life Warning: A Family’s Close Call with a Dryer Fire

One of my colleagues, Tom McNiff, recalled an instance some years ago when he took his family on vacation to Gatlinburg, Tenn. They checked in at the rented home, an amazing rustic cabin on a mountainside, and threw in a load of laundry, then transferred the freshly washed load to the dryer a bit later.

As they settled in by the fireplace for the evening, his wife spotted smoke billowing from the laundry room: the dryer was on fire. As his wife ushered the kids safely outside, Tom snatched the fire extinguisher off the wall and squelched the flames long enough for the fire department to arrive and finish the job.

The firefighters yanked the charred dryer away from the wall to inspect it, and, just as they suspected, the lint trap was stuffed full of scorched fabric.
