How to Deep Clean Your Washing Machine

To deep clean your washing machine, use a specialised commercial cleaner and then a bicarbonate of soda solution. This will lift excess detergent and debris and remove mould-like odours. Run your washing machine on for both cleaning agents on the hottest, longest cycle.
However, knowing how to deep clean your washing machine isn’t only about the drum. There could be mould and residue hiding in the drawer, door seal and filter. Your washing machine could be more than 10 times dirtier than your toilet seat, and 7% of people admitted they’ve never cleaned their washing machine. We recommend deep cleaning your washing machine every three months. This will ensure the cleaning itself isn’t too arduous on you and the likelihood of your washing machine reaching its life expectancy.
How to Clean Your Washing Machine Drum
Using Washing Machine Cleaners
- Measure the recommended amount of cleaner.
- Pour into either the detergent drawer or directly into the drum.
- Set the machine to the temperature recommended by the cleaner manufacturer.
- Run the washing machine with no laundry inside.
Commercial washing machine cleaners lift dirt, dissolve grime, and eliminate mould and bacteria. Each cleaner has a different chemical composition, so you must follow the instructions on the bottle. Some may have a higher bleach, citric acid, or enzyme concentration. So, using too much could incur long-term damage to your machine.
Washing machines are highly effective on their own. But if you still feel like there’s a residue in the drum, a simple solution of bicarbonate of soda will finish the job.

Using Bicarbonate of Soda
- Measure half a cup (170g) of bicarbonate of soda.
- Measure a quarter cup (85ml) of white vinegar.
- Put a couple of clean hand towels into the drum.
- Pour the bicarbonate of soda and vinegar over the hand towels.
- Set your washing machine to the hottest temperature.
- Choose the longest cycle possible on the machine.
- Run the washing machine.
Bicarbonate of soda is an alkaline. When used with vinegar, the solution neutralises odours and non-corrosively lifts dirt. It’s a respected homemade remedy that mimics commercial cleaners without abrasive effects. Still, it is vital to note that bicarbonate of soda will not kill bacteria. It may slow the regrowth of bacterial colonies, but it will not destroy the source of your mould or smell problem.
If Bicarbonate of Soda Doesn’t Kill Bacteria, Should I Use it to Deep Clean My Washing Machine?
Yes. A first cycle of specialised chemical cleaner takes care of the bacteria; bicarbonate of soda is simply a helpful complement. A two-step process ensures thorough deep cleaning of your washing machine drum and entirely removes any residue.
How to Clean Your Washing Machine Drawer
- Fill a deep bowl or sink with hot water, white vinegar, and washing-up liquid.
- Remove the drawer and any other detachable parts.
- Submerge and soak the drawer in the water for one hour.
- Put on a pair of gloves to protect your hands.
- Use a toothbrush to scrub the surface of the drawer and parts, paying attention to crevices.
- Once all dirt is detached, drain the bowl or sink and rinse the drawer and parts under hot water.
- Leave to air dry or dry thoroughly with a microfiber cloth.
How to Clean Behind & Around a Washing Machine Drawer
- If the area is mouldy, use a mould spray directly on the mould patches and let it soak.
1a. If there is no mould, wipe the area with a damp cloth to remove dirt.
- Coat a dish brush or toothbrush with washing-up liquid.
- Scrub all surfaces with the brush, paying attention to crevices.
- Dampen a second microfiber cloth and thoroughly wipe the lifted dirt and mould away.
- Dry thoroughly with a cloth and leave to air dry.
The most important thing to remember when cleaning a washing machine drawer is that moisture causes mould. So, ensuring each component and the drawer housing is completely dry will prevent fast mould regrowth. Cleaning your washing machine drawer ensures detergent travels into the drum and prevents mould from doing so.
How to Clean Your Washing Machine Door Seal
- Pull back the rubber seal gently and wipe the trapped material from underneath with a dry cloth.
- Spray the wiped area with a mild disinfectant and allow it to soak for 10 minutes.
- Use a soft bristle brush to gently scrub the disinfectant and dislodge any residue.
- Wipe the brushed area with a clean, damp cloth.
- Wipe with a dry cloth to remove leftover moisture.
When cleaning your door seal, being gentle is key. Harsh cleaners and rough scrubbing can degrade the rubber. If the rubber seal is damaged, you risk leaking and water damage in the future. It is essential to dry the seal thoroughly post-clean, as the remaining water will breed bacteria far faster than you wiped it away. We recommend leaving your washing machine door open after every cycle to encourage air circulation.

How to Clean Your Washing Machine Filter
- Place a towel underneath the filter access panel to absorb any water flow.
- Remove the filter and rinse it under hot running water.
- Scrub the crevices with a toothbrush to dislodge the gunk.
- Wipe with a dry cloth to remove leftover water.
- Leave to air dry.
How to Clean Your Washing Machine Filter Compartment
- Wipe the compartment with a damp cloth.
- Coat a toothbrush with washing-up liquid and scrub, paying attention to crevices.
- Wipe again with a second wet cloth to remove dislodged materials.
- Ensure the drain pump isn’t blocked or covered.
- Allow the area to air dry completely before reinstalling the filter.
Your filter should be thoroughly cleaned every 3 months. The filter is an integral part of your washing machine, improving drainage and protecting the pump and motor from overworking.
Deep Cleaning Didn’t Work?
Sometimes, no level of deep cleaning can restore an old washing machine. Most washing machines have a lifespan of 8-12 years. So, if you notice repetitive leaks or your clothes are still dirty after washing, it’s probably time.
It may be more cost-effective to replace your washing machine if you’re encountering problems even after deep cleaning it.
