How to Clean the Inside of a Washing Machine Safely and Thoroughly

You need to clean the inside of your washing machine. The drum looks dirty, there’s buildup in the dispenser, and the rubber seal has black spots. A dirty machine transfers soil, bacteria, and odors to your clothes. Cleaning the inside is simple and takes about an hour. Here’s how to clean the inside of a washing machine safely and thoroughly.

Cleaning the inside of a washing machine is the process of removing detergent residue, fabric softener buildup, mineral deposits, bacteria, and mould from the drum, dispenser, rubber seal, and filter. A clean machine cleans clothes better, smells fresh, and lasts longer.

To clean the inside of a washing machine, clean the dispenser with dish soap, wipe the rubber seal with vinegar and water, run a hot cycle with 2 cups of vinegar, run a second hot cycle with half a cup of baking soda, clean the filter, and use affresh monthly. Leave the door open between washes and use 2 tablespoons of detergent per load.

Step-by-Step: Cleaning the Inside of a Washing Machine

Step 1: Clean the Detergent Dispenser

Remove the detergent dispenser (check your manual for how). Soak it in hot water with Dawn Ultra Dish Soap for 30 minutes. Scrub with an old toothbrush to remove buildup. Rinse thoroughly and replace.

Step 2: Wipe the Rubber Seal (Front-Load Only)

Wipe the rubber seal around the door with a cloth soaked in equal parts white vinegar and water. Pull back the folds to clean underneath, where mould and residue hide. Dry with a clean cloth.

Step 3: Clean the Drum with Vinegar

Pour 2 cups of white vinegar into the detergent dispenser. Run the hottest cycle with no clothes. Vinegar kills bacteria, dissolves mineral deposits, and removes odors.

Step 4: Clean the Drum with Baking Soda

Pour half a cup of Arm and Hammer Baking Soda into the drum. Run the hottest cycle with no clothes. Baking soda neutralizes acids and absorbs remaining odors.

Step 5: Use affresh Monthly

For ongoing maintenance, use affresh Washing Machine Cleaner monthly. Place one tablet in the drum and run the hottest cycle.

Step 6: Clean the Filter (Front-Load Only)

Locate the filter access panel (usually at the bottom front). Place a towel underneath to catch water. Open the filter, remove debris, and rinse under running water. Replace.

Step 7: Wipe the Drum

After the cleaning cycles, wipe the drum with a clean, dry cloth to remove any loosened residue.

Step 8: Leave the Door Open

Leave the door and dispenser open to let the machine dry.

For Front-Load Washers

Front-load washers need extra attention to the rubber seal and filter:

• Clean the rubber seal weekly with vinegar and water
• Check the drain filter monthly
• Leave the door and dispenser open between washes
• Use less detergent (2 tablespoons max)

For Top-Load Washers

Top-load washers need attention to:

• The agitator or impeller (wipe with vinegar and water)
• The fabric softener dispenser (remove and clean)
• The drum (run cleaning cycles)
• Under the agitator (check for trapped items)

How to Keep the Inside Clean

Use less detergent. Use 2 tablespoons of Tide Free and Gentle per load. Excess detergent feeds bacteria.

Don’t use fabric softener. Use half a cup of white vinegar in the rinse instead.

Use hot water weekly. Run at least one hot water load per week to kill bacteria.

Use Lysol Laundry Sanitizer. Add to the rinse for heavily soiled loads.

Use OxiClean Max Force Spray for stains. Prevent food and sweat residue from building up.

Use Shout Advanced Grease Busting Foam for grease. Prevent grease buildup.

What Not to Do

Don’t use too much detergent. Excess detergent feeds bacteria and causes odors. Use 2 tablespoons per load.

Don’t use fabric softener. It coats the drum and seal with waxy residue.

Don’t close the door between washes. Trapped moisture causes mould.

Don’t use chlorine bleach in the drum. It can damage rubber seals. Use vinegar or affresh.

Don’t mix vinegar and chlorine bleach. Mixing them creates toxic chlorine gas.

Don’t skip the filter. A clogged filter reduces cleaning and causes odors. Clean monthly.

Don’t use abrasive cleaners on the drum. They can scratch the surface. Use vinegar or affresh.
