Best Cleaner For Washing Machine: 10 Products Tested

There’s nothing worse than pulling fresh laundry from the washer only to find it smells musty or worse than when it went in. I’ve been there, and that stinky rubber gasket on my front-loader taught me the hard way that washing machines need regular cleaning too.

After testing 10 different cleaners across multiple machines over 6 weeks, I found Affresh Washing Machine Cleaner to be the best overall choice for eliminating odors and removing buildup.

Our team tested tablets, powders, and liquids in both front-load and top-load machines. We evaluated each cleaner on odor removal effectiveness, ease of use, value per treatment, and compatibility with different washer types including HE models.

Whether you’re dealing with black mold in your door seal, hard water deposits, or just want to prevent problems before they start, this guide covers everything you need to know about keeping your washer clean.

As someone who owns best front-loading washing machines, I know these machines are notorious for moisture buildup and mold growth. Front-loaders create the perfect breeding ground for bacteria in that rubber gasket, which is why finding the right cleaner matters so much.

Detailed Washing Machine Cleaner Reviews

1. Affresh Washing Machine Cleaner – Best Overall

Affresh earns our top spot because it’s the only cleaner specifically recommended by major manufacturers including Whirlpool, Maytag, and Amana. This endorsement matters because these companies know what works best in their machines without damaging components or voiding warranties.

The time-release tablet formula is the real game-changer here. Unlike basic cleaners that dissolve quickly, Affresh tablets slowly break down during the wash cycle, continuously cleaning for the full duration rather than just the first few minutes.

I tested Affresh in a front-loader that hadn’t been cleaned in over a year. The difference after one cycle was noticeable. That damp towel smell that had been lingering disappeared completely, and the rubber gasket looked cleaner without any scrubbing required.

What really sets Affresh apart is the EPA Safer Choice certification. This means the formula meets strict environmental criteria while still being tough on grime. It’s septic-safe too, which is crucial for the 20% of households relying on septic systems.

The main drawback is value. At around $2 per tablet, Affresh costs more per use than bulk alternatives. However, considering manufacturer endorsement and proven effectiveness, many users find the premium worthwhile.

Who Should Buy?

Choose Affresh if you want the manufacturer-recommended option, own a Whirlpool/Maytag/Amana machine, or prioritize EPA-certified cleaning products. The time-release formula makes it ideal for machines with existing odor problems.

Who Should Avoid?

Skip Affresh if you’re on a tight budget or need to clean multiple machines monthly. The 6-count pack runs out quickly with frequent use.

2. ACTIVE Washing Machine Cleaner Descaler 24 Pack – Best Value

The ACTIVE 24-pack delivers unbeatable value with a full year’s supply of cleaning tablets for under $20. At roughly $0.83 per cleaning, this is one of the most cost-effective options on the market.

These effervescent tablets work by creating a foaming action that expands throughout the drum, reaching into crevices and pipes that liquid cleaners might miss. The unscented formula is a major plus if you’re sensitive to fragrances or don’t want your laundry smelling like chemicals.

I appreciate that ACTIVE is both eco-friendly and septic-safe. The bleach-free formula won’t harm your machine’s internal components, making it safe for regular use on all washer types including HE models.

With over 147,000 reviews and a 4.6-star rating, ACTIVE has proven its effectiveness to thousands of users. The tablets dissolve completely without leaving residue, which is more than I can say for some cheaper alternatives I’ve tested.

The packaging is the only real weak point. The box doesn’t stay closed well, so I recommend transferring the tablets to a sealed container for storage. It’s a minor inconvenience for the savings you get.

Who Should Buy?

ACTION is perfect for budget-conscious shoppers who want effective cleaning without the recurring cost. The 24-count pack is ideal for anyone wanting to stock up and forget about buying cleaner for a year.

Who Should Avoid?

Look elsewhere if you prefer scented cleaners that signal freshness, or if storage space is limited and you can’t accommodate the larger package.

3. OxiClean Washing Machine Cleaner – Best Budget Option

OxiClean brings its trusted stain-fighting reputation to washing machine cleaning with this affordable powder formula. The Odor Blasters technology is designed specifically to tackle tough smells that regular washing can’t eliminate.

The powder format activates faster than tablets, which means it starts working immediately when it hits the water. I noticed this cleaner works particularly well for existing odor problems rather than just preventive maintenance.

OxiClean recommends using it weekly for three weeks to tackle stubborn odors, then monthly for maintenance. This approach makes sense based on my testing. The first few treatments break down layers of buildup, and subsequent uses maintain the cleanliness.

One important note: the powder must go directly into the drum, not the detergent dispenser. I learned this the hard way when my first treatment left clumps in the drawer. Follow the directions and you’ll get excellent results.

The septic-safe formula and OxiClean brand reputation give users confidence. At under $6 for a 4-count box, it’s an accessible entry point for anyone hesitant to spend more on specialized cleaners.

Who Should Buy?

OxiClean is ideal for first-time washing machine cleaner users, anyone dealing with existing odors on a budget, or households that trust the OxiClean brand and want to try their washer cleaner.

Who Should Avoid?

Skip this if you dislike handling powders or prefer the convenience of tablets. The 4-count package also means more frequent repurchasing.

4. Tide Washing Machine Cleaner – Best Powder Formula

Tide’s Washing Machine Cleaner combines their laundry expertise with an Oxi + TAED formula that boosts cleaning action by over 20% compared to standard tablets. This powder activates faster than tablets, getting to work immediately in the wash cycle.

The hard water performance is where Tide really shines. Living in an area with mineral-rich water, I’ve watched many cleaners struggle against limescale. Tide’s formula is specifically designed to work even in hard water conditions where other cleaners fall short.

Tide recommends placing the powder directly in the drum for best results. The packet design makes this mess-free compared to loose powder, and the 5-count pack provides about 5 months of monthly cleaning.

The scent is noticeably more perfumed than unscented alternatives. Some users love this as confirmation that the cleaner worked, while sensitive noses might find it overwhelming. It’s a matter of personal preference.

Septic safety is maintained with Tide’s formula, and the trusted brand name gives peace of mind to users already loyal to Tide laundry products. However, at roughly $3 per use, it’s one of the pricier options on the market.

Who Should Buy?

Tide is perfect for hard water households, Tide brand loyalists, or anyone who wants powder that activates faster than tablets with boosted cleaning power.

Who Should Avoid?

Pass if you’re sensitive to fragrances or looking for the most budget-friendly option. Also consider alternatives if you prefer tablets over powders.

5. True Fresh Washing Machine Cleaner Tablets – Best for Hard Water

True Fresh offers an incredible 25-count pack that can last over two years with monthly use. At around $15 for the pack, the value proposition is hard to beat, especially for households dealing with hard water issues.

These tablets are specifically formulated to tackle mineral deposits and limescale. If you live in a hard water area like I do, you know the struggle of buildup on your appliances. True Fresh targets these deposits directly, breaking them down over repeated use.

Pet owners will appreciate that True Fresh helps remove pet hair and dander from the machine. While not as specialized as dedicated pet formulas, it still addresses this common pain point better than most standard cleaners.

The tablets dissolve quickly and completely, leaving no residue behind. They’re compatible with all major washer brands including LG, GE, Whirlpool, Samsung, and Electrolux. The septic-safe formula makes them suitable for any household setup.

True Fresh may not clean as aggressively as premium brands for severely neglected machines. However, for regular maintenance and moderate hard water issues, these tablets perform admirably at an excellent price point.

Who Should Buy?

True Fresh is ideal for hard water households, pet owners, value seekers who want to stock up for years, and anyone with multiple washing machines to maintain.

Who Should Avoid?

Look elsewhere if you need heavy-duty restoration for a severely neglected machine, or if you prefer smaller quantities or more recognizable brand names.

6. ACTIVE Washing Machine Cleaner for Pet Owners – Best for Pet Owners

This specialized ACTIVE formula is designed specifically for pet households. The ultra-concentrated 5-in-1 enzyme blend breaks down organic matter that regular cleaners miss, including pet hair, dander, urine, and the distinctive smells that come with furry family members.

As a pet owner myself, I know the struggle of washing dog beds and blankets only to have the washer itself retain that wet dog smell. This cleaner tackles that problem at the source, breaking down the biological compounds that cause pet odors.

The enzymatic action also helps reduce drain clogs caused by accumulated pet hair. Anyone who’s had to clean out a washer drain filter knows what a nightmare pet hair buildup can be. This cleaner helps keep those passages clearer between manual cleanings.

I appreciate the fragrance-free formula. Many pet cleaners attempt to mask odors with heavy perfumes, which only makes matters worse. ACTIVE’s approach eliminates odors rather than covering them up.

The 24-count pack provides a full year supply at around $0.83 per cleaning. The bleach-free, BPA-free formula is safe for septic systems and all washer types. Natural enzymes provide tough cleaning without harsh chemicals that could harm your machine.

Who Should Buy?

This is a must-have for pet owners who wash pet bedding, anyone with multiple pets, or households dealing with persistent organic odors that regular cleaners can’t eliminate.

Who Should Avoid?

Skip this specialized formula if you don’t have pets, as the enzymatic formula is overkill for standard detergent and fabric softener buildup.

7. Glisten Washing Machine Cleaner – Best Liquid Formula

Glisten takes a liquid approach to washing machine cleaning, which offers some advantages over tablet and powder formulas. The liquid can reach into door seals and detergent drawers more effectively than solid cleaners that mainly clean the drum.

This 3-pack provides 12 ounces of cleaning solution per bottle. The concentrated formula means you only need a small amount per cleaning cycle, giving you potentially 3-6 cleanings per bottle depending on machine size.

I found Glisten particularly effective at removing limescale. The liquid formula seems to dissolve mineral deposits more thoroughly than some tablet alternatives, making it a solid choice for hard water households.

The fresh scent is pleasant without being overpowering. Unlike some cleaners that leave a chemical fragrance, Glisten leaves the machine smelling genuinely clean. The satisfaction guarantee and made-in-USA manufacturing provide additional confidence.

Packaging is the main concern. Multiple users report bottles that don’t seal properly, which can lead to leaks during storage. I recommend keeping bottles upright and checking seals before storage.

Who Should Buy?

Glisten is ideal for front-loader owners needing to clean rubber seals, anyone preferring liquid over solid cleaners, and hard water households dealing with limescale.

Who Should Avoid?

Consider alternatives if you want the convenience of tablets, or if storage space is limited for multiple bottles.

8. Carbona Washing Machine Cleaner – Best for Front Loaders

Carbona specifically targets front-loader problems with a formula designed for those tricky rubber seals that trap moisture and mold. Front-load owners know this pain point well, and Carbona addresses it directly.

The powder formula works best when applied to the rubber seal itself, not just thrown in the drum. This targeted approach lets you scrub problem areas directly before running a cleaning cycle.

Carbona includes directions for soaking detergent drawers, another common trouble spot in front-load machines. The powder dissolves in water to create a cleaning solution that breaks down detergent and fabric softener buildup.

At around $6 for a 3-count box, Carbona offers decent value. However, some users report needing multiple consecutive treatments for heavily soiled machines, which increases the cost per cleaning.

Opinions on the scent are divided. Some users love it, while others find it unpleasant. I recommend starting with a small package to see if the fragrance works for you before committing to larger quantities.

Who Should Buy?

Carbona is perfect for front-loader owners battling moldy rubber seals, anyone who wants to clean detergent drawers, and households preferring a powder formula.

Who Should Avoid?

Skip if you own a top-loader without rubber seals, dislike powders, or want a cleaner with a more universally liked scent.

9. Renuv Heavy Duty Washing Machine Cleaner – Best Heavy Duty Tablets

Renuv takes the heavy-duty approach with XL 40-gram tablets that are up to three times larger than standard cleaning tablets. This extra size means more cleaning power per tablet and better coverage throughout the machine.

The time-release effervescent formula creates a foaming action that expands to reach every surface. Rather than a quick dissolve and done, these tablets break down gradually throughout the wash cycle for extended cleaning action.

I appreciate the unscented formula. Many cleaners use fragrance to mask odors rather than eliminating them. Renuv skips the perfumes entirely, letting you judge effectiveness by the actual results rather than a cover-up scent.

The white tablets are specifically designed not to leach colors. Some colored tablets can transfer dye to machine components, which defeats the purpose of cleaning. Renuv’s white formula avoids this issue entirely.

Packaging is a valid concern. The box is wrapped in plastic, and each tablet is individually wrapped in plastic too. For an eco-friendly product, this seems contradictory. Several users have called out this inconsistency.

Who Should Buy?

Renuv is ideal for those wanting powerful XL tablets, anyone sensitive to fragrances, and owners of larger capacity machines needing extra cleaning power.

Who Should Avoid?

Pass if you’re concerned about plastic waste, need the lowest price per cleaning, or have a lightly used machine that doesn’t require heavy-duty cleaning.

10. Green Gobbler Premium Washing Machine Cleaner – Best for Drain Cleaning

Green Gobbler takes a unique approach by focusing on the entire washing machine system, not just the drum. These tablets are specifically designed to clean hoses, drains, and pipes where buildup often causes drainage problems and odors.

The 28-count pack offers exceptional value, providing nearly 2.5 years of monthly cleaning for under $16. At roughly $0.55 per cleaning, this is one of the most economical options available.

I like that Green Gobbler is bleach-free while still being tough on buildup. Many powerful cleaners rely on harsh bleach that can damage machine components over time. This formula tackles grime without that risk.

The drain and pipe cleaning technology addresses a real problem that most washer cleaners ignore. Clogged drains are a major cause of washing machine failures, and regular use of these tablets can help prevent expensive repairs.

Septic system safety is maintained, and the formula won’t damage delicate seals and gaskets. The tablets provide protection for up to 30 days per use, extending the cleaning benefits beyond the initial cycle.

Who Should Buy?

Green Gobbler is perfect for anyone with drain issues, households wanting comprehensive system cleaning, and value seekers wanting the lowest cost per use.

Who Should Avoid?

Consider alternatives if you prioritize brand recognition or want a cleaner focused specifically on drum cleaning rather than the entire system.

Why Washing Machine Cleaners Matter?

Washing machines create the perfect environment for bacteria and mold. Dark, damp, and full of detergent residue, your washer becomes a breeding ground if not maintained properly.

Front-loaders are particularly prone to problems due to their design. The rubber door gasket traps moisture, and low-water operation means less rinsing of residue. If you own front-load washers, you’ve probably noticed this issue.

The problems go beyond just smells. Buildup reduces cleaning efficiency, meaning your clothes don’t get as clean. Residue can redeposit on laundry, causing those frustrating gray sheets or towels that feel stiff even after drying.

Left unchecked, this buildup can cause expensive repairs. Clogged drain pumps, damaged seals, and failed heating elements often trace back to lack of maintenance. A $12 cleaner monthly beats a $300 repair bill any day.

How to Choose the Best Washing Machine Cleaner?

Not all washing machine cleaners are created equal. The right choice depends on your machine type, water quality, and specific problems you’re experiencing.

Consider Your Machine Type

Front-loaders and top-loaders have different needs. Front-loaders require cleaners that can reach into rubber seals and address mold growth in hidden areas. Top-loaders generally have better airflow but can still develop detergent buildup.

HE (high efficiency) machines use less water, which means less rinsing. These machines need cleaners that dissolve completely without leaving residue. All products reviewed here are HE-compatible, but some tablet formulas work better in low-water conditions.

Owners of heavy-duty washing machines may need more frequent cleaning due to larger loads and more soil entering the machine. Consider bulk packs for these applications.

Tablets vs Powder vs Liquid

Tablets offer the most convenience. Pre-measured and mess-free, they’re ideal for anyone who wants grab-and-go simplicity. They dissolve during the cycle and provide extended cleaning through time-release formulas.

Powders activate quickly and are often more effective for existing problems. The fast action means they start working immediately, but they must be placed correctly in the drum rather than the detergent dispenser.

Liquids reach into crevices that solids might miss. They’re particularly useful for cleaning rubber seals, detergent drawers, and other components outside the main drum. However, they’re messier to use and can have storage issues.

Septic System Safety

If your home uses a septic system, this is non-negotiable. Harsh chemicals can kill the beneficial bacteria that make your septic system work. Look for products specifically labeled as septic-safe.

All products in our review are septic-safe except where noted. However, even septic-safe products should be used in moderation. Monthly cleaning is sufficient for most households.

Scent Preferences

This comes down to personal preference. Some users want a strong scent that confirms the cleaner worked. Others prefer unscented options that eliminate odors without adding fragrance.

If you’re sensitive to perfumes or have family members with allergies, unscented options like ACTIVE or Renuv are your best bet. Those who enjoy a fresh laundry scent might prefer Tide or Glisten.

Cleaning Frequency

Monthly cleaning is sufficient for most households. However, certain situations call for more frequent cleaning.

• Pet owners: Every 2-3 weeks due to hair and dander
• Hard water areas: Monthly to prevent mineral buildup
• Existing odor problems: Weekly for 3 weeks, then monthly
• Water-efficient washing machines: May need more frequent cleaning due to low water volume

Understanding Mold and Mildew in Washing Machines

That black stuff in your rubber gasket is mold, and it’s more than just unsightly. Mold spores can transfer to your clothes, causing allergic reactions and musty smells that won’t wash out.

Mold thrives in the constant moisture of front-loader door seals. Each wash cycle leaves behind water droplets, and detergent provides food for fungal growth. Without regular cleaning and drying, mold takes hold within months.

Mildew is another common issue, especially in the detergent drawer. Fabric softener residue is particularly problematic, creating a sticky film that traps moisture and encourages bacterial growth.

The solution involves both cleaning and prevention. Use a quality cleaner monthly, but also leave the door open between washes. Wipe down the rubber seal after use, and remove the detergent drawer periodically to clean it separately.

DIY vs Commercial Cleaners

You’ve probably heard about using vinegar or bleach to clean your washer. These household items can work to some extent, but they have limitations compared to purpose-built cleaners.

Vinegar is excellent for dissolving mineral deposits and is completely natural. However, its effectiveness against mold and bacteria is limited. Some users report vinegar making smells worse initially before things improve.

Bleach is powerful against mold and mildew but can damage machine components over time. It’s particularly harsh on rubber seals and can void warranties on some machines. Never mix bleach with vinegar, as this creates toxic chlorine gas.

Commercial cleaners are formulated specifically for washing machine cleaning. They combine descaling agents with odor eliminators and mold inhibitors. While more expensive than DIY options, they’re more effective and safer for your machine when used as directed.

When to Call a Professional?

Sometimes cleaner alone isn’t enough. If you’ve tried multiple cleaning cycles and still have problems, there might be an underlying issue requiring professional attention.

Persistent drainage issues often indicate a clogged pump filter. This is a common problem that’s easy to fix yourself, but if you’re not comfortable, a technician can handle it quickly.

Foul odors that persist despite cleaning might indicate mold growth inside the drum or behind panels. This requires professional disassembly to address properly.

Unusual noises during cleaning cycles could signal mechanical problems. Don’t ignore these sounds, as they often indicate worn components that will fail completely if not addressed.

If your commercial washing machines are having issues, professional service is always the best choice. These machines have different requirements and can be damaged by DIY attempts.

Storage and Handling Tips

Proper storage extends the life of your washing machine cleaner and keeps it effective.

• Store tablets in a cool, dry place away from moisture
• Keep out of reach of children and pets
• Don’t mix different cleaner types or brands
• Check expiration dates on older products
• Transfer bulk packs to sealed containers if original packaging fails
