How to sanitize laundry appliances safely

Posted on

Introduction

Over time, washers and dryers can harbor bacteria, mold, and odors—especially in damp environments. Even if your clothes come out looking clean, your laundry appliances might be hiding unseen grime. Learning how to sanitize laundry appliances safely ensures your clothes stay truly fresh, prevents unpleasant smells, and keeps your laundry room hygienic.

This guide will walk you through safe, effective methods for cleaning your washer and dryer without damaging them, so you can maintain both performance and safety.

Why Sanitizing Laundry Appliances Matters

Your washer and dryer work hard every week. Over time, they collect:

  • Detergent residue that traps dirt and bacteria.
  • Lint and dust buildup that can reduce efficiency.
  • Moisture that encourages mold and mildew.

By sanitizing regularly, you:

  • Prevent musty odors from transferring to clothes.
  • Reduce the risk of bacteria and allergen growth.
  • Keep your appliances working at peak performance.
  • Extend the life of your washer and dryer.

Step-by-Step Guide to Sanitizing Laundry Appliances Safely

1. Unplug and Prepare Your Appliances

  • Always unplug your washer and dryer before cleaning to avoid electrical hazards.
  • For gas dryers, turn off the gas valve.
  • Pull appliances slightly away from the wall for better access to the sides and back.

2. Sanitize the Washing Machine

A. Front-Load Washers

  1. Clean the Rubber Gasket
    • Pull back the door gasket gently.
    • Wipe with a cloth dipped in a solution of equal parts water and white vinegar.
    • Pay attention to hidden spots where mold collects.
  2. Run a Sanitize Cycle
    • If your washer has a sanitize setting, use it with no clothes.
    • Add 2 cups of white vinegar directly to the drum.
    • Afterward, run a second empty cycle with ½ cup of baking soda to neutralize odors.
  3. Clean the Detergent Drawer
    • Remove and soak in warm, soapy water.
    • Scrub away residue with a soft brush, rinse, and dry.
  4. Flush the Drain Pump Filter
    • Check your manual for the location.
    • Remove debris and rinse the filter thoroughly.

B. Top-Load Washers

  1. Fill the drum with hot water.
  2. Add 4 cups of white vinegar and run a full wash cycle without clothes.
  3. Fill again with hot water, add 1 cup of baking soda, and run another cycle.
  4. Wipe the inside of the lid and agitator with a microfiber cloth dipped in vinegar water.

3. Sanitize the Dryer

A. Clean the Lint Trap and Housing

  1. Remove the lint screen and wash it with warm, soapy water.
  2. Use a vacuum crevice tool to clean lint inside the housing.

B. Wipe Down the Drum

  1. Mix a mild disinfectant solution—1 part vinegar to 3 parts water.
  2. Wipe the drum, door, and seals with a soft cloth.
  3. Leave the door open to dry completely.

C. Clean the Moisture Sensor Strips

  1. Locate the metal strips inside the drum (often near the lint trap).
  2. Wipe them with a cloth and rubbing alcohol to remove fabric softener residue.

D. Clear the Vent Duct

  1. Disconnect the vent hose from the back of the dryer.
  2. Use a vent brush or vacuum to remove lint buildup.
  3. Reconnect securely.

4. Clean the Exterior Surfaces

  • Use a damp cloth with mild dish soap to wipe down the tops, sides, and control panels of both appliances.
  • Avoid abrasive cleaners that can scratch surfaces.

5. Refresh the Laundry Area

  • Vacuum the floor behind and beneath appliances.
  • Wipe baseboards and surrounding shelves.
  • Keep the space dry to prevent mold growth.

Common Mistakes to Avoid

  1. Using Harsh Chemicals
    • Avoid bleach directly on rubber gaskets—it can weaken them. Vinegar and baking soda are safer options.
  2. Skipping the Lint Trap
    • Lint buildup isn’t just dirty—it’s a fire hazard. Always clean before or after every load.
  3. Forgetting the Door Seal
    • Mold often hides in the folds of front-load gaskets. Skipping this step means odors will return quickly.
  4. Leaving Moisture Inside
    • Always leave washer and dryer doors slightly open after use to allow air circulation.
  5. Neglecting the Vent
    • A clogged dryer vent reduces efficiency and increases fire risk.

Extra Laundry Tips & Hacks

  • Monthly Maintenance – Run a vinegar and baking soda cycle once a month to keep washers fresh.
  • Natural Freshness Boost – Add a few drops of tea tree oil to your cleaning solution for natural antibacterial benefits.
  • Gasket Drying Trick – Keep a small microfiber cloth tucked in the laundry room to wipe the washer gasket after every load.
  • Detergent Control – Use the recommended detergent amount; excess causes residue buildup.
