How to remove lint buildup from a dryer drum

Posted on

Introduction

Lint buildup inside your dryer drum is more than just an eyesore—it can affect performance, increase drying times, and even contribute to dangerous overheating. While most lint is trapped by the lint screen, some particles escape and cling to the inside of the drum, the seals, and other internal parts. Over time, this buildup can lead to odors, reduced efficiency, and potential fire hazards. This guide will show you how to remove lint buildup from a dryer drum safely and effectively, using simple tools and cleaning methods you can do at home.

Why Removing Lint from the Dryer Drum Matters

While cleaning the lint trap after every load is essential, it’s not enough to keep your dryer completely lint-free. Small amounts of lint bypass the filter and cling to the drum and surrounding areas.

Benefits of removing lint buildup include:

  • Improved Efficiency: A clean drum allows clothes to tumble freely, improving airflow.
  • Reduced Fire Risk: Lint is highly flammable, and buildup increases the chance of overheating.
  • Faster Drying Times: Less obstruction means hot air circulates better.
  • Fresher Laundry: Removes musty odors caused by trapped lint and debris.
  • Longer Appliance Life: Reduces strain on the dryer’s motor and heating system.

By making drum cleaning part of your regular dryer maintenance, you’ll keep your appliance safe and running smoothly.

Step-by-Step Guide to Removing Lint Buildup from a Dryer Drum

1. Gather Your Cleaning Supplies

You’ll need:

  • Microfiber cloth or lint-free towel
  • Warm water
  • Mild dish soap
  • White vinegar (for stubborn residue)
  • Vacuum cleaner with hose attachment
  • Soft brush attachment (optional)

2. Unplug the Dryer for Safety

Before starting any cleaning, unplug your dryer to prevent accidental operation. If you have a gas dryer, turn off the gas supply as well.

3. Remove Any Visible Lint by Hand

Check the drum for large pieces of lint, threads, or debris and remove them manually. Be sure to check around the edges and seals, where lint tends to collect.

4. Vacuum the Drum Interior

Using a vacuum with a hose and soft brush attachment:

  1. Gently run the nozzle along the inside of the drum to pick up loose lint particles.
  2. Pay special attention to the back panel and edges near the door seal.
  3. If your vacuum hose can reach, gently clean the area just inside the air vents at the back of the drum.

5. Wipe the Drum with Soapy Water

Mix a small amount of mild dish soap with warm water.

  1. Dampen a microfiber cloth with the soapy water (avoid dripping wet cloths).
  2. Wipe the entire drum interior in circular motions.
  3. Rinse the cloth often to avoid spreading lint around.

6. Tackle Stubborn Lint with Vinegar

If lint is stuck due to static or residue from dryer sheets:

  1. Mix equal parts white vinegar and water in a small bowl.
  2. Dampen a clean cloth with the solution.
  3. Wipe affected areas, then follow with a dry cloth to remove moisture.

Tip: Vinegar also helps neutralize musty odors inside the drum.

7. Clean the Door Seal and Lint Trap Housing

Lint can collect around the door seal and inside the lint trap slot.

  1. Wipe the rubber or felt seal around the door with a soapy cloth.
  2. Use a vacuum hose to clean inside the lint trap opening.
  3. If the trap housing is especially dirty, use a narrow crevice tool for better reach.

8. Check and Clean the Rear Air Vent (If Accessible)

If your dryer allows safe access to the rear vent from inside the drum:

  1. Use a vacuum to remove lint from the vent holes.
  2. Be careful not to damage the vent openings or internal components.

9. Dry the Drum Completely

After cleaning, use a dry microfiber cloth to remove any moisture from the drum. This prevents rust and keeps lint from sticking immediately after cleaning.

10. Plug the Dryer Back In and Test

Once everything is clean and dry, plug the dryer back in (and turn the gas supply back on if applicable). Run the dryer empty for 5–10 minutes on the air-fluff setting to ensure any remaining lint particles are blown out.

Common Mistakes to Avoid

  1. Using Abrasive Cleaners
    • Mistake: Harsh scrubbing pads can scratch the drum’s interior.
    • Solution: Stick to microfiber cloths and mild cleaning solutions.
  2. Skipping the Vacuum Step
    • Mistake: Wiping without vacuuming first can spread lint around.
    • Solution: Always vacuum loose lint before wet cleaning.
  3. Forgetting the Door Seal
    • Mistake: Lint hiding in the seal can cause odors and block airflow.
    • Solution: Clean seals every time you deep clean the drum.
  4. Leaving the Drum Wet
    • Mistake: Moisture left inside can cause rust and odors.
    • Solution: Always dry the drum thoroughly after cleaning.
  5. Not Cleaning Regularly
    • Mistake: Letting lint buildup over months makes cleaning harder.
    • Solution: Clean the drum every 1–2 months depending on dryer use.

Extra Laundry Tips & Hacks

  • Shake Clothes Before Drying: Reduces lint shedding inside the dryer.
  • Use Wool Dryer Balls: They help prevent static, which reduces lint sticking to the drum.
  • Empty Lint Trap Every Load: Prevents excess lint from entering the drum.
  • Monthly Quick Freshen: Wipe the drum with a vinegar-water solution to keep it clean between deep cleans.
