How to Clean Washing Machine – Complete Guide for a Fresh, Odour-Free Appliance

A washing machine that smells musty or leaves clothes less than fresh is a common household frustration. The cause is often a buildup of detergent residue, mould, and limescale. While many people reach for commercial cleaning products, a simple combination of white vinegar and baking soda can be just as effective for removing odour and light buildup. This guide explains how to clean your washing machine thoroughly, with step-by-step instructions for the drum, rubber seal, detergent drawer, and filter. For a similar deep clean on your kitchen appliance, see our guide on how to clean a dishwasher.

Keeping your machine clean is about more than just eliminating smells. Regular maintenance can prevent expensive repairs and extend the lifespan of your appliance. In the UK, where hard water is common in many areas, taking care of your washing machine is particularly important.

How to Clean a Washing Machine with Vinegar and Baking Soda

• Cleaning with vinegar and baking soda is effective for odour but may not remove all limescale; use citric acid for hard water areas.
• The rubber seal is the dirtiest part – clean it separately every 2-4 weeks.
• Many UK manufacturers advise against using vinegar too often as it can degrade rubber seals over time.
• A dishwasher tablet can clean the drum but may not reach the filter or drawer.
• Leaving the door open after every wash is the single most effective prevention tip.

How to Clean the Washing Machine Rubber Seal (Door Gasket)

The rubber seal on a front-load washing machine is the main area where moisture becomes trapped. This creates an ideal environment for mould and mildew. Cleaning it regularly is key to preventing odours.

Why the Rubber Seal Gets Dirty and Smelly

Lint, detergent residue, and water collect in the folds of the seal. Over time, this mixture encourages the growth of black mould. The smell it produces is often the first sign of a problem.

Step-by-Step: Cleaning with Vinegar and a Toothbrush

Spray or wipe white vinegar onto the rubber seal and scrub gently with a cloth or an old toothbrush. For stubborn areas, a paste made from bicarbonate of soda and water can be used. After scrubbing, wipe the seal dry thoroughly.

How to Prevent Mould Build-Up on the Seal

The simplest method is to wipe the seal with a dry cloth after every wash. Leaving the door ajar allows the seal to air-dry completely, which stops mould from forming in the first place.

How to Clean a Washing Machine (UK Specific Guide)

In the UK, factors like hard water and specific brand models mean that a one-size-fits-all approach may not work. Understanding what your machine needs is the first step.

UK-Specific Products (Soda Crystals, Dr. Beckmann, OxiClean)

For UK households, products like soda crystals, Dr. Beckmann Service-It, and OxiClean Washing Machine Cleaner are popular options. Soda crystals can be used similarly to baking soda for deodorizing and cleaning.

How to Clean a Beko Washing Machine (Common Models)

Beko recommends checking your machine’s manual before using any cleaning product. In some cases, they advise using only their branded cleaner or plain hot water to avoid damaging internal parts.

How to Clean a Hotpoint Washing Machine (Step-by-Step)

The official Hotpoint UK blog recommends running an empty hot cycle occasionally for maintenance. They advise against using vinegar too frequently, as it may affect the rubber seal over time. Check the manufacturer’s instructions before cleaning.

How Often Should You Clean a Washing Machine?

The frequency of cleaning depends on how often you use the machine and what you wash. A general routine helps prevent the buildup of odour and residue.

Recommended Cleaning Schedule (Monthly, Quarterly, Yearly)

A common recommendation is to run a deep clean every month or roughly every 30 cycles. LG says cleaning every few months is sufficient for many households. More frequent cleaning may be needed if you wash pet bedding, sports gear, or heavily soiled clothes.

Daily Habits to Prevent Odour and Mold

After each wash, wipe the rubber seal, leave the door open, and remove any lint or debris from the drum. Don’t leave wet laundry sitting in the drum for long periods.

When to Call a Professional for Servicing

If your machine develops a persistent smell after cleaning, or if it starts to leak or not drain properly, it may be time to call a technician. A clogged filter or a buildup of mould can lead to more serious issues.

Alternative Methods: Dishwasher Tablets, Commercial Cleaners, and Bleach

Beyond vinegar and baking soda, several other methods exist. Each has its own pros and cons.

Using a Dishwasher Tablet: Pros, Cons, and How-To

A dishwasher tablet can be run on a hot cycle in an empty machine to clean the drum. However, some manufacturers warn against this method, as the tablet may not dissolve fully and can leave residue. It is unlikely to clean the filter or drawer effectively.

Using Bleach: Safety Guidelines and Instructions

Bleach can be effective for killing mould and bacteria. It should only be used in a hot cycle and never mixed with vinegar or ammonia. A thorough rinse cycle is essential to remove any leftover bleach odour.

Timeline for Cleaning Your Washing Machine

Following a schedule helps ensure all parts of the machine stay clean and functional.

1. After each wash: Wipe rubber seal, leave door open, remove any debris.
2. Weekly: Clean detergent drawer with hot water and brush.
3. Monthly: Run empty hot cycle with vinegar (or commercial cleaner).
4. Every 3 months: Clean filter and drain pump (refer to manual).
5. Every 6 months: Deep clean rubber seal with bleach solution if mould persists.

What Is Certain and What Remains Unclear About Cleaning Methods

Understanding what is known and what is still debated can help you make an informed choice.

Why These Cleaning Methods Work

The acidic nature of vinegar helps dissolve soap scum and mineral deposits. Baking soda acts as a mild abrasive and a deodorizer. Running a hot cycle helps loosen grime and reduce the bacteria that cause smells. A common mistake is using too much vinegar or not rinsing thoroughly, which can lead to a lingering odour later. In UK hard water areas, a descaling agent like citric acid may be needed more often.
