Detailed Washing Machine Cleaner Reviews

1. Bastion Washing Machine Cleaner – Best Budget Option

At just $5.95 for a 3-month supply, Bastion delivers impressive cleaning power that rivals products costing twice as much.

The eco-friendly tablets effectively eliminated the musty smell from my front-loader after just one cycle, though heavily soiled machines might need two tablets for the first cleaning.

Each tablet dissolves completely within 5 minutes, releasing powerful cleaning agents that tackle both odor-causing bacteria and mineral deposits.

The biodegradable formula works safely with septic systems, making it ideal for rural homes or anyone concerned about environmental impact.

After using Bastion monthly for 3 months, my washer drum stays noticeably fresher between cleanings compared to when I used DIY vinegar solutions.

What Users Love Most

Customers consistently praise the unbeatable price point and effectiveness, with 66% giving it 5 stars despite being a budget option.

2. OxiClean Washing Machine Cleaner – Best Deep Cleaning Power

OxiClean’s Odor Blasters formula tackles the toughest washing machine odors with pre-measured powder pouches that activate on contact with water.

During testing, this cleaner removed visible soap scum buildup that other products left behind, particularly effective on the rubber door seal of front-loaders.

The powder formula activates 20% faster than tablets according to the manufacturer, and I noticed vigorous foaming action within seconds of starting the cycle.

With over 52,000 reviews averaging 4.6 stars and 30,000+ units sold monthly, OxiClean has proven its effectiveness across thousands of households.

The only downside is the strong fragrance that some users find overwhelming, though it dissipates completely after running an empty rinse cycle.

For machines with severe odor issues or visible grime, OxiClean provides the deep cleaning power needed to restore freshness.

Professional Cleaning Performance

The septic-safe formula breaks down completely without harming plumbing systems, making it suitable for all home types.

3. Affresh Washing Machine Cleaner – Best Overall & Editor’s Choice

Affresh dominates the washing machine cleaner market as the #1 seller with over 272,000 reviews, and after extensive testing, I understand why.

Recommended by Whirlpool, Maytag, and Amana, these tablets use time-release technology to clean deep inside the pump, valve, tub, drum, and hoses.

The EPA Safer Choice certification means you’re getting powerful cleaning without harsh chemicals that could damage your washer’s components.

During our 3-month test period, monthly Affresh treatments kept our test washers odor-free longer than any other product we tried.

At $2 per cleaning cycle, it costs more than budget options but delivers consistent, professional-grade results that justify the premium.

The tablets work effectively in both standard and HE machines, dissolving completely without leaving residue or requiring extra rinse cycles.

Why Appliance Manufacturers Recommend Affresh

Major brands specifically engineer their cleaning cycles to work optimally with Affresh’s formula, ensuring maximum effectiveness.

4. Tide Washing Machine Cleaner – Best Powder Formula

Tide’s powder formula with Oxi and TAED technology activates 20% faster than tablets, delivering visible cleaning action within minutes.

The 5-month supply provides excellent value at $2.30 per cleaning, especially considering its superior performance in hard water conditions.

I tested this in a home with extremely hard water (18 grains per gallon) where other cleaners struggled, and Tide removed mineral deposits effectively.

The powder dissolves completely even in cold water, though Tide recommends using hot water for maximum cleaning power.

Over 25,000 customers rate it 4.6 stars, with 79% giving it perfect scores for odor elimination and ease of use.

The fresh scent is milder than OxiClean but still noticeable during cleaning, completely disappearing after the cycle completes.

Hard Water Solution

If you struggle with mineral buildup and other cleaners haven’t worked, Tide’s specialized formula tackles hard water challenges effectively.

5. Mighty Clean 24-Pack – Best Value Pack

At just $0.58 per cleaning cycle, Mighty Clean offers the lowest cost per use of any product we tested.

The 24-tablet pack provides a full year of monthly cleanings, eliminating the hassle of frequent reordering.

Despite being a newer brand with only 2,618 reviews, it maintains an impressive 4.5-star average with 73% perfect ratings.

Each tablet works universally with all washer types, including HE machines, front-loaders, and traditional top-loaders.

The tablets effectively removed moderate buildup and odors in our tests, though heavily soiled machines needed two tablets initially.

For budget-conscious households doing regular maintenance cleanings, this bulk pack offers unbeatable long-term value.

Smart Shopping Choice

Buying in bulk saves 70% compared to purchasing monthly supplies individually, making this perfect for large families or multiple washers.

6. Seventh Generation – Best Eco-Friendly

Seventh Generation delivers eco-conscious cleaning with 92% USDA Certified Biobased ingredients and zero fragrances or dyes.

The oxy-powered formula effectively lifts odor-causing residue without harsh chemicals, perfect for sensitive skin or allergies.

As a certified B Corp with Leaping Bunny certification, this product aligns with sustainable and cruelty-free values.

The mess-free packs dissolve completely in all water temperatures, though hot water enhances cleaning effectiveness.

While gentler than chemical-heavy alternatives, it still eliminated mild to moderate odors in our testing.

For eco-minded consumers willing to pay slightly more for environmental responsibility, Seventh Generation delivers peace of mind.

Environmental Impact

Each purchase supports sustainable manufacturing practices and reduces chemical runoff into water systems.

7. ACTIVE Washing Machine Cleaner – Best for Heavy-Duty Cleaning

With over 138,000 reviews and 90,000+ monthly sales, ACTIVE ranks #2 in washing machine cleaners for good reason.

The effervescent tablets create powerful foaming action that reaches every corner of your washer drum and components.

I watched through my front-loader’s window as the tablets created impressive bubbling action that lasted the entire cycle.

The deep scrubbing powder breaks down even stubborn grime that’s been building up for months or years.

At $0.83 per cleaning, it costs more than Mighty Clean but delivers noticeably stronger cleaning power for neglected machines.

The unscented formula leaves no fragrance behind, ideal for those sensitive to artificial scents.

Restoration Power

For washers that haven’t been cleaned in over 6 months, ACTIVE’s powerful formula can restore them to like-new condition.

8. Glisten Washer Magic – Best Liquid Formula

Glisten’s liquid formula penetrates and dissolves buildup that tablets might miss, especially in hard-to-reach areas.

The 4-bottle pack provides 4 months of cleaning at the highest price point of $6.73 per use.

Despite only 667 reviews, it maintains a strong 4.6-star rating with 77% perfect scores from satisfied users.

The liquid flows directly into pump mechanisms and hose connections where residue accumulates over time.

During testing, Glisten removed soap scum rings that had resisted tablet cleaners for months.

The fresh scent is pleasant but strong during cleaning, requiring good ventilation if you’re sensitive to fragrances.

When Liquid Works Better?

For older machines with significant buildup or complicated internal mechanisms, liquid formulas provide superior penetration.

How to Choose the Best Washing Machine Cleaner?

Selecting the right washing machine cleaner depends on your specific needs, washer type, and cleaning frequency.

Types of Washing Machine Cleaners Explained

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

Tablets offer the most convenience with pre-measured doses and no mess, making them perfect for regular maintenance.

Powder formulas activate faster and work better in hard water conditions but require careful measuring.

Liquid cleaners penetrate deep buildup most effectively but cost more and can be messy to pour.

Key Factors to Consider

Consider your water hardness level when choosing a cleaner – hard water areas need stronger formulas like Tide or OxiClean.

Budget-conscious buyers should calculate cost per use rather than package price – bulk packs offer 70% savings over time.

Check for septic system compatibility if you have one, though all products we tested are septic-safe.

Usage Frequency Guidelines

1. Monthly cleaning: Front-load washers and households doing 8+ loads weekly
2. Bi-monthly cleaning: Top-load washers with moderate use (4-7 loads weekly)
3. Quarterly cleaning: Lightly used machines (less than 4 loads weekly)
