The Ultimate Guide to Cleaning Washing Machine Rubber Seal Properly

If you’ve noticed a musty smell in your laundry or black mould forming in your washing machine, the culprit is likely your rubber door seal. Cleaning washing machine rubber seal areas regularly is essential to maintain hygiene, prevent damage, and keep your clothes fresh.

In this guide, we’ll walk you through the most effective, safe, and eco-friendly ways to clean the rubber seal — a commonly neglected part of the machine. We’ll also explain why it’s so important and how to maintain it long-term for the health of your machine and your family.

Why You Need to Be Cleaning Washing Machine Rubber Seal

The rubber seal (or gasket) around the washing machine door is designed to prevent leaks during a wash cycle. However, its flexible shape also traps:

  • Moisture
  • Soap residue
  • Lint
  • Hair
  • Bacteria and mould spores

Left uncleaned, this results in mould on rubber seal surfaces, foul odours, and even damage to the washing machine’s internal parts.

Routine cleaning of the rubber seal helps:

  • Extend the life of your machine
  • Prevent costly repairs
  • Protect clothes from mildew smell or marks
  • Improve washing performance

How Often Should You Be Cleaning Washing Machine Rubber Seal?

Cleaning the washing machine rubber seal at least once a month is recommended. However, homes with high washing frequency (like families or pet owners) should aim for fortnightly cleaning.

Step-by-Step: Cleaning Washing Machine Rubber Seal Properly

1. Switch Off and Open the Door

Start by turning off the machine for safety. Pull back the rubber seal gently to expose the inner folds where most grime hides.

2. Remove Loose Debris

Use a dry cloth or kitchen towel to wipe away:

  • Hair
  • Fluff
  • Loose dirt
  • Visible mildew

This prevents these bits from becoming harder to remove when wet.

3. Use a Homemade Cleaning Solution

A mix of white vinegar and bicarbonate of soda works wonders. It’s also eco-friendly and safe on rubber.

DIY Natural Cleaner:

  • 1 part white vinegar
  • 1 part warm water
  • 1 teaspoon bicarbonate of soda

Pour into a spray bottle and shake.

Alternatively, use a mild rubber-safe commercial cleaner.

4. Spray and Scrub

Spray the solution generously on the rubber gasket and into the folds. Leave for 5 minutes. Use an old toothbrush or soft cloth to scrub gently but thoroughly.

Focus especially on blackened areas or where mould on rubber seal is visible.

5. Wipe Clean and Dry

Use a damp cloth to wipe away the cleaner and loosened grime. Follow up with a dry towel to eliminate remaining moisture — essential to prevent mildew re-growth.

Preventing Future Build-Up

To reduce how often you’ll need deep cleans, follow these simple maintenance tips:

  • Leave the door ajar after each wash to allow drying
  • Wipe down the seal with a dry cloth after every use
  • Run a monthly hot wash cycle with a cup of white vinegar
  • Avoid overloading the machine
  • Remove wet laundry promptly
  • Use a high-quality, low-suds detergent
