If your clothes aren't smelling as fresh as they used to, or you've noticed that your once-brilliant washing machine has begun to struggle to remove dirt and stains, you might need a washing machine cleaner. Yes, even washing machines need cleaning from time to time: build-up of bacteria, grime, lint and other waste accumulates in the machine's drum, so even fresh washing can become quickly dirty on contact.
Even the best washing machines are prone to dirt build-up, which inevitably leads to unpleasant odours that permeate your clothes, the machine itself, and eventually your kitchen. Improve hygiene and leave washing smelling fresh and invigorating with the very best washing machine.
But what washing machine cleaner should I pick? Though you might be tempted to opt for a cheaper, all-purpose washing machine cleaner, you're unlikely to solve the problem with a product that's not designed to sort it. You might have mould and mildew, limescale or even residue from previous detergent washes, all of which need a certain washing machine cleaner, and that's why we're here.

Best overall
Perfect for long-lasting washing machine freshness, the Calgon four-in-one cleaner is ideal for a thorough, cost-effective clean.
Neatly packaged into individual tablets for consistent cleaning, the Calgon four-in-one washing machine cleaner tackles all dirt, limescale and mould quickly and effectively, offering a faultless, odour free finish.
Once clean, however, the Calgon four-in-one washing machine cleaner doesn't have a fragrance whatsoever, so you're not getting the satisfying freshness that you might get with other products. For some, this is a blessing in disguise as washing machine cleaners can smell overly potent, but it's something to bear in mind while buying.
A fantastic product that's long-lasting and performance-boosting, the Calgon four-in-one washing machine cleaner is a great product that's ideal for everyone.
Pros
- Incredibly effective all-purpose cleaning
- Ideal for energy-efficient washing machines
- Lasts for over three years
Cons
- No scent after cleaning
Formulation type: | Tablet |

Size: | 585g |
Best budget
A fantastic low-budget option, Dettol's five-in-one washing machine cleaner is capable of tackling mould, limescale and detergent residue with ease, all while keeping your machine fresh.
To be used every two months, this incredibly affordable liquid washing machine cleaner will last up to a year with careful usage, making it one of the best value cleaning products on the market right now. This all-in-one solution to washing machine troubles is incredibly cost-effective and capably conquers all manner of dirt and grime without a hitch.
Our only dislike with the Dettol washing machine cleaner is its lack of eco-friendliness. Containing Benzalkonium chloride, a form of antiseptic, this substance is quite harmful to the environment, particularly in water, so it's certainly worth considering if you're environmentally conscious.
That being said, the Dettol washing machine cleaner is the perfect all-purpose solution for those struggling with dirt build-up. This potent cleaner can tackle anything you throw at it, and leaves your washing machine smelling fresh and clean whilst doing so.
Pros
- Powerful all-purpose cleaning
- Long-lasting cleaning solution that's suitable for any washing machine
- Incredible value
Cons
- Not very eco-friendly
Formulation type: | Liquid |
Effective against: | Limescale, antibacterial, hidden dirt, mould and mildew |
Compatibility: | All washing machines |

Best eco-friendly cleaner

Suppose we were to note any areas for improvement. In that case, we'd certainly state that this eco-friendly option isn't as effective as other options - it's a powerful way of tackling limescale. Still, it's not as effective as some less environmentally sustainable options.
That being said, for the price, and its longevity, the Ecoegg is the perfect way to maintain a washing machine over time, and it will keep your washing and the machine itself smelling fresh.

Best high-powered cleaner
Potentially the most powerful washing machine cleaner on the market, the HG Deep Clean washing machine cleaner is suitable for those looking to give their older machine a total cleanse. Perfect for blasting away grime and dirt build-up from years of use, the HG Deep Clean washing machine cleaner is a tough descaler and antibacterial, leaving your washing machine cleaner than ever before.
With only two packets included, this washing machine cleaner is designed to be used every three months, which is a lot less frequent and more convenient than other options, but at £2 per use, it's a pricey method of cleaning your washing machine.
But you're ultimately paying for a powerful washing machine cleaner, and that's precisely what you get: the most effective washing machine cleaner on the market, you cannot beat the HG Deep Clean for a total system cleanse.
Pros
- Powerful descaler
- Incredibly effective at total drainage cleaning
- Keeps your washing machine running at its best

Size: | 200g |
Best non-chemical cleaner
A brilliantly cost-effective washing machine cleaner, the environmentally friendly Magnozone ball is a simple design that specifically targets limescale. Using magnets, the Ecozone Magnoball is used during a clothes wash, where it bounces and collects limescale, preventing it from building up inside the drum of the washing machine and in the pipes.
An effective solution for maintaining a washing machine, but not an immediate solution to cleaning long-term limescale build-up, the Ecozone Magnoball is a great option for cutting back on spending and helping out the planet, thanks to its total lack of used-up harmful chemicals.
A brilliant alternative to cleaning your washing machine, use the Magnoball up to five times before seeing results, you won't regret it.
Pros
- Effective limescale descaling for up to five years
- Incredibly good value for up to five years of use
- Excellent for long-term maintenance
Cons
- Not effective at descaling pipes
Formulation type: | Magnetic ball |
Effectiveness: | Limescale |
Compatibility: | All washing machines |
Frequency of use: | Leave in washing machine for up to five years |
Size: | 100g |
Best washing machine cleaner for hair
One of the more potent washing machine cleaners on the market, Vamoosh is a fantastic solution to cleaning your washing machine in a pinch, and it's incredibly affordable too.
Use to dissolve even hair from your washing machine, this is the be-all-end-all washing machine cleaner, perfect for defeating even the toughest of limescale buildup, along with mould and mildew.
Our only gripe with the Vamoosh washing machine cleaner is its sheer chemical potency, which simply can't be good for the environment. We'd certainly recommend using it with caution as it can cause serious irritation if it contacts your eyes.
The Vamoosh six-in-one washing machine also has a fresh lemon scent, leaving your washing machine smelling perfectly divine after you're finished. Leave on the hottest cycle with the washing machine cleaner in the dispenser drawer and watch the magic happen.
Pros
- Incredibly strong washing machine cleaner
- Perfect for dissolving hair and other drain buildup
- Leaves washing machine smelling fresh
Cons
- Very chemically harmful
Formulation type: | Powder |
Effectiveness: | Limescale, antibacterial, hidden dirt, mould and mildew, and hair |
Compatibility: | All washing machine |
Frequency of use: | Use every one to two months |
Size: | 175g |
Best for multiple appliances
The perfect solution for an array of kitchen appliances, the Care and Protect power pod descaler and degreaser is fantastic for those struggling with grease in their washing: cutting through it can be a challenge, but it's not impossible, especially with the right washing machine cleaner.
Excellent for tackling mould, dirt, limescale and especially grease, the Care and Protect triple power pod is simply brilliant for any washing machine, and works well even at low temperatures, unlike most washing machine cleaners.
We'd recommend the Care and Protect washing machine cleaner even more if it were a little more cost-effective: yes, it lasts for up to six months, but many other options offer longer washing machine coverage at a similar, if not lower cost - which is something to bear in mind if you're on a budget.
Pros
- Powerful degreasing cleaning
- Useful for both washing machines and dishwashers
- Ideal for energy-efficient washing machines
Cons
- Small six-pod supply
Formulation type: | Liquid pods |
Effectiveness: | Limescale, antibacterial, hidden dirt, mould and mildew, and grease |
Compatibility: | All washing machines |
Frequency of use: | Up to six months |
Size: | 150g |
Best for long-lasting washing machine cleaning
A great way of saving money in the long run, buying in bulk is of course a well-known method of cutting back costs, and the Pro-Kleen washing machine cleaner is precisely that. At five litres, you've got a huge amount of washing machine cleaner for a low price, and it's incredibly effective too.
Fresh-smelling and long-lasting, clean your washing machine every month or between 30 washes, and you'll have a clean-smelling washing machine for over four years with this affordable investment into cleaner washing.
Handling a five-litre jug of harmful chemicals might not be for everyone, especially for older users - it's a heavy, bulky and obtrusive container for a washing machine cleaner which you'll end up using every now and then, so it's better if you've got a great amount of space for cleaning products, the space under your sink may not suffice.
An effective, powerful cleaning solution against limescale, grease and mould, the Pro-Kleen washing machine is an ideal method of keeping dirt at bay and your washing as fresh as can be.
Pros
- Huge 50 servings size
- Smells fresh and offers solid cleaning
- Ideal for tackling grease and limescale
Cons
- Not the most environmentally friendly
Formulation type: | Liquid |
Effectiveness: | Limescale, antibacterial, hidden dirt, mould and mildew, and grease |
Compatibility: | All washing machines |

Size: | 5 litres |
Best for limescale prevention
www.tesco.com
For those dealing with limescale problems, Tesco's excellent limescale prevention gel is an ideal washing machine cleaner that's readily available and very cheap.
Pour into the dispenser drawer alongside your laundry detergent and dissolve any pesky limescale build-up in a flash. Since Tesco's Limescale prevention gel is suitable only for tackling limescale, the chemicals aren't harmful to clothing, so they can be used alongside a wash, which is fantastic for cutting back on energy bills.
Of course, this gel solution isn't a total fix for all of your washing machine's problems and acts largely as a preventative measure, so it's not ideal for total cleansing if you've already got a problem, which is worth bearing in mind when buying.
But for a gentle, non-toxic washing machine cleaner to be used alongside your washing, you cannot beat this fantastic limescale prevention gel from Tesco.
Pros
- Powerful anti-limescale solution
- Cheap and effective
- Long-lasting liquid
Cons
- Only effective at limescale prevention
Formulation type: | Liquid |
Effectiveness: | Limescale |
Compatibility: | All washing machines |
Frequency of use: | Once per month |

The best washing machine cleaners: buyer's guide
How do washing machine cleaners work?
Washing machine cleaners contain powerful anti-bacterial substances, as well as descaling agents that cut through limescale build-up and reduce dissolved odour-causing substances in your washing machine's drum and drainage.
By eliminating these odour-causing residues, your washing machine is left smelling fresh and more effective at cleaning.
Why does my washing machine smell?
Washing machines begin to smell due to a number of factors: the primary cause of bad smells in a washing machine is the result of bacteria, mould and mildew build-up. Damp and warm, washing machines are the ideal environment for bacteria to flourish, and flourish it certainly does. Even after a day or two after use, your washing machine's excess moisture will begin to smell mildew, and so too will your kitchen if you don't solve it.
How often should I clean my washing machine?
Depending on the solution you're using, washing machines need to be cleaned once every one to three months to ensure optimal running and no smells are building up.
It's recommended you keep up on washing machine cleaning to keep your drainage and washing machine drum free of residue, which ultimately ends up on your clothes, leading to unpleasant smells.
FAQs
What's the best washing machine cleaner?
While there is no definitive answer, we certainly have our favourites: Calgon's tablet washing machine cleaner is fantastic for busting grease, limescale and dirt buildup, and it's long-lasting too. For a more thorough clean, however, we cannot help but recommend HG Deep Clean and service: a fantastic cleaning solution to your washing machine woes.
How does hard water affect my washing machine?
Hard water affects most of the UK, and it's a bit of a problem. High mineral content in the water causes the buildup of limescale, a tough substance that accumulates in pipes, leading to less effective draining and therefore less efficient washes.
To combat this, you need a washing machine cleaner to break down these minerals, especially limescale.
Are washing machine cleaners harmful to the environment?
Not all, but many washing machine cleaners are harmful in water, which is why they should be used carefully and sparingly. These harmful chemicals aren't ideal, but environmentally friendly options aren't quite as effective at cleaning. We'd certainly suggest opting for something eco-friendly wherever you can.
