8 Best Washing Machine Cleaner (May 2026)

The table below compares all eight cleaners we tested across key factors like price per use, cleaning method, and special features.

Detailed Washing Machine Cleaner Reviews

1. Affresh Washing Machine Cleaner – Best Overall

Affresh stands out as the most thoroughly tested and manufacturer-backed option on the market. As Whirlpool Corporation’s official washer cleaner, it’s formulated specifically to target the areas where buildup occurs most frequently in your machine.

The time-release tablet technology is what makes Affresh particularly effective. Unlike quick-dissolving powders that wash away before completing their job, these tablets slowly break down throughout the entire wash cycle, continuously cleaning the pump, valve, and hoses where odor-causing bacteria hide.

I tested Affresh in a front-load washer that had developed a persistent musty smell despite regular maintenance. After one cycle with Affresh, the difference was noticeable. Two treatments over two weeks completely eliminated the odor that had been plaguing our laundry for months.

The tablets are incredibly simple to use. Just place one tablet directly in the washer drum, not the dispenser, and run a normal cycle with hot water. No measuring, no mess, and no residual cleaning product to worry about affecting your next laundry load.

Why Affresh Works So Well

The slow-dissolving formula allows the cleaning agents to penetrate deep into internal components that standard cleaning methods miss. The tablet continues working throughout the entire wash cycle, reaching areas where water alone cannot effectively clean.

Who Should Buy?

Choose Affresh if you want the manufacturer-recommended solution with proven effectiveness across all washer brands. It is ideal for anyone dealing with persistent odors or as a preventive maintenance tool for your washing machine investment.

Who Should Avoid?

Look elsewhere if you need the most economical option or prefer a faster-acting liquid formula. The per-use cost is higher than bulk alternatives, and tablets take longer to dissolve than liquid options.

2. OxiClean Washing Machine Cleaner – Best Budget Pick

OxiClean brings their signature oxygen-based cleaning technology to washing machine maintenance at the most budget-friendly price point among major brands. At just $1.42 per use, it offers powerful cleaning without the premium cost.

The powder packet format dissolves quickly in water, releasing oxygen-based cleaners that break down odor-causing residues throughout your washer. I found the OxiClean formula particularly effective at removing soap scum and detergent buildup that can trap bacteria.

During testing, OxiClean performed remarkably well on fresh odors. For a washer with mild smells or monthly maintenance, this cleaner gets the job done efficiently. The packets are pre-measured, eliminating the mess and guesswork of powder cleaners.

Oxygen-Based Cleaning Power

The Odor Blasters formula uses oxygen ions to penetrate and break down organic matter. This approach is gentler on machine components while still delivering strong cleaning performance against common washer odors.

Who Should Buy?

OxiClean is perfect for budget-conscious shoppers who want a trusted brand name without paying premium prices. It works especially well for monthly maintenance in washers without severe odor problems.

Who Should Avoid?

Consider other options if you need a year supply at once or have heavily neglected machine maintenance requiring multiple intensive treatments.

3. Tide Washing Machine Cleaner (5-Pack) – Brand Trust Winner

Tide leverages its position as America’s most trusted laundry brand with a washing machine cleaner that combines their expertise with Oxi cleaning power. The result is a product that delivers on brand promise with strong odor elimination.

The powder formula contains Oxi additives specifically designed to power away residue and odor-causing bacteria. I found this cleaner particularly effective against fabric softener buildup, a common issue that many other cleaners struggle with.

Testing revealed excellent results in both front-load and top-load machines. The Tide formulation dissolved completely without leaving powder residue, a problem I’ve encountered with some generic powder cleaners. The 5-month supply packaging is convenient for most households.

Why Choose Tide?

The combination of Tide’s laundry expertise and Oxi technology creates a cleaner that understands laundry soils and residues. This formulation targets exactly what builds up in your machine from regular detergent use.

Who Should Buy?

Select this cleaner if you trust the Tide brand and want a product from a company that understands laundry inside and out. It is excellent for regular maintenance of washers used with Tide products.

Who Should Avoid?

Pass on this option if you are looking for the best value or prefer tablet form over powder. The higher per-use cost may not justify the brand recognition alone for budget shoppers.

4. Tide Washing Machine Cleaner 10-Month Supply – Best Value Pack

This extended supply package offers the best value among Tide options, reducing the cost per use significantly compared to the 5-count package. The 10-month supply ensures you have cleaner on hand for regular maintenance.

What sets this package apart is the included calendar reminder sticker. This simple addition helps you stay consistent with monthly cleaning, which I found is the key to preventing odor problems before they start.

The same powerful Oxi formula provides deep cleaning action, dissolving detergent residue and eliminating odors at the source. With a 4.7-star rating from nearly 7,000 reviews, customer satisfaction is exceptionally high for this extended supply option.

Convenience Factor

Having a 10-month supply means you never run out unexpectedly, and the calendar reminder ensures you stay on schedule. Consistency is crucial for washer maintenance, and this package makes it easy.

Who Should Buy?

This package is ideal for busy households who want to buy in bulk and set up a routine. The calendar reminder alone makes it worthwhile for anyone who forgets monthly maintenance.

Who Should Avoid?

Look for alternatives if you prefer tablet form or want to try a cleaner before committing to a 10-month supply.

5. 24-Pack Descaler Tablets – Best Year Supply

This 24-tablet package offers exceptional value with a full year of cleaning at less than half the cost per use of premium brands. The standout feature is the descaling formula, making it particularly effective for homes with hard water.

Hard water leaves mineral deposits that standard cleaners may miss. This descaling formula specifically targets those mineral buildups while also removing detergent residue and odors. I noticed significantly better results in areas with hard water compared to standard cleaners.

The eco-friendly, biodegradable formula is safe for septic systems and breaks down without harsh chemicals. Each tablet provides a complete cleaning cycle for all washer types, including high-efficiency models.

Hard Water Solution

Mineral scale from hard water can reduce washer efficiency and cause odors. The descaling agents in these tablets dissolve limescale and mineral deposits that other cleaners leave behind.

Who Should Buy?

This is the perfect choice for households with hard water or anyone wanting a full year supply at an excellent price point. The eco-friendly formulation appeals to environmentally conscious consumers.

Who Should Avoid?

Consider name-brand options if manufacturer endorsement is important to you or if you prefer products with extensive review history and brand recognition.

6. True Fresh Washing Machine Cleaner – Best for Pet Owners

True Fresh addresses a specific problem that pet owners face: pet hair, dander, and the distinctive odors that come with our furry friends. This formula is specially designed to tackle these challenges while providing standard washer cleaning benefits.

The 25-tablet supply offers exceptional value at under $0.78 per use, making it one of the most economical options available. During testing, I found this cleaner particularly effective at removing trapped pet hair from washer components that regular washing leaves behind.

Tablet format means no measuring or mess. Each tablet is pre-measured for consistent cleaning power. The septic-safe formula is environmentally friendly and safe for all plumbing systems.

Pet-Specific Formulation

Pet dander and hair create unique cleaning challenges in washing machines. This formula contains enzymes and surfactants designed specifically to break down these pet-related residues while eliminating associated odors.

Who Should Buy?

Pet owners dealing with pet hair in their washer or lingering pet odors on their laundry will benefit most from this specialized formula. The excellent value is an added bonus.

Who Should Avoid?

Non-pet owners may not need the specialized pet formula and could opt for general-purpose cleaners at similar price points.

7. ACTIVE Enzymatic Cleaner – Best Enzymatic Formula

ACTIVE takes a different approach with an enzymatic formula that breaks down organic matter at the molecular level. This makes it particularly effective against biological odors that standard cleaners may only mask rather than eliminate.

The enzyme-based formula targets the source of odors by digesting the organic material that bacteria feed on. This approach means longer-lasting results rather than temporarily covering up smells. I found this cleaner especially effective for musty odors that had persisted despite other treatments.

At $0.56 per use, this is one of the most economical options available. The 24-tablet supply provides a full year of monthly cleaning treatments in a convenient, mess-free tablet format.

How Enzymes Work

Enzymes are biological catalysts that break down organic compounds like proteins, fats, and oils. This means they digest the source of odors rather than just perfuming over them, resulting in more thorough and lasting cleaning.

Who Should Buy?

Pet owners dealing with accident odors, anyone with persistent musty smells, or households preferring enzymatic cleaning products will benefit most from this formula.

Who Should Avoid?

If you prefer immediate fragrance or faster-acting chemical cleaners, this enzymatic option may not meet your expectations as enzymes work more gradually.

8. Washing Machine Cleaner 24-Pack – Best Budget Year Supply

This 24-pack offers the absolute lowest cost per use among all options reviewed, making it an attractive choice for budget-focused shoppers. At just $0.42 per tablet, you get a full year of monthly cleaning for under $10.

The tablets provide solid cleaning performance for standard maintenance needs. While lacking specialized features like descaling or enzymatic action, they effectively remove detergent residue and eliminate odors for regular washing machine maintenance.

I tested this cleaner in a moderately used washing machine without severe buildup. The tablets performed adequately for monthly maintenance, keeping odors at bay and preventing residue accumulation.

Budget-Friendly Effectiveness

While not as feature-rich as premium options, these tablets deliver reliable cleaning for standard maintenance needs. The extremely low cost per use makes regular washer maintenance accessible to any budget.

Who Should Buy?

Budget-conscious shoppers who want reliable basic cleaning without specialty features will find excellent value here. Perfect for standard maintenance on machines without serious odor or buildup issues.

Who Should Avoid?

Look elsewhere if you have severe odor problems, hard water issues, or need specialized cleaning features beyond basic maintenance.

Why Your Washing Machine Needs Regular Cleaning

A washing machine cleaner is a specialized cleaning product designed to remove odor-causing residue, mold, mildew, and bacteria buildup from washing machine drums, gaskets, dispensers, and internal components that regular washing cycles miss.

Most people assume their washing machine stays clean because it uses soap and hot water regularly. After seeing what accumulates inside washers that are never cleaned, I can tell you this assumption is dead wrong.

The problem starts with how we use our machines today. Modern detergents are concentrated, and many of us use too much. Cold water washes are common for energy savings, but they do not dissolve residues as effectively as hot water. High-efficiency machines use less water, leaving more residue behind.

This combination creates biofilm: a slimy layer of bacteria that produces that distinctive musty odor. Once established, this biofilm transfers to your clothes, making them smell musty even when freshly washed.

Front-load washers are particularly susceptible due to their rubber door gaskets, which trap moisture and debris. Top-load machines can develop problems around the agitator and underneath the drum where water pools.

Signs Your Washer Needs Cleaning

• Musty odor: Clothes smell worse after washing than before, or have a distinctive sour smell
• Visible mold: Black or dark spots on the door gasket (especially front loaders)
• Residue on clothes: Small specks or film left on freshly washed laundry
• Sour drain smell: Foul odor when machine drains or when door is opened
• Reduced cleaning performance: Clothes do not get as clean as they used to

How to Choose the Best Washing Machine Cleaner in 2026?

Selecting the right washer cleaner depends on your specific situation, machine type, and cleaning needs. Based on my testing experience, here are the key factors to consider.

Solving for Persistent Odors: Look for Time-Release Tablets

For ongoing odor problems that do not go away with standard cleaning, time-release tablets like Affresh provide the most thorough cleaning. The slow-dissolving formula continues working throughout the entire wash cycle, reaching areas where quick-dissolving powders cannot penetrate.

I found tablets particularly effective for front-load washers where the door gasket and drain hose are problematic areas. The tablet sits in the drum and slowly releases cleaning agents, allowing them to reach all internal components.

Solving for Hard Water: Look for Descaling Formulas

Hard water leaves mineral deposits that regular cleaners do not address. If you live in an area with hard water (you likely know if you do), a descaling formula like the 24-pack tablets we reviewed can make a significant difference.

Mineral scale builds up in the same areas as organic residue, compounding the problem. A descaler removes these mineral deposits, allowing your machine to run more efficiently and preventing scale-related odors.

Solving for Pet-Related Issues: Look for Enzymatic Cleaners

Pet hair, dander, and the occasional accident create unique challenges in washing machines. Enzymatic cleaners like ACTIVE break down organic matter at the molecular level, digesting the source of odors rather than just masking them.

For pet owners dealing with persistent biological odors or accidents washed in laundry, an enzymatic formula can be the difference between temporary relief and permanent solutions.

Solving for Budget Concerns: Look for Bulk Tablet Packs

The most economical options are bulk tablet packs. The 24-tablet options we reviewed cost as little as $0.42 per use compared to $2-3 for premium brands. For standard maintenance without severe issues, these provide excellent value.

Tablets offer additional savings through reduced waste and mess compared to powders. No spilled powder, no measuring, and consistent dosing every time.

Front-Load vs Top-Load Considerations

Feature	Front-Load Washer	Top-Load Washer
Problem Areas	Door gasket, drain hose	Agitator, under drum
Cleaning Frequency	Monthly recommended	Every 1-2 months
Cleaner Type	Tablets work best	Liquids or tablets
Additional Steps	Wipe gasket after use	Leave lid open between loads

Septic System Safety

If your home uses a septic system, you need a septic-safe formula. All the products we reviewed are septic-safe, but it is always worth confirming before purchasing. Harsh chemicals can disrupt the bacterial balance in your septic tank, leading to expensive problems.

Step-by-Step: How to Deep Clean Your Washing Machine

Deep cleaning your washing machine is a straightforward process that takes about an hour. Follow these steps for the best results based on my testing experience.

1. Remove visible debris: Wipe out the drum and remove any items left behind. For front loaders, pull back the door gasket and clean any mold or residue with a damp cloth.
2. Clean the dispenser drawer: Remove the detergent and fabric softener dispensers. Soak in hot water, scrub with a brush to remove buildup, and rinse thoroughly.
3. Add cleaning product: Place tablet directly in the drum (not the dispenser) or add powder according to package directions. Do not add laundry.
4. Run hottest cycle: Select the hottest water setting and the longest cycle. Many machines have a “Clean Washer” or “Tub Clean” cycle, use this if available.
5. Wipe down afterward: Once complete, wipe the drum, door, and gasket with a dry cloth. Leave the door or lid open to air dry completely.
6. Repeat if needed: For heavily soiled machines, repeat the process. I found two treatments a week apart work best for neglected machines.

Maintenance Schedule

Based on my experience and manufacturer recommendations, follow this schedule for optimal results:

• Monthly: Use a cleaning tablet for standard maintenance
• Quarterly: Deep clean dispenser drawers and gaskets
• As needed: Additional treatments if odors return or visible mold appears

Frequently Asked Questions

Final Recommendations

After six weeks of testing eight different products across multiple washer types, the results are clear. Affresh remains the top choice for its proven effectiveness and manufacturer backing, but the right cleaner depends on your specific situation.

For most households, Affresh tablets used monthly will keep your washer fresh and odor-free. Budget shoppers can save significantly with bulk tablet options without sacrificing much effectiveness. Pet owners and those with hard water should choose specialized formulas for their specific challenges.

Consistency matters more than which product you choose. Set a monthly reminder, use the product correctly, and your washing machine will stay clean and your laundry will smell fresh every time.
