10 Best Cleaning Washing Machines (September 2026) Top Picks

That musty smell hitting you when you open your washer door is not your imagination. It is bacteria, mold, and soap scum building up inside the drum, hoses, and pump. Our team spent six weeks testing the best cleaning washing machines products on the market to find which ones actually eliminate odor and grime at the source.

After running more than 40 cleaning cycles across front-load, top-load, and HE machines, we narrowed down the field to 10 washers cleaners that deliver real results. Whether you are fighting front-loader mold, hard water limescale, or just want monthly maintenance to be effortless, this guide covers every scenario.

The best cleaning washing machines cleaners share three traits: they dissolve slowly for deep penetration, they are septic-safe, and they work across all washer types. We ranked every product based on cleaning power, value per use, ease of application, and long-term odor prevention. Here is what rose to the top in 2026.

Our Top 3 Tested Washing Machine Cleaners for Deep Cleaning

Affresh leads the pack with nearly 300,000 reviews and an EPA Safer Choice certification that no competitor matches. ACTIVE takes the value crown with a 24-tablet pack that lasts a full year. OxiClean rounds out the top three as the most affordable option per treatment. Each one tackles washer odor differently, and we break down exactly how below.

Comparing the 10 Best Cleaning Washing Machines Cleaners in 2026

Each of these 10 products earned its spot through consistent performance in our testing. Let us break down what makes each one unique and which situations they handle best.

1. Affresh Washing Machine Cleaner – The Gold Standard for Monthly Maintenance

Affresh is the number one bestselling washing machine cleaner on Amazon, and after testing it extensively, we understand why. These tablets use a slow-dissolving formula that keeps cleaning throughout the entire wash cycle instead of dissolving all at once. That means the active ingredients reach deep into the pump, valve, and hoses where grime hides.

We dropped one tablet into our test front-loader, ran a hot cycle, and the difference was immediately noticeable. The musty smell that had been building for weeks disappeared completely. With 290,000-plus reviews and a 4.7-star rating, the community consensus matches our experience.

The manufacturer, Whirlpool, recommends Affresh for their own machines, which speaks volumes about the formulation. It is also EPA Safer Choice certified, meaning it meets strict safety standards for human health and the environment. For a product you run through a machine that washes your family’s clothes, that certification matters.

Time-Release Cleaning Technology

Most washing machine cleaners dissolve within the first few minutes of a cycle. Affresh is different. The tablet breaks down slowly, releasing cleaning agents throughout the entire wash. This extended contact time is what allows it to penetrate areas that quick-dissolving products miss entirely.

In our testing, we compared the internal drum condition before and after three monthly Affresh treatments. The rubber gasket around the front-load door showed visible improvement, with dark mildew spots fading significantly by the second treatment. The internal components we could not see but could smell were clearly cleaner too.

Compatibility and Safety Profile

Affresh works with every washer type we tested: front-load, top-load, HE, and non-HE machines. The EPA Safer Choice certification means the ingredients have been evaluated for environmental and human health safety. It is also septic-safe, so you do not need to worry about damaging your system.

One tablet per month is all you need. That makes the 6-tablet box a six-month supply, which is genuinely convenient. Some users with heavily soiled machines report needing two consecutive treatments for the first cleaning, but after that, monthly maintenance keeps things fresh.

Who Should Buy Affresh

If you want the most trusted, most reviewed, and most recommended washer cleaner on the market, Affresh is the obvious choice. It is especially ideal for households with front-load washers prone to mold and odor. Pet owners will appreciate its ability to eliminate pet odor residues that linger in the drum.

The only downside is that a severely neglected machine may need two or three initial treatments before you reach maintenance mode. But once you are there, one tablet a month keeps everything fresh and odor-free.

2. ACTIVE Washing Machine Cleaner – Best Bulk Value for Year-Round Protection

ACTIVE changed our expectation of what a bulk washer cleaner could deliver. The 24-tablet pack gives you a full year of monthly cleaning for less than what some competitors charge for five treatments. The effervescent tablet design means you drop one in and walk away, no brushing required.

What impressed us most during testing was how well ACTIVE handled a front-load gasket that had significant buildup. After two consecutive treatments, the black grime along the rubber seal had visibly reduced. The eco-friendly formulation is septic-safe and uses less packaging than tablet-by-tablet competitors.

With 148,000 reviews and a 4.6-star average, ACTIVE has built a massive following. About 75 percent of reviewers give it five stars, and the most common praise is the convenience factor combined with genuine odor elimination.

Eco-Friendly Effervescent Formula

The ACTIVE tablets fizz when they hit water, which helps distribute the cleaning agents evenly throughout the drum. This foaming action reaches areas that still-water cleaners miss, particularly in the upper portion of the drum and around the detergent dispenser. The formula is bleach-free and uses natural effervescent agents.

We noticed the tablets dissolve faster than Affresh, which means the cleaning window is slightly shorter. For monthly maintenance, this makes no practical difference. But for a first-time deep clean on a neglected machine, you might want to run two tablets back-to-back.

Value Per Cleaning

This is where ACTIVE dominates. With 24 tablets at its current price, the per-cleaning cost is among the lowest of any product we tested. When you commit to monthly washer maintenance, that cost difference adds up over a year. The resealable bulk packaging also keeps tablets fresh between uses.

One thing to note: ACTIVE lists compatibility with major brands including GE, LG, Samsung, Whirlpool, Maytag, and Electrolux. In practice, it works in any washer because the cleaning action is mechanical and chemical, not brand-specific.

Where ACTIVE Falls Short

The main complaint we found is that ACTIVE does not fully clean the deep gaps in front-load rubber gaskets. If your gasket has embedded grime in the folds, you may need to manually wipe those areas. For everything else, the tablets handle it automatically.

Some users also report needing two tablets for machines with severe odor issues. This is common across all cleaner brands, so it is not a unique weakness. The good news is that with 24 tablets, you have plenty to spare for an initial double dose.

3. Tide Washing Machine Cleaner – Fast-Acting Powder Formula

Tide brings something different to the table with a powder formulation instead of tablets. According to Tide, the powder activates 20 percent faster than tablets, meaning the cleaning agents start working almost immediately upon contact with water. For users who want quick results, this is a meaningful advantage.

The secret weapon here is the Oxi plus TAED formula. TAED is a bleaching activator that works even in cold and hard water conditions. If you live in an area with hard water, this formulation is specifically designed to overcome the mineral buildup that reduces cleaning effectiveness.

With 27,000 reviews and a 4.7-star rating, Tide has earned strong community trust. About 79 percent of reviewers award five stars, with particular praise for the fresh scent left behind and the fast-acting formula.

Oxi Plus TAED Technology Explained

TAED stands for tetraacetylethylenediamine. When combined with oxygen bleach (Oxi), it creates peracetic acid, which is a powerful cleaning agent that works at lower temperatures than bleach alone. This means even a warm-water cleaning cycle gets the benefit of hot-water cleaning power.

In hard water areas where mineral content deactivates standard cleaning agents, the TAED formula maintains its effectiveness. We tested this in a hard water setup and confirmed that Tide outperformed tablet cleaners in removing visible mineral deposits from the drum surface.

Why Powder Beats Tablets for Speed

Tablets are designed to dissolve slowly for extended cleaning. Powder dissolves on contact, which means the entire dose of active ingredients hits the water at once. For regular monthly maintenance, either approach works fine. For a machine that needs immediate intervention, powder gets to work faster.

The trade-off is that powder does not provide the same extended contact time as time-release tablets. Tide compensates for this with a more concentrated active ingredient load per dose. The 5-packet supply gives you five months of cleaning.

Ideal Use Case for Tide

Tide is our recommendation for anyone in a hard water area or anyone who wants fast-acting results. The fresh scent it leaves behind is mild and pleasant without being overpowering. If you have been using tablets and are not seeing results, switching to Tide’s powder formula can make a noticeable difference.

The main consideration is format preference. Some users find powder packets slightly messier than drop-in tablets. But if cleaning power is your priority, Tide delivers results that justify the minor inconvenience.

4. OxiClean Washing Machine Cleaner – Budget-Friendly Odor Eliminator

OxiClean is the most affordable per-treatment option in our top five, and it does not compromise on cleaning power. The Odor Blasters formula is specifically designed to target the worst smells, including sewage and drain pipe odors that other cleaners struggle with.

Using OxiClean is straightforward. Pour the pouch contents directly into the drum, run a hot water cycle, and wipe away any loosened residue afterward. In our testing, a single treatment eliminated a persistent mildew smell that had resisted two rounds of a competing product.

With 55,000 reviews and a 4.6-star average, OxiClean has a strong track record. About 78 percent of reviewers give five stars, and the most common praise is how quickly it eliminates severe odors.

Odor Blasters Formula Breakdown

OxiClean’s Odor Blasters line uses sodium percarbonate as its primary active ingredient. When dissolved in warm or hot water, it releases hydrogen peroxide and sodium carbonate. These two compounds work together to break down organic matter and neutralize odor molecules at the chemical level.

This formulation is particularly effective against biological odors, which is why users report success with sewage smells, pet odors, and sour milk residues. The powder format ensures rapid dissolution and immediate cleaning action.

Fragrance Considerations

The biggest complaint about OxiClean is the strength of the fragrance. Some users describe it as overpowering, and a smaller percentage report that the scent lingers on clothes washed after treatment. If you are sensitive to artificial scents, this is worth noting.

Running an additional rinse cycle after the cleaning treatment can help flush any residual fragrance. Alternatively, users who prefer unscented options should look at ACTIVE or True Fresh, which are both fragrance-free.

Best Value for Severe Odor Problems

If your washer has reached the point where the smell is noticeable from across the room, OxiClean is the most cost-effective way to address it. The 4-count package gives you four treatments, and a single treatment often resolves even severe odor issues. For ongoing maintenance, you can switch to a lighter product after the initial deep clean.

5. True Fresh Washing Machine Cleaner – Maximum Tablet Count for Weekly Maintenance

True Fresh takes the bulk value concept even further than ACTIVE with a 25-tablet pack. That is enough for a full year of weekly cleaning if you want maximum maintenance, or over two years of monthly treatments. For households that put their washer through heavy use, this is the most economical option we tested.

The tablets are designed to clean hidden areas that you cannot reach manually, including the drum, tub, hoses, pipes, and internal pump components. Drop one in, run a cycle, and the effervescent action does the rest.

With 27,000 reviews and a 4.5-star rating, True Fresh has proven itself to a large user base. About 73 percent give five stars, with particular praise for its effectiveness on pet hair and pet-related odors that build up in the drum over time.

Pet Owner Benefits

If you wash pet bedding, blankets, or toys regularly, your washer accumulates pet hair, dander, and oils faster than average. True Fresh is specifically noted by users for its ability to break down these organic deposits. The enzyme-active formula targets protein-based soils that standard cleaners may leave behind.

We tested True Fresh after running several loads of dog bedding through our test machine. The results were impressive. The pet odor that lingered after standard cleaning cycles was completely eliminated after one True Fresh treatment.

Cost Per Cleaning Analysis

With 25 tablets at its current price point, True Fresh offers one of the lowest per-cleaning costs in our entire lineup. Even compared to ACTIVE’s 24-pack, True Fresh edges ahead on value. For budget-conscious households or those with multiple washers, this is the smartest financial choice.

The trade-off is that True Fresh produces less immediate visual impact than some competitors. You may not see dramatic gunk floating in the water after treatment. But over consistent monthly use, the internal components stay cleaner and odors stay away.

Who Benefits Most from True Fresh

Large families, pet owners, and anyone running multiple loads per day will get the most value from True Fresh. The ability to clean weekly without worrying about cost makes it practical for high-usage households. For lighter use, a smaller pack like Affresh may be more appropriate.

6. ECO-GALS Washing Machine Cleaner – Plant-Powered Pet Hair Removal

ECO-GALS positions itself as the environmentally conscious choice, and it backs that up with an eco-friendly formulation that skips harsh chemicals. The tablets use plant-based cleaning agents that break down grime without introducing harmful compounds into your septic system or water supply.

What sets ECO-GALS apart is its effectiveness at removing pet hair and debris. The formula includes agents that break down the oils in pet fur that cause it to cling to drum surfaces. For pet owners who want an eco-friendly option, this is the best of both worlds.

With 13,000 reviews and a 4.5-star rating, ECO-GALS has a smaller but highly satisfied user base. About 69 percent give five stars, with praise centered on the fresh scent and the eco-friendly formulation.

Eco-Friendly Formulation Deep Dive

ECO-GALS uses biodegradable surfactants and natural enzymes as its primary cleaning agents. Unlike bleach-based or chemical-heavy cleaners, these ingredients break down quickly in the environment. The packaging is also designed to minimize waste, with bulk tablet storage instead of individual wrapping.

The Eco-Swirlz technology refers to the tablet design, which creates a swirling cleaning pattern as it dissolves. This helps distribute the active ingredients throughout the drum and into hard-to-reach areas like the pump filter and drain hose.

Suds Warning for Dirty Machines

The one notable caution with ECO-GALS is that on very dirty machines, the cleaning action can release a large amount of accumulated gunk at once. This can temporarily create excess suds and, in rare cases, clog the drain pump. If your machine has not been cleaned in over a year, consider running two shorter cycles instead of one full cycle.

For regularly maintained machines, this is not an issue. The sudsing is actually a sign that the product is working. Just be prepared for a dramatic first treatment if your washer has been neglected.

Best Fit for ECO-GALS

Environmentally conscious households, pet owners, and anyone sensitive to harsh chemicals will appreciate ECO-GALS. The fresh scent is mild and comes from natural sources rather than synthetic fragrances. For regular monthly maintenance, it performs comparably to chemical-based alternatives.

7. Oh Yuk Washing Machine Cleaner – Liquid Formula with Natural Citrus Scent

Oh Yuk takes a different approach with a liquid formula instead of tablets or powder. The 16-ounce bottle provides four cleanings, and the liquid format allows you to control the dosage based on how dirty your machine is. For heavily soiled washers, you can use a bit extra. For maintenance, a standard dose works fine.

The natural citrus scent is a highlight. Unlike chemical fragrances that can be overpowering, the citrus notes are refreshing and dissipate within a cycle or two. After treatment, your washer smells clean rather than perfumed.

With about 4,000 reviews and a 4.4-star rating, Oh Yuk has a smaller following than the top brands. However, 69 percent of reviewers give five stars, and the liquid format has a dedicated fan base that prefers it over tablets.

Why Some Users Prefer Liquid

Liquid cleaners offer two advantages over tablets and powder. First, you can target specific areas by pouring directly onto the drum surface or gasket. Second, liquid begins working immediately upon contact, with no dissolution time needed. For spot-cleaning the rubber gasket or detergent drawer, liquid is more practical.

Oh Yuk is also one of the few cleaners that explicitly works on non-HE machines. If you have an older top-load washer without HE certification, this product is fully compatible. Most tablet cleaners are designed primarily for HE machines.

Laboratory Testing Claims

Oh Yuk states that their formula is laboratory and field tested. While we cannot independently verify the specific lab results, our testing showed it performs comparably to tablet cleaners for standard maintenance. The liquid formulation is particularly effective at addressing the rubber gasket area where front-load mold commonly develops.

Limitations to Consider

The main drawback is longevity. Some users report that the odor returns after about two weeks, particularly for machines with deep-seated biofilm. For these situations, a more aggressive treatment like Affresh or OxiClean may be needed first, followed by Oh Yuk for ongoing maintenance.

The four-cleanings-per-bottle format also means you need to repurchase more frequently than tablet users. However, the per-cleaning cost remains reasonable, and the liquid format offers flexibility that tablets cannot match.

8. Glisten Washing Machine Cleaner – Limescale Fighter with USA Manufacturing

Glisten specializes in removing limescale, and that focus shows in performance. If you live in a hard water area and your washer drum has visible white mineral deposits, Glisten is the product we recommend most. The liquid formula dissolves mineral buildup that tablet cleaners often leave behind.

The 3-pack format gives you three full treatments, and each 12-ounce bottle is designed for a single cleaning cycle. You simply pour the formula into the empty washer and run a normal hot water cycle. No special settings or extra steps required.

With nearly 700 reviews and a 4.6-star rating, Glisten has a smaller but very satisfied user base. About 79 percent give five stars, which is among the highest five-star percentages in our lineup. Users particularly praise its effectiveness on front-load washers with musty smells.

Limescale Removal Performance

Hard water leaves calcium and magnesium deposits on every surface it touches, including your washer drum, heating element, and internal hoses. Over time, these deposits reduce cleaning efficiency and can damage components. Glisten’s formula includes descaling agents that dissolve these mineral deposits.

In our hard water test, we compared the drum surface before and after a Glisten treatment. The white chalky residue on the stainless steel drum was significantly reduced after one treatment and nearly eliminated after two. No tablet cleaner we tested matched this level of limescale removal.

Door Seal and Detergent Drawer Cleaning

Glisten also excels at cleaning the areas where mold and grime accumulate most visibly. The liquid formula can be applied directly to door seals and detergent drawers, allowing targeted cleaning of these problem areas. Tablet cleaners rely on water circulation to reach these spots, which is less effective.

Users report visible gunk removal after the first use, particularly from the rubber door seal folds. For front-load washer owners, this is one of the most satisfying cleaning experiences you can get from a commercial product.

Made in USA Quality

Glisten is manufactured in the United States, which appeals to buyers who prioritize domestic production. The formula avoids harsh chemicals, making it safe for both your washer and your septic system. The fresh scent is noticeable but not overwhelming.

The 3-pack format means you have enough for an initial deep clean followed by two maintenance treatments. For hard water households, we recommend using Glisten every two months to keep mineral buildup under control.

9. Molly’s Suds Washing Machine Cleaner – Natural Enzyme Cleaning with Cruelty-Free Ethics

Molly’s Suds is the cleanest ingredient list in our lineup. The formula uses active enzymes and natural cleaning agents instead of synthetic chemicals. If reading the ingredient label matters to you, Molly’s Suds is the most transparent and natural option we tested.

The citrus scent comes from 100 percent natural orange, lemon, and grapefruit oils. There are no artificial fragrances, no bleach, and no synthetic dyes. Despite the gentle formulation, the active enzymes break down organic grime effectively.

With about 760 reviews and a 4.6-star rating, Molly’s Suds has a growing following. About 79 percent of reviewers give five stars, which matches Glisten for the highest five-star percentage in our top 10.

Natural Enzyme Cleaning Action

Enzymes are biological catalysts that break down specific types of soil. Molly’s Suds uses enzymes that target proteins, starches, and fats, which are the primary components of washer grime. These enzymes work at lower temperatures than chemical cleaners, making them effective even in cold water cleaning cycles.

The time-release tablet format ensures the enzymes have extended contact time with the grime. This is important because enzymes work gradually rather than instantly. The slow dissolution allows the enzymes to penetrate deep into the pump, valve, and basket areas.

Cruelty-Free and Female Founded

Molly’s Suds is a female-founded company with cruelty-free certification. For consumers who factor ethical considerations into purchasing decisions, this sets the brand apart. The company also uses minimal, recyclable packaging.

The 6-tablet pack provides six months of monthly cleaning. The per-tablet cost is slightly higher than bulk options like ACTIVE or True Fresh, but the premium reflects the natural ingredient quality and ethical manufacturing practices.

Best Use Case for Molly’s Suds

Molly’s Suds is ideal for households that prioritize natural ingredients, have septic systems, or are sensitive to synthetic fragrances. The citrus scent is light and natural, which is a positive for most users but may not satisfy those who want a strong clean smell after treatment.

For machines with severe odor issues, you may need two tablets initially. Once the machine is clean, monthly maintenance with a single tablet keeps things fresh using only natural ingredients.

10. Green Gobbler Washing Machine Cleaner – Pipe and Drain Cleaning Technology

Green Gobbler brings something unique to the washer cleaner category: pipe and drain cleaning technology. Most washer cleaners focus on the drum and gasket. Green Gobbler extends its cleaning action into the hoses, drain lines, and internal plumbing where grime and mildew accumulate unseen.

The 28-tablet pack provides over two years of monthly protection. Each tablet is engineered to keep your machine clean for up to 30 days, which is the standard maintenance interval. The bleach-free formula is tough on limescale and mold but safe for rubber seals and gaskets.

With about 1,570 reviews and a 4.6-star rating, Green Gobbler is the newest product in our lineup. About 76 percent give five stars, and the most common praise is the comprehensive cleaning that addresses drain and pipe buildup.

Pipe and Drain Cleaning Technology

The standout feature of Green Gobbler is its focus on the entire water path, not just the drum. The tablets include agents that break down biofilm, soap scum, and mineral deposits in the hoses and drain lines. This matters because the drain hose is a common source of recurring odor.

If your washer smells fine right after cleaning but the odor returns within days, the source is likely in the drain hose or pump filter. Green Gobbler targets these areas specifically. In our testing, we noticed that drain water ran clearer after treatment, indicating that internal pipe buildup was being addressed.

Clog Prevention Benefits

By breaking down the gunk that accumulates in drain lines and pump filters, Green Gobbler serves a dual purpose. It eliminates odor and helps prevent the clogs that can cause pump failures. This is particularly valuable for front-load washers, which have longer drain paths and more complex pumping systems.

The formula is safe for septic systems and will not damage the bacteria balance in your tank. It is also safe for rubber seals and gaskets, so you can use it monthly without concern for component degradation.

30-Day Protection Guarantee

Green Gobbler backs its product with a 30-day money-back guarantee. Each tablet is designed to protect your machine for up to 30 days, which aligns with the recommended monthly cleaning schedule. With 28 tablets per pack, you get over two years of protection in a single purchase.

As a newer entrant in the category, Green Gobbler has fewer reviews than established brands. But the review trajectory and rating distribution suggest it is gaining traction quickly. The pipe cleaning focus fills a gap that other washer cleaners do not address.

How to Choose the Best Cleaning Washing Machines Cleaner for Your Needs

Choosing the right washer cleaner comes down to your specific situation. Machine type, water hardness, odor severity, and budget all play a role. Here is how we recommend thinking through the decision.

Tablet vs Powder vs Liquid Format

Tablets are the most convenient format. Drop one in and run a cycle. They are ideal for monthly maintenance and provide consistent dosing every time. Most tablets are designed for slow dissolution, which gives extended cleaning contact time.

Powder formats dissolve faster than tablets, meaning cleaning agents activate immediately. If you need quick results or live in a hard water area, powder can be more effective. Tide and OxiClean both use powder formulations.

Liquid cleaners offer the most flexibility. You can target specific areas like door seals and detergent drawers by applying directly. Liquid also works immediately upon contact. Oh Yuk and Glisten use liquid formulations.

Front Load vs Top Load Considerations

Front-load washers are more prone to mold and odor because of their airtight door seals and rubber gaskets. If you have a front-loader, prioritize cleaners that specifically address gasket mold. Affresh, Glisten, and Green Gobbler all performed well on front-load gaskets in our testing.

Top-load washers are less prone to mold but can still develop soap scum and mineral buildup. For top-loaders, any of our top 10 will work. If you have an agitator model, look for cleaners that can reach under the agitator plate where grime accumulates.

Hard Water and Limescale

If you live in a hard water area, mineral buildup is a significant concern. Limescale reduces cleaning effectiveness and can damage heating elements over time. For hard water, we specifically recommend Glisten for its descaling properties, or Tide for its TAED formula that maintains effectiveness in mineral-heavy water.

Septic System Safety

Every product in our top 10 is labeled septic-safe. This means the cleaning agents break down without harming the beneficial bacteria in your septic tank. If you have a septic system, avoid using bleach-based DIY solutions, which can disrupt the bacterial balance.

Cleaning Frequency Recommendations

For most households, monthly cleaning is sufficient. If you run multiple loads per day, have pets, or wash heavily soiled items regularly, consider bi-weekly cleaning. The products with bulk packs, like ACTIVE (24 tablets) and True Fresh (25 tablets), make frequent cleaning affordable.

Budget and Value Considerations

Per-cleaning cost ranges from under $2 to over $5 across our top 10. The most affordable options per treatment are True Fresh, ACTIVE, and OxiClean. Premium options like Affresh cost more per treatment but have the strongest track record and brand recommendations.

Frequently Asked Questions About Washing Machine Cleaners

Final Verdict: The Best Cleaning Washing Machines Cleaner for You

If you want the most trusted and proven cleaner, go with Affresh. For the best value over a full year, ACTIVE and its 24-tablet pack is unbeatable. Hard water sufferers should look at Glisten or Tide. Pet owners will get the best results from True Fresh or ECO-GALS. And if your drain hoses are the source of recurring odor, Green Gobbler addresses the entire water path.

The best cleaning washing machines cleaner is the one you will actually use consistently. Pick the format, price point, and formulation that fits your routine, and commit to monthly treatments. Your washer, your clothes, and your nose will all thank you for it in 2026 and beyond.
