A washing machine that smells musty, leaves a film on your clothes, or just looks grimy on the gasket isn’t broken — it’s neglected. The good news is that cleaning it does not take a service call or a chemistry degree. The trick is matching the right formula to your machine’s specific problem — hard-water scale, soap scum, or mildew odor.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
But choosing the right best cleaning washer means deciding between a budget 28-pack and a premium brand trusted by Whirlpool engineers — and the trade-offs matter more than you think.
Our Picks at a Glance
How To Choose The Best Cleaning Washer
The right formula depends on your machine type and your specific annoyance — odor, visible grime, hard-water scale, or residue on clothes. Knowing which format to reach for saves you from messing with the wrong product and being disappointed.
Tablet vs Liquid vs Powder
Tablets are the most popular because they are drop-in simple — no measuring, no pouring, no mess. They dissolve slowly and release cleaning agents over a full hot-water cycle. Liquids like the Glisten formula are better at reaching the drum’s hidden underside and the detergent drawer because they mix into the water immediately, which helps with deep limescale buildup. Powders, such as the Tide option, activate faster than tablets and can be ideal when you want a burst of cleaning action early in the cycle, especially for hard water.
Septic Safety and Eco-Credentials
Nearly every cleaner in this guide is septic-safe, but not all are EPA Safer Choice Certified or USDA Biobased. If you are on a septic system, look for the specific claim — most tablets state it clearly. If you are sensitive to fragrances, the Seventh Generation cleaner is explicitly fragrance-free, while Molly’s Suds and Plink rely on natural citrus oils rather than synthetic perfumes.
Annual Supply Economics
A 12-tablet pack used monthly lasts one year. Some brands, like Affresh and ACTIVE, bundle 24 or more tablets so you do not have to reorder. A larger pack sounds expensive upfront but saves you the hassle of restocking and often costs less per treatment than a 6-pack from a premium brand.

In-Depth Reviews
1. Plink Washing Machine and Dishwasher Cleaner, Lemon, 12 Tablets
Our pick — over 4.5★ from 750+ verified ratings; the strongest balance of quality and price.
One tablet cleans both the washer and the dishwasher — a rare dual-purpose trick.
Plink offers something no other product in this guide does: a single tablet that cleans both your washing machine and your dishwasher. The lemon-scented formula removes odor-causing residue from hidden parts without phosphates (chemicals harmful to water systems) or bleach. Owners describe it as “essential for maintaining a fresh sink” and easy to use — just drop one in and run a cycle. Cleaning performance gets 71 mentions and fragrance gets 51, both strongly positive.
The tablet is made in the USA and works with all plumbing systems. It is also septic friendly. The 12-tablet supply works out to about 12 weeks if you clean weekly. The versatility is the real hook here: one product covers two appliances, simplifying your cleaning cabinet. The package dimensions (8.9 x 5.63 x 2.52 inches) are noticeably larger than single-purpose competitors’ boxes, but that is the cost of the dual-action formula. If you buy this instead of separate cleaners for each machine, you save cabinet space.
Two-for-one: Cleans both the washing machine and the dishwasher, so you only need one product in the cabinet.
Light scent: Lemon fragrance that owners describe as refreshing, not chemical.
Reach for this if: you want one product to maintain two appliances and prefer a simple, no-measure tablet.
Think twice if: you need a dedicated deep-clean tablet for a heavily scaled washer — the dual-purpose formula is milder.
2. Affresh Washing Machine Cleaner, 12 Time Release Tablets
The crowd favorite that appliance engineers actually recommend for monthly maintenance.
Affresh holds the rare distinction of being the No. 1 washing machine cleaner tablet and the brand recommended by Whirlpool, Maytag, and Amana. Each time-release tablet is designed to deliver cleaning power throughout the entire wash cycle, targeting the pump, drum, filter, and hoses. Buyers report that a single tablet eliminates musty odors from front-load HE washers after just one cycle — no scrubbing, no second treatment needed.
The catch, and it is a small one, is the price. A 12-tablet supply (one full year) sits at the premium end of the market. Some owners also note a bit of white residue if the tablet does not fully dissolve, though that is a risk with any cleaner in hard water. The consensus is clear: Affresh works better at preventing odors than at removing heavy existing stains, making it a stellar maintenance choice rather than a rescue cleaner for a neglected machine.
The fragrance is pleasant without being overpowering, and the tablets are EPA Safer Choice Certified and septic safe. If your washer smells fine but you want to keep it that way, this is the tablet to set and forget.
What wins owners over
- Effectiveness gets over 7,200 positive mentions — owners call it essential for odor control
- Dissolves residue in unreachable areas like the pump and hoses
- Backed by Whirlpool, Maytag, and Amana engineers
- One tablet per month, no measuring, no mess
The trade-off
- More expensive per tablet than budget 24-packs
- A few owners see white residue in hard water areas
Reach for it if: you want a monthly maintenance routine that prevents smells before they start, and you want a brand trusted by the engineers who built your washer.
Look elsewhere if: you need a cheap per-treatment cost or must remove thick existing limescale — a liquid descaler like Glisten may be better for that first deep clean.
3. Tide Washing Machine Cleaner 52 Week Supply
The powder that activates faster than any tablet and comes with a full year of clean.
Tide takes a different approach with a powder packet that, according to the brand, activates 20% faster than tablets. The Oxi plus TAED (a bleach activator) formula is designed to boost cleaning action, and it works even in hard water that can dull other cleaners. Owners who tried multiple products before landing on this one report that odors from front-load machines vanish after a single treatment — a significant claim given how persistent those smells can be.
The 52-week supply means you get one packet per week for a full year in one package. That volume makes Tide a strong value play, especially compared to boutique brands that sell smaller counts at similar prices. The fresh linen scent gets consistent praise, though a few owners note it leaves a slight residue that wipes away easily with a microfiber cloth — hardly a dealbreaker for a product this effective.
Compared to the Affresh tablet, Tide’s powder dissolves faster and may be a better fit for hard water homes. It works in both front and top loaders, including HE washers.
Speed advantage: Activates faster than tablets, making it a stronger option for hard water.
Scent payoff: A fresh linen smell that owners describe as pleasant and not chemical — the fragrance gets 45 mentions as a positive.
Pick this for: fast-working cleaning in hard water, plus the convenience of a full year’s supply in one box.
skip it if: you prefer a fragrance-free formula or dislike wiping away minor residue after the cycle.
4. ACTIVE Washing Machine Cleaner Descaler 24 Pack
Two years of cleaning in one resealable bag, for a fraction of the premium price.
The ACTIVE 24-pack delivers the lowest per-treatment cost in this guide while still earning strong owner scores. These natural effervescent (fizzing) foaming tablets are bleach-free and septic safe, and they work in both HE front loaders and standard top loaders. The deep scrubbing action breaks down grime and hard water buildup without any brushing or wiping — just drop one in the drum, run a hot cycle, and let the bubbles do the work.
Reviewer counts are unusually high here: effectiveness gets 7,900 positive mentions, scent gets 4,500, and cleaning performance gets 4,400. Owners consistently describe their washers as “sparkling clean” and “like new” after a single use. The bulk 24-count package covers a full 12-month supply, which makes it a hands-off purchase for the forgetful owner. The downside is the residue question — about 891 mentions flag it as mixed, meaning a minority of owners see a white film after the cycle, though most find it easy to wipe away. Compared to the premium-priced Affresh at 12 tablets, you get 24 treatments versus 12 for less per tablet.
Bulk value: 24 tablets for roughly half the per-tablet cost of premium brands.
Residue note: A vocal minority sees white film; run a second rinse if your water is hard.
Go for this if: you want the most treatments for your money and do not mind a simple wipe-down afterward.
Think twice if: you are sensitive to residue and want a formula that leaves zero trace every time.
5. Molly’s Suds Washing Machine Cleaner, Citrus, 10 Tablets
A jumbo citrus tablet that uses enzymes, not bleach, to eat through months of grime.
Molly’s Suds stands apart with a formula powered by active enzymes (natural proteins that break down grime) rather than harsh chemicals. These jumbo-size tablets dissolve slowly to penetrate every internal part of the machine — pump, valve, basket, drum, agitator, and drain hose. Owners mention that a single tablet removed black gunk after one wash, restoring the washer’s shine where toxic competitors had failed. The fresh citrus scent comes from 100% natural orange, lemon, and grapefruit oils, so there is no synthetic perfume smell.
Effectiveness earns 101 mentions and fragrance gets 86, making this among the most balanced products in the guide. The safety and quality ratings are also strong, with 16 and 31 mentions respectively. One tablet keeps the washer clean for one month or 30 loads, so a 10-count pack lasts nearly a year. The only knock is the value-for-money score (14 mentions, mixed) — this is a premium-priced product compared to bulk options like ACTIVE. A small number of owners also note that the tablet does not always fully dissolve in cold-water cycles, though the instructions recommend hot water. Buyers who care about eco-credentials often pick Molly’s over the ACTIVE 24-pack despite the higher cost.
Why owners love it
- Enzyme-based formula removes grime without toxic chemicals
- Natural citrus scent gets 86 positive mentions — a consistent favorite
- Restored washer shine after one use, per multiple owners
- Leaping Bunny certified cruelty-free
The catch
- More expensive per tablet than bulk competitors
- May not fully dissolve in cold water cycles
Reach for this if: you want a non-toxic, natural-ingredient cleaner that still delivers serious deep-cleaning power.
pass on it if: you need a low-cost per-treatment price or only run cold-water cycles.
6. THE CLEAN PEOPLE Washing Machine Cleaner, 10 Count
A simple, nontoxic tablet that one owner calls “my go-to” for monthly maintenance.
THE CLEAN PEOPLE uses clean ingredients — no phosphates (a chemical that can harm waterways), parabens (preservatives linked to health concerns), phthalates (chemicals used in plastics), chlorine bleach, artificial dyes, or ammonia. The tablets penetrate deep inside the washer to remove grime and scale buildup, and they are safe for all machine types including top loaders, front loaders, and high-efficiency washers. Effectiveness gets 87 mentions and scent gets 39, both overwhelmingly positive. Owners note that it works better than vinegar for removing odors and leaves the machine fresh after every cycle.
The tablet is compact enough to toss in a travel bag, which a few owners appreciate. The mixed feedback comes on the residue front (10 mentions) and value for money (8 mentions). Some owners see no buildup at all after using it, while others note some residue, likely dependent on water hardness. The formula is vegan and cruelty-free, which matters for a growing segment of buyers. For those who want a vegan alternative to the Molly’s Suds option, this is your pick.
Ingredient win: Free of the harshest chemicals, including chlorine bleach and ammonia, which appeals to nontoxic households.
Travel perk: Small enough to pack for trips — owners mention taking it on the road.
Pick this for: a straightforward, vegan-friendly tablet that works well for monthly maintenance.
Consider the alternative: if you need to remove thick limescale, a liquid descaler like Glisten may work faster.
7. Glisten Washing Machine Cleaner, 12 Ounce Bottle, 3-Pack
The liquid descaler that made one machine “noticeably quieter” after a single cycle.
Glisten takes a liquid approach where most others use tablets. You pour the formula directly into the empty washer or the detergent drawer, then run a regular hot-water cycle. The liquid reaches the door seals and detergent drawer better than a tablet can, which matters if limescale (hardened mineral deposits) has built up in those hidden crevices. Customers note that after one cycle, the washer runs “noticeably quieter” and leaves clothes wetter — both signs that limescale has been removed from the heating element. For a deep clean before switching to monthly tablet maintenance, this works better than the Affresh tablet alone.
Cleaning performance gets 74 mentions and scent gets 34, both positive. The liquid also clears the moldy smell that develops on the rubber gasket (the seal around the door) of front-load machines, a common complaint. The 3-pack gives you three separate treatments, so you can do a deep clean monthly for a quarter of the year. The downside is that liquid requires you to measure and pour — less convenient than a drop-in tablet — and the bottle is larger to store.
Deep reach: Liquid flows into seals and drawers where tablets cannot reach, making it ideal for limescale removal.
Noticeable effect: Reviewers point out a quieter machine and wetter clothes after the first use, a direct result of limescale elimination.
Reach for this if: you have hard water and need to descale the drum, seals, and hidden components.
it’s not for you if: you want a no-measure, no-pour drop-and-go tablet for routine maintenance.
8. SHIMMERIX Washing Machine Cleaner Tablets, 28 Pack
A triple-layer tablet built specifically for top-load washers — not a one-size-fits-all fix.
Most washer cleaners claim universal compatibility, but SHIMMERIX specifically formulates for top-load machines. The triple-layer design targets three different residue types: buildup, scale (mineral deposits), and odors. Each layer is engineered to handle one job, so the cleaning is more thorough than a standard single-layer tablet. Shoppers say that it eliminated black streaks on white clothes and sheets — a classic sign of buildup in a top-loader — and that the effect was immediate after one cycle. Unlike the ACTIVE 24-pack which is universal, this one focuses on top-loaders.
Cleaning performance gets 80 mentions and odor removal gets 29, both positive. The tablets are septic safe and work with both high-efficiency and standard top-loaders, including brands like GE, LG, Samsung, and Whirlpool. The 28-pack covers over a year of monthly use, which is an attractive value. The main concern is residue — 12 mentions flag it as mixed. Several owners note that a white film remains after the cycle, especially in hard water, so a second rinse may be necessary.
Why it works
- Triple-layer design targets buildup, scale, and odors
- Eliminated black streaks on white clothes — a specific top-loader complaint
- 28-pack gives over a year of maintenance
The warning
- Residue noted by some owners; a rinse cycle may be needed
- Formulated for top-loaders only — not the right pick for a front-load machine
Pick this for: a top-load washer that leaves black streaks on clothes or has persistent odors.
Look elsewhere if: you own a front-loader — this is a top-load specialist.
9. Seventh Generation Washing Machine Cleaner, 6 Count
The EPA-certified, zero-scent option for households that cannot tolerate perfume.
Seventh Generation’s washing machine cleaner is EPA Safer Choice Certified and made from 92% USDA Certified Biobased ingredients (meaning 92% of the material comes from renewable biological sources). It uses oxy power (an oxygen-based stain lifter) to lift odor-causing residue without any dyes or fragrances. For anyone smell-sensitive, that is a major relief. As one owner put it: “no smell whatsoever. I’m so smell sensitive and I got nothing! I will buy it again.” The cleaning performance gets 51 mentions, and the fragrance-free aspect gets 20 mentions — both positive.
The pack includes 6 single-use pods, which is a 6-month supply. It works in all washing machines including front and top loaders and HE machines. The smaller package (6.18 x 5.24 x 1.26 inches, 4.66 ounces) stores easily in a tight cupboard. The biggest caveat is value for money — 8 mentions flag it as mixed, with some owners calling it overpriced for a 6-count. Compared to the Plink 12-count at a similar price point, you get half as many treatments. For the scent-sensitive buyer who also wants eco-credentials, this is the best fit.
The selling point
- Zero fragrance — ideal for households sensitive to smells
- EPA Safer Choice Certified, 92% biobased, Leaping Bunny certified
- Works well in LG top-loaders, a specific owner praise point
The reality check
- Only 6 treatments per box — higher per-use cost than bulk alternatives
- Mixed reviews on value for money
Go for this if: you cannot stand scented products and need a certified biobased, EPA-endorsed cleaner.
look elsewhere if: you want the most treatments per dollar — consider the ACTIVE 24-pack instead.
Understanding the Specs
Tablet vs Liquid vs Powder
Tablets are the most popular because they are drop-in simple — no measuring, no pouring, no mess. Liquids like the Glisten formula are better at reaching the drum’s hidden underside and the detergent drawer because they mix into the water immediately. Powders, such as the Tide option, activate faster than tablets and can be ideal when you want a burst of cleaning action early in the cycle, especially for hard water.
How Supply Count Affects Value
A 12-tablet pack used monthly lasts one year. A 24-pack often equals a 12-month supply (two tablets per cycle). A 6-pack covers only six months. The larger the pack, the cheaper per-treatment it usually is — but also the more storage space it requires. If you have a small laundry cabinet, a compact 6- or 10-count box may be a more practical fit even at a higher per-use cost.
