Detailed Washing Machine Cleaner Reviews

1. Affresh Washing Machine Cleaner – Most Popular Choice

Affresh dominates the washing machine cleaner market for good reason – it’s the only cleaner officially recommended by Whirlpool, Maytag, and Amana, and after testing it against 11 competitors, I understand why.

The time-release tablets use a specialized formula that penetrates deep into hidden areas including the pump, valve, tub, drum, agitator, filter, and hoses where regular detergent can’t reach.

During my three-cycle test on a heavily soiled machine, Affresh removed years of accumulated grime and completely eliminated the musty odor that had persisted for months.

At $11.98 for six tablets, you’re paying about $2 per cleaning cycle, which is reasonable considering professional cleaning services charge $150-300 for severe buildup issues.

The EPA Safer Choice certification means it’s septic-safe, and the tablets work effectively in both standard and HE machines regardless of water temperature.

What Users Love: The No.1 selling status is backed by 272,781 reviews praising its effectiveness, ease of use, and noticeable results after just one cycle.

Common Concerns: Some users report needing multiple treatments for neglected machines, and tablets occasionally arrive broken due to shipping.

2. OxiClean Washing Machine Cleaner – Best Odor Eliminator

OxiClean’s washing machine cleaner combines their signature stain-fighting power with specialized Odor Blasters, creating a formula that tackles even the most persistent smells.

The pre-measured pouches eliminate guesswork – just tear one open, pour it into your empty washer drum, and run a hot water cycle for maximum effectiveness.

What sets this cleaner apart is its dual-action formula that both removes existing odor-causing residues and leaves a fresh, clean scent that lasts for weeks.

During testing, OxiClean showed exceptional performance on machines with pet hair and dander buildup, dissolving organic matter that tablet cleaners sometimes miss.

At $7.48 for four pouches, the cost per cleaning is just $1.87, making it 17% cheaper per use than Affresh while delivering comparable results.

What Users Love: Over 52,000 reviewers appreciate the convenient pouches, powerful cleaning action, and the fresh scent that doesn’t overwhelm.

Common Concerns: The fragrance can be too strong for sensitive users, and the powder format may create dust when pouring.

3. True Fresh Washing Machine Cleaner – Best Value Pack

True Fresh delivers exceptional value with 25 individually sealed tablets that provide over a year’s worth of monthly cleaning for just $18.95.

Each tablet breaks down into a powerful scrubbing powder that penetrates buildup in ways that surprised me during testing – particularly effective on hard water deposits.

The individual sealing is a game-changer for storage, keeping each tablet dry and potent even in humid laundry rooms where bulk tablets often deteriorate.

Compatible with all major brands including LG, Samsung, Whirlpool, and GE, these tablets work in both front-loaders and top-loaders regardless of age or efficiency rating.

At just $0.76 per cleaning cycle, True Fresh costs 62% less per use than Affresh while maintaining professional-grade cleaning power.

What Users Love: 24,043 reviewers praise the value proposition, long-lasting supply, and the fact that tablets stay fresh in individual packaging.

Common Concerns: The larger tablet size takes slightly longer to dissolve, and some users prefer more established brand names.

4. Tide Washing Machine Cleaner – Fastest Dissolving

Tide’s washing machine cleaner leverages their laundry expertise with a powder formula that dissolves 20% faster than tablet competitors, starting the cleaning action immediately.

The combination of Oxi and TAED (Tetraacetylethylenediamine) creates a powerful oxidizing reaction that’s particularly effective in hard water conditions where other cleaners struggle.

Each individually packaged powder packet provides precise dosing, and the included calendar helps maintain a regular cleaning schedule – something I found surprisingly helpful.

Testing showed exceptional results on detergent buildup and soap scum, with visible foam action that indicates active cleaning throughout the entire cycle.

At $21.99 for 10 packets, you’re paying a premium at $2.20 per use, but the faster action and hard water performance justify the cost for many users.

What Users Love: 25,380 reviewers highlight the rapid cleaning action, fresh scent, and effectiveness in areas with mineral-heavy water.

Common Concerns: The premium pricing and powder format that can be messier than tablets are the main drawbacks.

5. ACTIVE Washing Machine and Dishwasher Bundle – Best Bundle Deal

ACTIVE’s bundle provides 48 tablets split between washing machine and dishwasher cleaning, offering the best per-unit value I’ve found at just $0.69 per cleaning cycle.

The enzyme and oxygen-focused formula tackles multiple types of buildup including hard water deposits, lime scale, grease, and organic matter with impressive efficiency.

During my month-long test, using these tablets on a regular schedule completely transformed both appliances, eliminating odors and improving cleaning performance noticeably.

The deep descaling action is particularly effective on mineral buildup, which is crucial for the 85% of US homes dealing with hard water issues.

While the $32.95 upfront cost seems high, you’re getting a full year’s supply for two appliances, making this the most economical long-term option.

What Users Love: An impressive 138,648 reviewers appreciate the value, convenience of having both cleaners, and the noticeable improvement in appliance performance.

Common Concerns: Some users don’t need dishwasher cleaner, and the large quantity requires adequate storage space.

Bastion offers the most budget-friendly option at just $9.99 for 24 tablets, delivering a full year of bi-monthly cleaning at an unbeatable $0.42 per use.

Despite the low price, these tablets pack surprising cleaning power, effectively eliminating dirt, grime, and limescale in my test machines.

The biodegradable formula appeals to eco-conscious users, and the septic-safe certification means no worries about damaging your home’s wastewater system.

While the tablets are smaller than competitors, they still deliver results – though heavily soiled machines may benefit from using two tablets initially.

This cleaner proves that effective washing machine maintenance doesn’t have to break the bank, especially for regular preventive cleaning.

What Users Love: 3,112 reviewers praise the exceptional value, eco-friendly formula, and effectiveness despite the budget price point.

Common Concerns: Smaller tablet size may require doubling up for neglected machines, and brand recognition is limited.

7. ACTIVE Mold Stain Remover Gel – Best for Mold & Gaskets

ACTIVE’s gel cleaner addresses the number one complaint from front-loader owners – black mold and mildew on rubber door gaskets that tablets can’t reach.

The thick gel consistency clings to vertical surfaces and gasket folds, allowing the active ingredients to work for minutes rather than seconds.

In my testing, this gel removed stubborn black spots that had resisted multiple cleaning cycles with regular tablets, showing visible results within 15 minutes.

The 7-ounce bottle provides enough product for multiple deep cleaning sessions, and it also works on bathroom grout and shower seals.

At $15.26, it’s a specialized tool rather than a regular cleaner, but for gasket mold issues, it’s the most effective solution I’ve tested.

What Users Love: 13,334 reviewers celebrate finally finding something that removes stubborn gasket stains and the versatility for bathroom use.

Common Concerns: The bleaching action requires careful application, and protective equipment is essential during use.

8. iO CLEAN Washing Machine Cleaner – Best Effervescent Power

iO CLEAN’s effervescent tablets create an impressive fizzing action that visually demonstrates the cleaning process, providing confidence that the product is working.

The high-efficiency formula specifically targets detergent buildup and odors, with the effervescent action helping to lift and remove stubborn deposits.

At just $0.32 per tablet, this is the absolute lowest cost per cleaning cycle I found, making it ideal for frequent maintenance cleaning.

Testing showed excellent results on regular maintenance but slightly less effectiveness on heavy buildup compared to premium brands.

The individual packaging keeps each tablet fresh and dry, though it does create more waste than bulk packaging options.

What Users Love: 813 reviewers appreciate the visual cleaning action, ultra-low price point, and convenience of individual wrapping.

Common Concerns: Some users report needing multiple tablets for tough jobs, and the individual packaging creates environmental concerns.

9. Green Gobbler Washing Machine Cleaner – Best Eco-Friendly Option

Green Gobbler brings their drain-cleaning expertise to washing machines with a natural enzyme formula that’s tough on buildup but gentle on the environment.

The unique pipe clean technology doesn’t just clean the drum – it actively breaks down buildup in drain pipes, preventing clogs before they start.

Testing revealed exceptional performance on pet hair and organic matter, with the enzymes continuing to work even after the cleaning cycle ends.

The 28-tablet supply provides excellent value, and the 30-day money-back guarantee shows the company’s confidence in their formula.

At $15.26 for 28 tablets, you’re paying $0.55 per use for an eco-friendly solution that outperforms many chemical-based competitors.

What Users Love: 730 reviewers highlight the natural formula, effectiveness on pet-related issues, and the added benefit of pipe cleaning.

Common Concerns: As a newer product, long-term effectiveness data is limited, and the price is higher than basic options.

10. Seventh Generation Washing Machine Cleaner – Best Chemical-Free

Seventh Generation’s cleaner stands out as the most environmentally responsible option, with 92% USDA Certified Biobased content and EPA Safer Choice certification.

The oxy power formula effectively targets odor-causing residue without synthetic fragrances, dyes, or harsh chemicals that can trigger sensitivities.

During testing, this cleaner performed admirably on light to moderate buildup, though it required longer cycle times for heavily soiled machines.

The powder format dissolves quickly and completely, leaving no residue that could transfer to clothing in subsequent wash cycles.

At $12.99 for six packs, you’re paying a premium at $2.17 per use for the peace of mind that comes with truly clean ingredients.

What Users Love: 130 reviewers value the chemical-free formula, lack of artificial fragrances, and the company’s environmental commitment.

11. Uproot Clean Washing Machine Cleaner Ultra – Best for Pet Owners

Uproot Clean specifically engineered this cleaner for pet owners, with a 40% stronger formula that tackles the unique challenges of pet hair and dander.

The addition of Tea Polyphenols provides exceptional odor elimination, while active enzymes actually dissolve pet hair to prevent drain clogs.

My testing in a household with two dogs showed remarkable results – the cleaner removed embedded fur from drum holes and eliminated that persistent “wet dog” smell.

The ultra-concentrated tablets are designed for households with multiple or large pets where standard cleaners often fall short.

At $29.99 for 24 tablets, you’re investing $1.25 per cleaning for specialized pet-focused cleaning power that extends your machine’s life.

What Users Love: 4,307 pet-owning reviewers rave about finally finding a solution for pet-related washing machine issues and the hair-dissolving action.

Common Concerns: The premium price may not be justified for non-pet households, and some persistent odors still require multiple treatments.

12. Glisten Washing Machine Cleaner – Best Liquid Formula

Glisten’s liquid formula offers unique advantages over tablets and powders, flowing into areas that solid cleaners might miss during the dissolution process.

The liquid can be used during a regular wash cycle with clothes for maintenance cleaning, though empty cycles are recommended for deep cleaning.

What impressed me most was its versatility – you can apply it directly to door seals and detergent drawers for targeted spot cleaning.

The two-bottle pack provides multiple applications, with each 12-ounce bottle sufficient for 3-4 cleaning cycles depending on soil level.

At approximately $0.75 per use, Glisten offers good value for a liquid cleaner, especially considering the performance guarantee.

What Users Love: 6,016 reviewers appreciate the liquid’s ability to reach all areas, versatility for spot cleaning, and the satisfaction guarantee.

Common Concerns: Liquid can be messier than tablets, and severely neglected machines may need multiple treatments.

How to Choose the Best Washing Machine Cleaner

Selecting the right washing machine cleaner depends on several factors including your water quality, machine type, and specific cleaning needs.

Understanding Different Cleaner Types

Washing machine cleaners come in three main formats: tablets, powders, and liquids, each with distinct advantages.

Tablets offer convenience and precise dosing but may not dissolve completely in cold water or short cycles.

Powder cleaners dissolve faster and work better in hard water, though they can be messy and require careful measurement.

Liquid cleaners reach all areas immediately but cost more per use and can spill during storage.

Frequency and Maintenance Schedule

The cleaning frequency depends on usage patterns – monthly cleaning prevents 90% of odor issues according to appliance technicians.

Front-load washers require cleaning every 2 weeks due to their sealed design that traps moisture and promotes mold growth.

Top-load machines can go 4-6 weeks between cleanings, though pet owners should maintain a bi-weekly schedule regardless of machine type.

Cost Analysis and Value Comparison

Professional washing machine cleaning services charge $150-300, making regular DIY maintenance extremely cost-effective.

Budget cleaners like Bastion cost $0.42 per use, while premium options like Affresh run $2.00 – both beat professional service costs.

Consider that neglecting cleaning for 6+ months results in 80% odor development and potential repair costs exceeding $500.

Troubleshooting Persistent Problems

If odors persist after cleaning, the issue likely involves the rubber door gasket (front-loaders) or the drain pump filter.

Black mold on gaskets requires targeted treatment with gel cleaners like ACTIVE Mold Stain Remover rather than standard tablets.

Multiple consecutive cleaning cycles may be necessary for machines neglected for over six months – expect 3-4 treatments initially.

Frequently Asked Questions

Final Recommendations

After three months of testing 12 washing machine cleaners and analyzing over 500,000 customer reviews, clear winners emerged for different needs.

Budget-conscious buyers should choose Bastion’s 24-pack at just $0.42 per use, while pet owners need Uproot Clean’s specialized formula.
