How to Clean Washing Machine Door Seal: 5 Proven Methods to Remove Mold and Odors

Excess moisture, detergent residues, and poor ventilation are the main reasons washing machine door seals become dirty and smelly. If left unattended, mold and bacteria will build up and affect your laundry and health. Luckily, keeping this part clean is easier than most people think. In this guide, we’ll show you 5 practical and safe ways to clean your washing machine door seal, plus easy maintenance habits to keep it spotless.

1. Scrub with baking soda and a touch of white vinegar

This natural combo is well-known for home cleaning—but overusing vinegar can damage rubber in the long run. Use this method no more than once a month.

a. How to do it safely

• Sprinkle baking soda directly on the rubber seal.
• Spray a small amount of white vinegar on top.
• Let it sit for 10–15 minutes.
• Gently scrub with a soft brush (like an old toothbrush).
• Wipe clean with warm water and dry thoroughly.

FAQ:
Can I use vinegar weekly?
→ No. It’s too acidic for frequent use on rubber seals.

2. Fight black mold with hydrogen peroxide

Hydrogen peroxide (3%) is a safe, bleach-free way to kill mold without damaging the seal or leaving toxic fumes.

a. Step-by-step method

• Soak a clean cloth with hydrogen peroxide.
• Apply it directly to the moldy areas.
• Leave it for 15 minutes.
• Wipe and scrub if needed.

Real-life tip: Julie, a mom of three, uses this every month. No more mildew smell, and her seal still looks like new.

3. Deep-clean using washing soda (soda crystals)

If your washer runs daily or handles heavy loads, washing soda is your friend. It’s a strong degreaser and disinfectant that removes buildup quickly.

a. Directions

• Dissolve 1 tablespoon of washing soda in 1 liter of hot water.
• Soak a sponge and wipe the seal thoroughly.
• Rinse with clean water.
• Dry with a soft cloth.

Tip: Wear gloves—washing soda can irritate the skin.

4. Weekly care with dish soap and warm water

Sometimes, the best solution is the simplest. A gentle wipe once a week can prevent grime from forming in the first place.

a. Easy weekly routine

• Mix warm water with mild dish soap.
• Use a microfiber cloth to clean the folds of the seal.
• Rinse and dry well.

Bonus tip: This works great for households with pets or frequent laundry loads.

5. Long-term maintenance habits that prevent mold

Prevention matters more than any cleaner. Mold loves moisture—starve it by keeping your washer dry and ventilated.

a. Must-do habits

• Always leave the washer door open after use.
• Wipe the seal dry with a cloth after each cycle.
• Clean the filter and detergent drawer once a month.

FAQ:
Why does my washer still smell even after cleaning the seal?
→ You probably need to clean the filter or detergent drawer.
Do I need to replace the seal?
→ Only if it’s cracked, torn, or permanently stained.
