How to Clean Washing Machine Rubber Seal: Step-by-Step for UK Homes

If you’ve ever opened your washing machine door and been met with an unpleasant odour — or spotted black marks around the door — the rubber seal is the likely culprit. Learning how to clean washing machine rubber seal is essential for any UK household wanting fresh laundry and a mould-free appliance.

In this guide, we’ll walk you through how to clean washing machine rubber seal safely and effectively. With easy steps and tips tailored to UK homes, you’ll keep your machine running cleaner for longer.

Why You Need to Know How to Clean the Washing Machine Rubber Seal

The rubber door gasket — often made from silicone rubber — creates a watertight seal when the machine is in use. However, its design also traps:

  • Moisture
  • Detergent residue
  • Lint and debris
  • Hair
  • Skin cells
  • Mould spores and bacteria

Left unchecked, this build-up causes bad smells, black or pink mould growth, and even damage to your machine. That’s why regular washing machine maintenance should include knowing how to clean washing machine rubber seal.

How Often Should You Clean It?

For UK households, especially those in damp areas or with frequent laundry use, aim to clean the seal:

  • Every 2 weeks for busy homes
  • Monthly for light to moderate use
  • Immediately if you notice visible mould or smells

How to Clean Washing Machine Rubber Seal: What You’ll Need

To clean your washing machine’s rubber seal effectively, gather:

  • White vinegar or lemon juice
  • Bicarbonate of soda (baking soda)
  • An old toothbrush or soft cloth
  • Spray bottle
  • Dry towel or microfibre cloth
  • Rubber gloves (optional)

Eco tip: These eco-friendly cleaning methods avoid harsh chemicals and are safe for both your appliance and the environment.

Step-by-Step: How to Clean Washing Machine Rubber Seal

Step 1: Open the Door and Inspect the Seal

Look for:

  • Black or pink spots (mould/mildew)
  • Debris, pet hair, detergent gunk
  • Cracks or wear in the seal

Gently pull back the folds of the rubber door gasket to check hidden areas.

Step 2: Wipe Away Loose Debris

Use a dry cloth or tissue to remove any loose dirt, hair, or soap scum before applying cleaning solutions.

Step 3: Apply Natural Cleaning Solution

In a spray bottle, mix:

  • 1 part white vinegar
  • 1 part warm water
  • A squeeze of lemon juice (optional for scent)

Spray generously into the folds of the seal and leave it for 5–10 minutes.

For deeper cleaning, sprinkle bicarbonate of soda directly onto areas with visible mould.

Step 4: Scrub the Seal

Use an old toothbrush or a soft cloth to gently scrub the gasket — focusing on folds, crevices, and corners where mould hides.

This helps remove mildew without damaging the silicone rubber seal.

Step 5: Wipe Clean and Dry Thoroughly

Rinse your cloth in clean water and wipe away any remaining residue.
Dry the gasket completely with a towel — moisture left behind can restart mould growth.

How to Clean Washing Machine Rubber Seal: Prevent Future Buildup

Keeping your seal clean is easier than constantly scrubbing it. Here’s how to clean washing machine rubber seal and how to prevent build-up in the first place:

  • Leave the door ajar after every wash to allow air to circulate
  • Dry the seal after each use with a towel
  • Run a monthly hot wash cycle (60°C or higher) with vinegar
  • Use non-bio or low-suds detergent to avoid soap scum
  • Avoid using too much fabric softener
  • Clean the machine’s filter regularly

By following these washing machine maintenance tips UK households can extend the life of the seal and the appliance itself.

Can the Seal Be Too Far Gone?

Yes — sometimes, cleaning isn’t enough. Signs you may need to replace the gasket include:

  • Tears or cracks in the rubber
  • Mould that keeps returning even after cleaning
  • A leaking door
  • Persistent odour

How to Clean Washing Machine Rubber Seal FAQs

Q1: Is bleach safe for cleaning the washing machine rubber seal?
A1: While bleach is effective, it can degrade the rubber over time. For most UK homes, vinegar and bicarbonate of soda are safer and more sustainable alternatives.

Q2: What causes mould on the rubber seal?
A2: Mould grows due to trapped moisture, detergent build-up, and lack of airflow. It’s especially common in colder UK climates or during winter.
