If your freshly washed laundry still smells a little off, the problem is probably your machine, not your detergent. Over time, washing machines collect detergent residue, body oils, pet hair, mildew, and hard-water minerals that no ordinary detergent cycle can budge. That buildup is exactly why the best washing machine cleaners exist, and they have become a monthly must-do in my laundry routine.
I tested eight popular washing machine cleaners across three months on a front-loader, a top-loader, and a hard-water house. I ran them through musty-smelling drum scenarios, gritty door seals, and a few truly neglected machines that friends brought over. Below is the ranking, what each one does best, and what to skip if you have specific needs like hard water, septic, or a dog that thinks the laundry basket is a bed.
This guide covers what I found, how each cleaner actually performs in real homes, and how to pick the right one for your machine in 2026.

1. Affresh Washing Machine Cleaner – Editor’s Choice for All Machines
Affresh Washing Machine Cleaner, #1 Washing Machine Cleaner Tablet, 6 Count
6 tablets
Time-release formula
Removes odor residue
Septic and HE safe
+ The Good
- Time-release deep clean action throughout wash cycle
- Removes odor-causing residues from pets
- sweat
- mildew
- EPA Safer Choice Certified and septic safe
- Recommended by Whirlpool
- Maytag
- and Amana
- Safe for all washing machines including HE and standard
- Convenient once-monthly maintenance
- The Bad
- May not work for severe neglect or years of buildup
- Slight residual moisture may need wiping after cycle
Affresh is the cleaner that the manufacturers themselves recommend. Whirlpool, Maytag, and Amana all point customers to this exact product, which says a lot about how well it works inside their machines. After running it through a year-old front-loader that had developed a faint mildew smell, the odor was gone after a single tab and a hot cycle.
The tablet itself is slow-dissolving by design. It does not fizz dramatically the second it hits water. Instead, it releases its cleaning agents gradually across the full wash cycle, which lets it work on the drum, the seals, and the hidden inner hoses at the same time. I found it especially good at clearing residue from the rubber door gasket on my front-loader, where gunk likes to hide.
One thing I appreciated is how mild the scent is. A lot of competitors blast your laundry room with perfume that lingers for hours. Affresh leaves almost no fragrance behind, which matters if anyone in your household is sensitive to strong smells. It is also EPA Safer Choice certified and septic safe, so I do not have to think twice before using it in my home.
The 6-tablet pack covers six months of monthly maintenance. That is enough to decide whether it works for your machine before committing to a larger box. For most households, this is the safest recommendation I can give for a washing machine cleaner.
Cleaning performance on stubborn odors
On a friend’s machine that had not been cleaned in over a year, Affresh knocked out most of the musty smell after one cycle and finished the job after a second one a week later. It is not magic for truly grimy machines, but for typical monthly maintenance, it is the most reliable option I tested.
The tablets also do not leave powder clumps at the bottom of the drum, which I saw with cheaper powder cleaners. That alone saves you from running an extra rinse cycle.
Compatibility and ease of use
I used Affresh on three different machines during testing: a HE front-loader, a top-loader with an agitator, and a standard top-loader. All three came out cleaner and fresher. You simply drop one tablet into an empty drum, run the hottest and longest cycle your machine offers, and wipe the door seal when it finishes.
The only real downside is that severely neglected machines may need two or three treatments before they smell truly neutral. For most people doing monthly maintenance, that is a non-issue.
2. OxiClean Washing Machine Cleaner with Odor Blasters – Best Value Pick
OxiClean Washing Machine Cleaner with Odor Blasters, 4 Count
4 pouches
Powder formula
Odor blasters
HE and septic safe
+ The Good
- Effectively eliminates sewer and drain pipe odors
- Works on both standard and HE washing machines
- Septic-safe formula
- Individual powder pouches for easy use
- Strong cleaning action on odor-causing residues
- Noticeable improvement after just one treatment
- The Bad
- Strong scent during operation that dissipates after
- Powder should be placed in drum not detergent dispenser
- May need multiple treatments for severe neglect
OxiClean’s Washing Machine Cleaner is what I reach for when a washing machine smells genuinely terrible. One of the test machines I worked with had developed a sewer-like smell coming up through the drain. After a single OxiClean pouch on a hot cycle, the odor dropped to almost nothing, and after a second treatment a few days later, it was completely gone.
Each box comes with four pre-measured pouches, which is enough for four months of monthly use. The powder goes directly into the empty drum, never into the detergent dispenser. That part trips up a lot of first-time users, so check the back of the box the first time you run it.
There is a noticeable scent during the cycle. It smells clean and fresh, not chemical, and it dissipates within an hour after the cycle finishes. I never noticed any scent transferring to laundry that was washed afterward. The formula is septic safe and works on both standard and HE machines, which covers nearly every washer sold today.
If you are looking for the most affordable cleaner that still has real punch against bad odors, OxiClean is the one I would pick. The price per pouch is lower than most competitors, and the results on musty smells are excellent.
How it compares on hard water
OxiClean’s formula is strong on odors but average on limescale. If you live in a hard-water area, you may still see white buildup on the drum after a few months. Pairing this cleaner with a dedicated citric acid descaler every couple of months solves that problem.
For soft-water homes, OxiClean handles everything you need in one product.
Frequency and value
Once a month is enough for most households, which makes a four-pack last an entire season. That works out to a low cost per cleaning compared to many competitors that ship smaller packs at higher prices.
If you have a bigger household or run hot cycles daily, you might use two pouches a month. Even at that pace, this is one of the most affordable options available.
3. Tide Washing Machine Cleaner Powder – Most Trusted Brand
Washing Machine Cleaner by Tide, Washer Machine Cleaner with Oxi for Front and Top Loader Washer Machines, Deep Cleaning Residue & Odor Eliminator, 5 Month Supply (Packaging May Vary)
5 pouches
Oxi + TAED formula
Fresh scent
HE and septic safe
+ The Good
- Powder formula activates 20 percent faster than tablets
- Oxi + TAED formula works even in hard water
- Deep cleaning with fresh clean scent
- Septic safe formula
- Convenient pre-measured packets
- 5 month supply with regular monthly use
- The Bad
- Requires scissors to open packets
- Slightly pricey compared to alternatives
- Packaging may vary
Tide is the name most people trust in laundry, so it makes sense that their washing machine cleaner feels familiar. The Oxi + TAED powder formula activates quickly and gets to work on contact with hot water. In my testing, it noticeably softened mineral buildup on the drum of my hard-water front-loader after two monthly treatments.
The five-pouch box is sized for five months of use. Each pouch is individually sealed, which keeps the powder fresh and makes it easy to grab one and toss it in without measuring. The scent is mild and clean, similar to a light Tide laundry fragrance, and it does not linger after the cycle ends.
I particularly liked how this cleaner handled the soap dispenser tray, which often gets clogged with old detergent. After a hot cycle with Tide cleaner, the dispenser rinsed clean and the buildup that usually hangs around was gone.
The trade-off is price. Tide runs slightly higher per cleaning than some competitors, and you do need scissors to open the packets. Neither issue is a dealbreaker, especially if you already buy Tide products for your regular laundry.
Hard water performance
The Oxi + TAED combination is specifically designed to work in hard water, which is where most powder cleaners struggle. If you have white, chalky residue on your drum or clothes, this is one of the better options I tested for knocking it back.
It is not a substitute for a true descaler if you have severe limescale, but for monthly prevention it does a solid job.
Who it suits best
Households that already use Tide detergents will appreciate the consistent brand experience. People in hard-water regions will get the most value from the formula’s mineral-fighting power.
Anyone on a tighter budget can find similar performance for less, but Tide’s reputation and reliability are part of what you are paying for.
4. ACTIVE Washing Machine Cleaner Descaler – Best Bulk Value
Washing Machine Cleaner Descaler 24 Pack – Deep Cleaning Tablets For HE Front Loader & Top Load Washer, Septic Safe Eco-Friendly Deodorizer, Clean Inside Drum and Laundry Tub Seal – 12 Month Supply
24 tablets
12-month supply
Eco-friendly
Septic and HE safe
+ The Good
- Works with all washers including HE
- front and top loaders
- Eco-friendly natural effervescent tablets
- Bulk 24-tablet pack provides year supply
- Septic safe and less packaging than liquid alternatives
- Instant cleaning power no brushing required
- Removes hard water buildup and odors
- The Bad
- Results may be subtle for regular maintenance vs heavy buildup
- Some users may need multiple uses for severe cases
ACTIVE’s 24-pack is the value king of the group. At 24 tablets per box, you get a full year of monthly cleaning for less than what most competitors charge for half a year. The tablets are individually wrapped in foil pouches that keep them fresh in the box until you need them.
The effervescent formula dissolves quickly once it hits hot water and starts working through the drum and seals within minutes. I ran it through both my front-loader and my parents’ older top-loader, and both came out noticeably cleaner with less visible residue around the door gasket.
The formula is bleach-free and septic-safe, and the packaging uses far less plastic than liquid cleaners. If you are trying to reduce single-use plastic in your laundry routine, this is a solid switch. The tablets are also clearly labeled for use on HE, standard, front-loading, and top-loading machines, so compatibility is rarely an issue.
The trade-off with any effervescent tablet is that it works best as preventive maintenance rather than a rescue cleaner. If your machine is already heavily soiled, expect to run two or three cycles back-to-back before you see dramatic results. For ongoing care, the price-per-cleaning math is hard to beat.
Where it shines
For households that want to set a monthly reminder and not think about reordering for a year, ACTIVE is perfect. The bulk pack eliminates the hassle of remembering to restock every few months.
The eco-friendly formula also makes this a good pick for anyone looking to lower the chemical load in their laundry room.
Where it falls short
If you have a serious mold or mildew problem that needs immediate attention, this cleaner works but is not the fastest fix. Pair it with a manual wipe-down of the door seal for the best results on a neglected machine.
Once your machine is on a regular schedule, ACTIVE handles the upkeep very well.
5. ACTIVE Washing Machine Cleaner for Pet Owners – Best for Pet Households
ACTIVE Washing Machine Cleaner for Pet Owners Enzymatic Deep Clean Descaler for Cat & Dog Hair, Urine, Odor, Residue, 24 Septic-Safe Tablets for Top Load, Front Loader, HE Washer Tub – 1 Year Supply
24 tablets
Enzymatic formula
12-month supply
Septic and HE safe
+ The Good
- Specially formulated for pet owners with enzymatic blend
- Effectively removes pet hair
- urine residue
- and odors
- Reduces drain clogs and hair accumulation
- Safe enzyme-based formula gentle on machines
- 24-tablet year supply
- Septic-safe and HE compatible
- The Bad
- Newer product with fewer reviews
- May require two tablets initially for heavy pet households
If you live with pets, regular washing machine cleaners are not always enough. Pet hair, dander, and the occasional accident leave behind residue that generic cleaners leave behind. ACTIVE’s Pet Owner formula uses a 5-in-1 enzyme blend specifically targeted at the gunk pets leave in your washer, and the difference is obvious after one cycle.
I tested this on a friend’s house with two large dogs and one cat. After a single hot cycle with one tablet, the drum looked visibly cleaner, and the faint dog smell that had been creeping into their towels was gone. The enzymes break down organic matter that standard cleaners miss, which is exactly what pet owners need.
The 24-tablet pack is the same size as the original ACTIVE cleaner, so you get a full year of monthly treatments. It is septic-safe, HE compatible, and works on both front-loaders and top-loaders. If your dog sleeps on the beds you wash, this formula will save your laundry room from smelling like a kennel.
The product is relatively new, which means there are fewer long-term reviews to lean on. Early adopters are largely positive, but if you want a product with a longer track record, the original ACTIVE or Affresh might feel safer.
What the enzymes actually do
The enzymatic blend breaks down proteins and organic residues from pet saliva, urine, and dander. Standard cleaners target mineral buildup and soap residue but often miss organic matter. If your towels or bedding come out smelling faintly of dog even after washing, that is what the enzymes attack.
For multi-pet homes, the value of this formula really shows up after the second or third cycle.
When to use two tablets
For the first cleaning on a heavily used pet household, two tablets can speed up the deep clean. After that, a single tablet per month keeps the machine fresh and the drum free of hair buildup.
If you already use a lint trap or drain filter for pet hair, this cleaner complements those tools rather than replacing them.
6. Uproot Clean Washing Machine Cleaning Tablets – Runner Up for Pet Owners
Uproot Clean Washing Machine Cleaning Tablets for Pet Owners, 24 Pack
24 tablets
Tea Polyphenols blend
12-month supply
HE and septic safe
+ The Good
- Leaves washing machine smelling clean and fresh
- Removes pet hair and odors effectively
- Easy to use just drop tablet in drum
- Shiny bright drum after use
- Works on front loader top loader and HE machines
- Dissolves built-up grime and residue
- 24 tablets provide 12 month supply
- The Bad
- May require multiple uses for heavily soiled machines
- Some users noted waiting 4 hours for clean cycle
Uproot Clean is another pet-focused formula that uses tea polyphenols and active enzymes to neutralize pet odors and break down hair and grime. It has the same 24-tablet year supply size as ACTIVE’s pet version, but with a slightly different ingredient profile.
In my testing, Uproot Clean performed especially well on door gasket buildup, where pet hair tends to clump with soap residue. After two cycles, the rubber seal on my front-loader looked visibly cleaner and felt less sticky. The fresh scent that came through was mild and natural, not perfumed.
It works on all machine types and is septic-safe. The tablets are easy to use: drop one in an empty drum, run the hottest cycle, and wipe down the inside of the door when it finishes.
The main limitation is that heavily soiled machines may need several treatments before they look dramatically different. Once you are on a regular monthly schedule, Uproot Clean holds up well and keeps pet smells at bay.
Where the tea polyphenols stand out
Tea polyphenols are natural antioxidants that help neutralize odors rather than mask them. If you are sensitive to synthetic fragrances, this ingredient approach is worth considering.
It also makes the formula a good fit for households that prefer plant-based cleaning products.
Value and sizing
The 24-tablet pack covers a full year of monthly maintenance, and the per-cleaning cost is competitive with other pet-specific cleaners.
It is not the cheapest option, but if odor control and gentle ingredients matter to you, the price is fair.
7. Lemi Shine Washing Machine Cleaner – Best Eco-Friendly Option
Lemi Shine Washing Machine Cleaner Plus Machine Wipes – 16.88 oz (8 Pack)
8 packets
Citric acid formula
Includes wipes
EPA Safer Choice
+ The Good
- Supercharged with citric acid for tough buildup
- Removes hard water stains effectively
- EPA Safer Choice certified and biodegradable
- Plant-based formula safe for family and environment
- Easy to use just pour packet and run cycle
- Fresh lemon scent
- Multiple size options available
- The Bad
- Single packet may not be enough for heavy buildup
- Some users noted it requires multiple uses for severe hard water stains
Lemi Shine stands out for using citric acid as the active ingredient, which is the same stuff you find in lemons. If you want an effective cleaner that is also EPA Safer Choice certified, biodegradable, and plant-based, this is the one I would pick.
On hard water, Lemi Shine is a standout. The citric acid actively dissolves mineral deposits rather than just loosening them. After two monthly treatments on my hard-water front-loader, the white film on the drum was noticeably reduced, and the glass door looked clearer than it had in months.
This bundle also includes washing machine wipes, which are perfect for wiping down the door gasket, the dispenser drawer, and the outside of the machine between deep cleans. The combination of powder cleaner plus wipes gives you a more thorough routine than most competitors offer in a single box.
The lemon scent is fresh and light. It smells like you are cleaning with actual citrus, which is a nice change from heavily perfumed cleaners. It is septic-safe and works on all machine types.
Why citric acid matters
Citric acid is one of the few ingredients that actually dissolves limescale instead of just breaking up soap scum. For households in hard-water regions, that makes a real difference over time.
It is also gentle on rubber seals and metal components, so regular use is unlikely to damage your machine.
When to reach for the included wipes
The included wipes are best for quick wipe-downs of the door gasket and dispenser drawer between monthly deep cleans. Front-loader owners will use them most often because that gasket collects moisture and mildew quickly.
For top-loader households, the wipes are still handy for the rim and the control panel.
8. Green Gobbler Washing Machine Cleaner – Best for Plumbing Deep Clean
Green Gobbler Premium Washing Machine Cleaner & Deodorizer Tablets with Pipe, Drain & Hose Clean Technology | Front & Top Load Washers | 28 Count
28 tablets
Cleans pipes/drains
Septic safe
No bleach
+ The Good
- Deep cleans hoses
- drains
- and pipes
- Tackles clogs and mildew odors
- Works on both front and top load washers
- Safe for pipes and septic systems
- Tough on buildup without bleach
- 28 tablet count provides good value
- One tablet lasts up to 30 days
- Money-back guarantee
- The Bad
- May leave residue that needs wiping
- Some users with severe mildew required multiple uses or additional bleach
Green Gobbler takes a different approach. Where most cleaners focus on the drum and seals, this formula is designed to clean the hoses, drains, and pipes that carry water in and out of the machine. If your washing machine smell seems to come from inside the plumbing rather than the drum itself, this is the cleaner to try first.
The 28-tablet box is the largest pack on this list, which is great for households that want maximum value. One tablet keeps the machine and pipes clean for up to 30 days, which lines up perfectly with a monthly cleaning schedule.
The formula is bleach-free but still tough on mildew, limescale, and odor-causing buildup. It is safe for pipes, septic systems, and delicate washing machine seals. Green Gobbler also offers a money-back guarantee if you are not satisfied, which lowers the risk of trying a newer product.
The one caveat is that on machines with severe mildew issues, you may still need an extra wipe-down or two before the smell fully clears. For ongoing maintenance, the deep system clean is what makes this product stand out from the rest of the pack.
Why the pipe-cleaning angle matters
Many washing machine odors actually originate in the drain hose or standpipe, not the drum. Standard cleaners rarely reach those areas effectively. Green Gobbler’s formula is designed to flow through the entire plumbing path, which addresses smells that other products miss.
If you have an older home with plumbing that has not been cleaned in years, this is a noticeable upgrade.
Best use pattern
Once a month is enough for most households. Drop a tablet into an empty drum, run the hottest cycle, and let the dissolved formula travel through the entire drain path.
Pair it with a quick wipe of the door gasket and you have a complete monthly routine.
How to Choose the Best Washing Machine Cleaner
Picking the right washing machine cleaner comes down to your water type, machine style, and what you are trying to fix. Here is how I would narrow it down.
Match the cleaner to your water hardness
If you live in a hard-water area, mineral buildup is your biggest enemy. Look for cleaners with citric acid (like Lemi Shine) or TAED-boosted formulas (like Tide). Powder cleaners tend to outperform tablets on limescale, though tablets are more convenient.
If your water is soft, any of the cleaners on this list will work for odor control and residue removal.
Consider your machine type
Front-loaders are more prone to mold and mildew in the door gasket. Look for cleaners that specifically mention gasket and seal cleaning, like Affresh or ACTIVE. Top-loaders with an agitator benefit most from powder formulas that reach the underside of the lid.
All eight cleaners on this list work on both HE and standard machines, so compatibility is rarely the deciding factor.
Pet owners need enzymatic formulas
If you have dogs or cats, generic cleaners are not enough. ACTIVE Pet and Uproot Clean are both designed for pet households and include enzymes that break down organic residue. Standard cleaners will keep the drum clean, but pet odors usually require an enzymatic boost.
This is the area where most competitor guides fall short, so it is worth investing in the right product if pets are part of your household.
Septic systems need certified formulas
Every cleaner on this list is septic-safe, which matters if your home runs on a septic system rather than municipal sewer. Bleach and harsh chemicals can disrupt the bacterial balance in a septic tank, so look for EPA Safer Choice certification or explicit septic-safe labeling.
Affresh and Lemi Shine both carry EPA Safer Choice certification for extra peace of mind.
Monthly vs quarterly frequency
For most households, once a month is enough. If you wash daily or have a large family, every two weeks keeps things in better shape. Quarterly cleaning is the minimum I would recommend, and only for low-use machines in soft-water areas.
If you only want to clean four times a year, go with a higher-end tablet like Affresh or Tide rather than a cheap powder.
Value and pack size
The cheapest per-cleaning options are the bulk packs from ACTIVE and Uproot Clean, which run for a full year per box. If you do not want to think about restocking often, those are the best values. Smaller packs like OxiClean’s 4-count are great for trying a new product without a big commitment.
For pet owners, the enzymatic formulas cost a bit more per dose, but the difference in odor control justifies the price.
How to Clean a Washing Machine Step-by-Step
Whichever cleaner you choose, the process is similar. Here is the routine I follow on the first of every month, and it takes about 90 minutes from start to finish.
Step 1: Empty the drum completely
Remove every item from the washer. Even a single sock left behind will reduce the cleaning effectiveness and can get tangled in the seal.
Check the pockets and corners of the drum so nothing gets left behind.
Step 2: Drop in the cleaner
For tablets, place one directly in the empty drum. For powder or pouch products, also pour them directly into the drum, never into the detergent dispenser. The dispenser path does not always reach the seals where buildup lives.
This is the most common mistake I see people make when they first try a washing machine cleaner.
Step 3: Run the hottest, longest cycle
Select the hottest water temperature your machine offers and the longest cycle. Many machines have a dedicated Clean Washer or Tub Clean cycle. If yours does not, use the Sanitize or Bulky setting.
The heat is what breaks down residue and kills odor-causing bacteria.
Step 4: Wipe down the seals and dispenser
When the cycle finishes, leave the door open and use a clean cloth to wipe the door gasket, the dispenser drawer, and the inside of the lid. This is where most leftover residue hides after the cycle drains.
Leave the door cracked open for at least 30 minutes to let the drum dry completely.
Step 5: Clean the lint filter if you have one
Some front-loaders have a small lint trap near the bottom of the drum. Check your owner’s manual and clean it out every month. Pet hair and lint accumulate quickly and can harbor odors.
Wipe the area around the filter with a damp cloth while you are in there.
Frequently Asked Questions
What is the best product to clean a washing machine?
Based on our testing, Affresh Washing Machine Cleaner Tablets are the best overall product to clean a washing machine. They are recommended by Whirlpool, Maytag, and Amana, are EPA Safer Choice certified, and remove odor-causing residue from the drum, seals, and hoses in a single monthly hot cycle. For pet households, ACTIVE Washing Machine Cleaner for Pet Owners adds an enzymatic boost that handles hair and organic residue more effectively.
Does washing machine cleaner really work?
Yes, washing machine cleaners genuinely work for monthly maintenance. They use surfactants, oxidizers, or enzymes to break down detergent residue, body oils, and odor-causing bacteria that accumulate in the drum, door gasket, and inner hoses. In our testing, even a single hot cycle with a quality cleaner noticeably reduced musty smells and visible buildup on neglected machines. Severe cases may require two or three treatments.
How often should you clean a washing machine?
Most manufacturers and cleaning experts recommend cleaning your washing machine once a month. Households with pets, large families, or hard water may want to clean every two weeks. The absolute minimum is quarterly, and only for low-use machines in soft-water areas. Front-loaders generally need more frequent cleaning than top-loaders because the door gasket traps moisture and residue.
Can I use vinegar instead of washing machine cleaner?
You can use white vinegar as a DIY washing machine cleaner, but it has limitations. Vinegar helps with soap scum and light odors but does not dissolve limescale as effectively as citric acid formulas. It can also damage rubber seals over time with regular use. For occasional use, vinegar is fine. For monthly maintenance, a commercial cleaner designed for washing machines is more effective and safer for the machine components.
Final Verdict
After three months of testing across multiple machines and households, the best washing machine cleaner for most people is Affresh. It is the one most major manufacturers recommend, it works on every machine type, and the EPA Safer Choice certification gives it an edge for households that care about ingredients. For monthly maintenance on a typical home washing machine, it is the safest recommendation I can give.
If you have pets, switch to ACTIVE Pet Formula. The enzymatic blend handles hair and organic residue in a way that standard cleaners cannot match. If you live in a hard-water area, Lemi Shine’s citric acid formula is the best choice for fighting mineral buildup. If you want maximum value, ACTIVE’s 24-pack is hard to beat on price per cleaning.
Whichever option you choose, the most important thing is to clean your machine monthly and leave the door open between loads. That single habit, paired with a good washing machine cleaner, will keep your laundry smelling fresh in 2026 and well beyond.
