You've found it: the ultimate guide on how to clean a washing machine. Washing machines can become a breeding ground for harmful bacteria if not cleaned regularly, not to mention the fact that, after a while, they can start to stink. To keep your washing machine fresh, sanitized, and mildew-free, give it a weekly maintenance clean; your clothes (and your nose) will thank you.
Just follow this simple step-by-step guide to foolproof washing machine cleaning.
Read your washing machine’s manual for specific cleaning instructions; some manufacturers discourage the use of de-scaling products in their machines. In some cases, this may invalidate your warranty, so check before you do anything.
1. How to clean a washing machine's detergent drawer
The washing machine detergent drawer gets surprisingly dirty for an area that's designed to hold detergent. You'll find that mold and mildew – and just gunk in general – can quickly build up, and with it, bacteria. Not a great place to start your laundry, right?
Now: To begin cleaning your washing machine, remove the detergent drawer at the front of the machine (check your manual if you need advice for how to fully remove it). Soak the drawer in hot, soapy water and, using an old toothbrush, scrub away any soap build up or mold. Rinse thoroughly, and dry with a hand towel. Before you put it back, clean out the cavity – it's likely there's some hidden mold there, too.
Later: Leave the detergent drawer open in between loads of laundry to prevent mold from growing. Use only as much detergent as is necessary, following the guidelines on the packaging; overloading detergent will create a build up inside the machine.
2. How to clean a washing machine with vinegar
Cleaning your washing machine once a month is a wise move. It will help keep your whites whiter and ensure a sweet-smelling pile of laundry.
Now: Set your machine on its hottest cycle (or a minimum of 140ºF) and pour 1C of white vinegar directly into to the drum. The vinegar is the perfect solution to help to purify your machine – it's an excellent, natural way to kill bacteria, and the smell will disappear during the rinse cycle.
Later: Keep a bottle of white vinegar handy near your washing machine – perhaps alongside your detergent. That way, you'll easily remember to keep up the cleaning routine.

3. How to clean a washing machine with baking soda
Using baking soda is one of our favorite cleaning hacks. It'll tackle washing machines with ease, but you can use it to clean everything from refrigerators to carpets, too, so having some handy is useful.
Now: Add two tablespoons of baking soda into the detergent drawer at the same time you clean it with vinegar. The soda and vinegar work together to naturally break through dirt and remove mold while cleansing and refreshing your washing machine. Start the hot cycle.
Later: Once a month run an empty hot wash to eliminate any build-up and smells, adding the baking soda and/or vinegar for extra cleaning power.

4. How to clean a washing machine with bleach
If you're a fan of cleaning with bleach, you won't balk at using it to clean a washing machine. It is, obviously, very effective at cleaning dirt and mold from both the drum and detergent drawer of the washing machine, and also the exterior.
Now: Add half a cup of bleach directly into your washing machine's drum, and half into your detergent drawer. Run an empty hot wash. If you can pause your wash once the machine has filled with water, do so for a good hour. Then start the cycle again. Run an extra rinse cycle to ensure all the bleach has been removed. Once it's finished, wipe down the inside of the door and dry out the seals.
Later: Next time you do the laundry, ensure it's a load of whites which will benefit from any leftover bleach residue rather than be damaged by it.
5. Leave the washing machine to dry
Cleaning a washing machine doesn't just involve cleaning – allowing it to dry properly is a must to prevent mold build-up in the first place.
Now: Let the cycle come to a natural finish and open the door letting the inside of the drum air-dry. If any bad smells or excess grime are lingering repeat the process again.
Later: In between washes leave the door open, or at least until the interior and drum have dried out. This reduces the chance of mold and bacteria growing inside.
6. Clean the washing machine's rubber seals
The rubber seals of a washing machine, like the detergent drawer, are a haven for mold and mildew – but you'll likely also find everything from coins to hair in there.
Now: Using a damp cloth saturated with soapy water, wipe around the rubber seals of the washing machine. Be careful when you lift them away from the metal as you may accidentally rip or unseal them. Where possible wipe away any residue that is stuck to the seal. If necessary gently remove any stubborn grime with a toothbrush.
Later: Run a hot maintenance cycle according to the washing machine manufacturer’s instructions. Each time you do the laundry, as you empty the washing machine, check that nothing has been deposited into the crevices between the seals.
The best way to stop mold growing on the seal in the future? Leave the washing machine door open for a few hours after you’ve removed a load of clean laundry to let the moisture out, and clean the seal as above regularly.
7. How to clean the washing machine's filter
The washing machine's filter, usually found beneath the drum door just above floor level, stops all the nasty stuff that gathers in the crevices too – fluff, hair and coins – from reaching the pump. So, it does an important job. But... just like the detergent drawer, it can be a great place for mold and germs to grow, which can, in turn, make your washing machine smell.
Now: Check your washing machine's instructions to find out how to remove the cover if it's fixed in place, and how to remove the filter. The user manual should also explain how to clean the filter. You may need to place a bowl or tray on a towel beneath it to catch leaks from the drain. Replace the cover carefully.
Later: Repeat this process once every three or four months and your washing machine will function so much better.

8. How to clean a washing machine's exterior
The drum in particular becomes quickly dusty, but the detergent drawer can drip, as can the drum itself during or after a wash.
Now: Using a damp cloth and dish soap, clean any stains from the outside of the washing machine and wipe away any dust. Dry the exterior with a clean kitchen towel.
Later: Keep it up – a quick, regular wipe over will be easier in the long run than a thorough annual cleaning.
9. Use your laundry detergent to clean your machine
It's perfectly fine to run a maintenance clean with laundry detergent rather than a specialized washing machine cleaner. You can use your regular detergent – although we find that what works best is a natural, plant-based detergent marked as 'concentrated'. These are typically stronger, so you don't need to use a lot of it, and they leave your washing machine sparkling clean. Our favorite is Mrs. Meyer's Laundry Soap in Lavender. It's plant-derived, concentrated, contains no phthalates or parabens and contains powerful enzymes that are up to the task of deep cleaning your machine, as well as your clothes. And it smells so, so good. It also comes in recyclable packaging.
10. Use sodium percarbonate (or washing soda) to deodorize your machine
Sodium percarbonate is also often labeled as 'washing soda,' or 'oxygen bleach' and does a really good job at freshening up and ridding washing machines of unpleasant smells.
Stronger than baking soda but safer than liquid bleach, it's a great all-around pick for your weekly maintenance clean. It comes in powder form and should be used in exactly the same way as baking soda.
11. How to stop washing machine smells
You've now cleaned your washing machine – but how do you ensure the bad smell doesn't return? These are the easiest ways to make sure that your washing machine stays fresh-smelling for longer:
- Keep the washing machine door open: this will prevent excess moisture from accumulating and mold from growing
- Avoid using too much detergent: paradoxically, too much detergent causes bad smells because it builds up inside your washing machine. Use powder detergent on occasion, even if you prefer liquid detergent
- Don't forget the hot wash: a hot wash every week will keep your washing machine smelling better than if you just do cold cycles.
- Brushing off any excess dirt from muddy clothing before putting inside your appliance will keep it as clean as possible.
- If you live in a hard water area, use a water softener attached to your in-flow pipe or put softener tablets in with your wash. Both of these will help minimize the build-up of lime scale.
- Washing machine cleaners will keep yours fresh – and keep your washing white, too.
12. How to clean a washing machine with vitamin C
There are two main ways to try and get rid of buildup in your washing machine: one is with an alkaline substance such as baking soda. Baking soda's high ph makes it perfect for cutting through greasy and oily stains, making it very effective in kitchens. However, if you live in a hard water area, you may have noticed that cleaning your washing machine with baking soda isn't doing a lot.
If that's the case, it's time to try the opposite – acidic – approach. Citric acid and ascorbic acid (commonly known as vitamin C) are reducing or chelating agents, which makes them particularly effective for cleaning buildup associated with hard water – rust, limescale, and soap scum or detergent buildup.
Bring a pan of water to the boil, take off the heat, and dissolve approximately 3/4 cup of ascorbic acid powder and 1/2 cup of citric acid powder in the water. Add the warm solution directly to the drum of your machine and pour a little into the tray. Run the machine on a hot wash without any clothes. Don't use citric acid undiluted on plastic washing machine trays as it could cause damage.
13. How to get rid of limescale in the washing machine
White vinegar will once again work wonders for this job. Add a large cup to the detergent drawer and run a hot wash cycle. Keep your clothes out of the equation for this load, of course.
