9 Best Natural Washing Machine Cleaners (November 2026)
The best natural washing machine cleaners include the Affresh Washing Machine Cleaner for simple monthly care, the ACTIVE Washing Machine Cleaner for Pet Owners for pet households, and the ACTIVE Washing Machine Cleaner Descaler 24 Pack for hard-water buildup.
On this page (5 sections)
The best natural washing machine cleaner for most homes is Affresh Washing Machine Cleaner, because it combines a monthly tablet routine with front-load, top-load, HE and septic-safe compatibility. That makes it a simple starting point for everyday maintenance.
Choose ACTIVE Pet Owners for pet residue, ACTIVE Descaler for hard water, or Lemi Shine for citric acid. We compared options by formula, washer compatibility, supply size, odor focus, residue removal and ease of use.
Natural does not mean every formula works the same way. Match the cleaner to the buildup you see, since pet residue, limescale and soap scum each point to a different approach.
Residue also collects differently by machine type. Front-load machines can hold residue around the door seal and drum folds, while top-load machines can build it up around the agitator, tub and filter area.
HE washers use less water, which can make soap and mineral residue more noticeable over time. Supply size and scent also matter, as some formulas are unscented and others leave a fresh finish.

Place the tablet in the empty drum, run the cycle named in the directions, then leave the door ajar and wipe reachable seals. A maintenance cleaner cannot fix a leak, a blocked drain or a worn seal.

The best natural washing machine cleaners for different needs
Affresh is the easiest general choice, while the other products fit specific problems such as pet residue, hard water, fragrance preferences or drain buildup. The scores weigh specs, features and buyer feedback against the needs of someone shopping for a natural washing machine cleaner.
Affresh Washing Machine Cleaner: Best for simple monthly care
- 12 tablets
- Time-release cleaning action
- EPA Safer Choice Certified
- Septic safe
A straightforward monthly tablet for buyers who want broad washer compatibility and a simple routine. Affresh also targets residue linked with pet, sweat and mildew odors.
Pros
- Monthly use
- All washer makes and models
- Septic safe
Cons
- Only 12 tablets
- Tablet format may not suit powder buyers
Affresh is the best starting point for a simple maintenance schedule. The pack contains 12 tablets, designed for one tablet once a month.
That schedule suits buyers who want a clear habit they can repeat without doing math each time. One tablet in an empty washer fits most households, especially when you already run a monthly clean cycle.
Its time-release action keeps working through the wash cycle against bacteria, grime and soap scum. The cleaner is aimed at places you cannot easily scrub, such as the pump, drum and filter area.
Affresh also targets residues that can hold pet, sweat and mildew odors. Those residues can transfer a stale smell to towels, sheets and everyday clothing, even when laundry was washed well.
The formula is EPA Safer Choice Certified and septic safe. It works with all washing machine makes and models, including front-load, top-load and HE washers.
That broad compatibility makes it a low-effort choice for homes that do not want to match a product to a specific brand. The main trade-off is coverage, since a 12-tablet pack fits a standard monthly routine but not twice-monthly cleaning.
Keep the pack dry and closed so the tablets stay ready for the next monthly run.
ACTIVE Washing Machine Cleaner for Pet Owners: Best for pet households
- 24 septic-safe tablets
- 5-in-1 enzyme blend
- 12-month supply
- For pet hair, urine, odor and residue
This is the most targeted option here for homes dealing with pet hair, urine odor and residue. The 24-tablet pack supports monthly use or the twice-monthly routine described for this formula.
Pros
- Pet-focused formula
- 24-tablet pack
- Septic safe
Cons
- Twice-monthly use is advised in its instructions
- More tablets than a basic annual routine needs
ACTIVE Pet Owners is the most focused option for homes with cats or dogs. Its 24-tablet pack uses a 5-in-1 active enzyme blend aimed at pet hair, urine, odor, oil, soap and limescale.
That focus suits pet bedding, towels and blankets that can leave hair and organic residue behind. Pet residue differs from plain soap scum, so an enzyme formula can be a closer match.
The product is septic safe and compatible with HE, front-loading and top-loading washers. That makes it practical for many pet households, including those with septic systems.
ACTIVE describes monthly use and also says to repeat twice a month for year-round care. At two tablets a month, the pack would last about six months rather than a full year.
Use the tablet in the empty washer, not the detergent drawer. After the cycle, wipe reachable residue from the seal or tub edge with a clean towel.
It can also help reduce drain clogs and hair accumulation linked to pet hair buildup. Keep clothes fresh without pet fur clinging from residue left in the machine.
ACTIVE Washing Machine Cleaner Descaler 24 Pack: Best for hard-water buildup
- 24 tablets
- Natural material features
- Bleach free
- Unscented descaler
Choose this ACTIVE formula when limescale and mineral deposits matter as much as odor. It uses 24 concentrated tablets in a resealable bulk box for a 12-month supply.
Pros
- Descaling focus
- Unscented
- Bleach free
Cons
- Not for dryers
- Bulk box needs dry storage
ACTIVE Descaler is the strongest match for mineral buildup. Its 24 natural, bleach-free and unscented tablets break down hard-water deposits while deodorizing the basket, gasket and internal parts.
That makes it a good fit for homes where white mineral residue shows up on the drum or around the seal. Hard water can leave deposits that trap odor, so addressing the mineral side can help the machine smell fresher.
The resealable bulk box provides a 12-month supply when used monthly. It also helps you keep the remaining tablets dry and organized between uses.
The tablets work with HE and standard top-load washers, as well as front-load models. That range covers most home setups, provided you use the product in a washing machine as directed.
Choose this formula when limescale is a bigger concern than fragrance. The unscented finish can suit buyers who prefer cleaning without added scent on the machine or on later loads.
It is intended for washing machines, not dryers. The tablet is designed to dissolve and circulate in wash water, so use it only in the appliance named in its directions.
For routine care, pair monthly cleaning with wiping the door seal and leaving the door open after washing. Those habits help prevent damp residue from sitting in folds.
True Fresh Washing Machine Cleaner Tablets: Best for a year of monthly maintenance
- 25 tablets
- Oxygen-based formula
- Descaling action
- Septic safe
A 25-tablet box gives you one extra tablet beyond a typical 12-month routine. The oxygen-based formula targets residue, limescale and trapped smells in the drum, pump, valves and hoses.
Pros
- 25-tablet supply
- Broad washer compatibility
- Septic safe
Cons
- Less targeted for pet homes than ACTIVE Pet Owners
- Tablet-only format
True Fresh offers 25 oxygen-based tablets for buyers who want a full year of monthly cleaning with one extra dose. The extra tablet can be useful as a spare for a busy month or a deeper refresh.
Its formula targets residue and mineral deposits in the drum, pump, valves and hoses. Those areas are hard to reach by hand, which is why a cleaner that circulates through the wash cycle can be helpful.
The tablets are compatible with HE, front-load and top-load washers. That broad fit makes the product easier to choose when you want one routine across different machine types.
True Fresh also identifies the formula as septic safe. That can matter for homes that need to consider what goes down the drain.
This is a balanced choice for general residue, odor and limescale maintenance. It does not narrow itself to one problem, so it can suit homes that see a little of each.
It is less specifically aimed at pet buildup than ACTIVE Pet Owners, but the extra tablet gives you a useful spare. Pet households with heavy hair may want a more targeted enzyme formula.
For set-up, drop one tablet into the empty drum and run a normal or hot cycle as directed. Running the washer empty lets the tablet work without laundry absorbing the cleaning action.
Buyers who prefer powder may want a powder option, and buyers with a single clear problem may prefer a formula aimed at that problem.
ECO-GALS Washing Machine Cleaner and Deodorizer: Best for fresh-scent maintenance
- Year's supply
- Fresh scent
- For front-load, top-load and HE washers
- Targets pet hair and debris
ECO-GALS fits buyers who want monthly maintenance with a fresh scent rather than an unscented finish. It is designed for residue and debris in the drum, pipes and filter.
Pros
- Monthly routine
- Fresh scent
- All major washer types
Cons
- Scent may not suit fragrance-sensitive homes
- The box count is not stated here
ECO-GALS suits buyers who want a fresh scent during regular washer care. The product is designed for front-load, top-load and high-efficiency washers, with a monthly tablet routine.
That combination can suit homes where a light fresh finish matters as much as cleaning. A monthly rhythm is also easier to maintain than a more frequent schedule.
It targets pet hair and debris in the drum, pipes and filter. Those areas can hold material that does not rinse away with regular laundry cycles.
The fresh scent is lighter than a loud perfume according to the product description, but fragrance preferences vary. Homes that prefer unscented cleaning may want to choose a different formula.
The main unknown for planning is the exact tablet count in the supplied facts. That makes it harder to calculate how long one pack will last before you need to reorder.
Choose it when scent matters more than calculating a precise annual supply. If you like a fresh finish after a clean cycle, that priority may outweigh the count question.
For daily use, the routine is simple. Place the tablet in the empty washer, choose the hot or clean cycle named in the directions, and let the machine finish the full run.
The trade-off is that scented and unscented buyers want opposite things. Format also matters, since tablet users and powder users will make different choices here.
Tide Washing Machine Cleaner 52 Week Supply: Best for powder packets
- 52-week supply
- Powder packets
- Oxi plus TAED
- Septic safe
Tide is the clear fit if you prefer individually portioned powder instead of tablets. Its Oxi plus TAED formula is designed to lift odor-causing residue and work in hard water.
Pros
- Full 52-week supply
- Powder format
- Hard-water cleaning focus
Cons
- Scented formula
- Not described for HE washers in the supplied product facts
Tide is the right format for buyers who prefer powder packets instead of tablets. The 52-week supply is designed for 12 months of cleaning on front-load and top-load washer machines.
Powder can suit buyers who want a format that dissolves quickly and feels easy to pour into the drum. Single packets also help with portioning, since each one is measured for one clean.
Its Oxi plus TAED formula targets odor-causing residue and deposits. That focus makes it relevant for homes where odor seems tied to buildup inside the machine rather than to laundry itself.
Tide also describes the powder as septic safe and designed to activate faster than tablets. Faster activation can be appealing when you want the cleaning action to start early in the cycle.
This pick makes sense when hard-water cleaning and a scented finish are both useful. TAED is described as supporting cleaning action even in hard water, which can matter in mineral-heavy areas.
The supplied facts do not describe it for HE washers, so HE owners should confirm compatibility before choosing it. That check is important because HE machines use less water and can have different cycle needs.
The trade-off is scent and format. Buyers who prefer unscented cleaning or tablets may want another option, while powder fans may prefer this format.
For care, follow the packet directions and run the washer empty. Wiping the drum edge and seal after the cycle can help remove loosened residue.
Lemi Shine Washing Machine Cleaner Plus Machine Wipes: Best for citric acid cleaning
- Citric acid formula
- Plant-based
- Biodegradable
- EPA Safer Choice certified
Lemi Shine suits buyers who specifically want citric acid and a plant-based, biodegradable formula. The pack also includes machine wipes for cleaning reachable surfaces.
Pros
- Citric acid focus
- Plant-based formula
- Wipes included
Cons
- Only 8 packs
- Less annual coverage than 24-tablet options
Lemi Shine is the clearest option for a citric acid washing machine cleaner. Its plant-based, biodegradable formula uses citric acid to target odor-causing buildup and hard-water stains.
Citric acid is often chosen for mineral residue because it can help break down deposits left by hard water. That makes this option relevant for homes where residue looks chalky or crusty.
The pack is an 8-pack weighing 16.88 oz and includes machine wipes. The wipes can be useful for reachable surfaces, such as the drum edge, door seal or dispenser area.
Monthly use makes this a shorter-maintenance supply than the 24- or 25-tablet options. Buyers who want a full year from one pack may need to plan for more than one purchase.
Lemi Shine is EPA Safer Choice certified and suits buyers who want a formula built around citric acid. It can also suit households that prefer plant-based cleaning products.
It is also useful when you want wipes for reachable machine surfaces as part of the routine. A combined approach can help because a circulating cleaner may not remove every bit of residue from folds and edges.
The trade-off is coverage and format. Fewer packs and a wipes-included setup may not suit buyers who want the simplest tablet routine.
For set-up, follow the directions for the cleaner and use the wipes as intended on reachable surfaces. Keeping the routine monthly can help prevent buildup from becoming harder to remove.
Green Gobbler Premium Washing Machine Cleaner: Best for pipes and drains
- 28 tablets
- Pipe, drain and hose cleaning technology
- Bleach free
- Septic safe
Green Gobbler is the strongest choice when buildup in hoses, drains and pipes is your main concern. It also targets limescale and mold or mildew stains without bleach.
Pros
- 28-tablet supply
- Drain and hose focus
- Septic safe
Cons
- More system-focused than scent-focused
- Money-back guarantee terms should be checked before ordering
Green Gobbler is built around the washer's wider drainage system. Its 28 tablets target buildup in hoses, drains and pipes, as well as odor, limescale and mold or mildew stains.
That system focus can matter when odor seems to come from the drain path rather than from the visible drum. Residue in hoses and pipes can sit damp and hold smells between washes.
The formula is bleach free, septic safe and suitable for front-load, top-load and HE washers. Those details make it easier to consider for a range of home setups.
One tablet is designed to keep the machine and pipes clean and clear for up to 30 days. That monthly rhythm aligns with the maintenance schedule used by many of the other options here.
Choose this product when smells seem connected to the drain path rather than only the drum. It may also suit homes where slow drainage or musty odor keeps returning after basic cleaning.
Its focus is system cleaning, so it may be more than you need for light monthly maintenance. Homes with only mild residue may prefer a simpler general tablet.
The 28-tablet count gives more supply for frequent monthly use. That can be helpful if you clean on a strict schedule or want extra tablets on hand.
For care, run the tablet in an empty washer on the cycle named in the directions. Wiping the seal and dispenser between cleans can help reduce residue that the tablet cannot reach.
Renuv® Heavy Duty Washing Machine Cleaner: Best for extra-large tablets
- 40-gram tablets
- 6-month supply
- Unscented
- Time-release formula
Renuv uses six extra-large 40-gram tablets for buyers who prefer fewer, larger doses. Its unscented time-release formula targets residue in the drum, pump, tub, valve, agitator, filter and hose.
Pros
- Extra-large tablets
- Unscented
- Six-month supply
Cons
- Only six tablets
- Shorter coverage than annual packs
Renuv is the best fit for buyers who prefer fewer, larger doses. Each tablet weighs 40 grams, and the six-tablet pack provides six months of monthly maintenance.
Larger tablets can simplify dosing because you do not need to use several smaller tablets at once. That can be appealing when you want a straightforward monthly routine.
The unscented, time-release formula targets buildup and odor-causing residue in the pump, drum, tub, valve, agitator, filter and hose. Slow dissolving can help the cleaner keep working through more of the cycle.
It works with front-load, top-load and HE washers. That compatibility makes it easier to use across common home machines without matching it to one brand.
The white tablets are also described as preserving laundry compared with colored tablets. Buyers who worry about color transfer may find that detail useful.
Large tablets can simplify dosing, but six months of supply means you will replace the pack sooner than a 24- or 25-tablet option. That shorter coverage is the main planning trade-off.
Choose Renuv when tablet size matters more than annual coverage. It can suit buyers who want a simpler dose and do not mind reordering sooner.
For set-up, use one tablet in the empty drum as directed and run the appropriate cycle. Keeping the pack stored dry will help the tablets stay in good condition.
How natural washing machine cleaners differ
Natural washing machine cleaners use different approaches, including enzymes, oxygen based ingredients, citric acid, descalers and effervescent tablets. The best match depends on your main issue, whether that is pet residue, mineral buildup, odor or general care.
Enzyme formulas target organic residue such as pet hair, urine, oils and sweat. ACTIVE Pet Owners is the most targeted option here for pet homes.
Oxygen based formulas target residue and trapped odor. True Fresh uses this approach for buildup in the drum, pump, valves and hoses.
Citric acid formulas take another route. Lemi Shine centers on citric acid for odor causing buildup and hard water stains.
Descalers focus more directly on limescale and mineral deposits. ACTIVE Descaler, True Fresh, Tide, Lemi Shine, Green Gobbler and Renuv all describe some form of mineral or hard water cleaning.
Effervescent tablets dissolve and circulate through wash water. That helps reach pumps, filters and hoses, and each tablet is portioned for one clean.
Powder packets are another format. Tide is the powder option here, and some buyers prefer it because it activates quickly and pours easily into the drum.
Scent and septic safety also differ. ACTIVE Descaler and Renuv are unscented, while ECO-GALS and Tide leave a fresh scented finish.
Affresh, ACTIVE Pet Owners, ACTIVE Descaler, True Fresh, Tide and Green Gobbler are identified as septic safe. Read our guide to what washing machine cleaner is made of for more detail.
Supply size affects value too. A 24 or 25 tablet pack can cover a year of monthly cleaning, while a six tablet pack covers six months.
How to choose a natural washing machine cleaner
Start with the washer type. Front-load, top-load and HE compatibility is stated for Affresh, ACTIVE Pet Owners, ACTIVE Descaler, True Fresh, ECO-GALS, Green Gobbler and Renuv.
Tide is described for front-load and top-load machines in the supplied facts.
Next, choose the main cleaning target. Pet homes should consider ACTIVE Pet Owners.
Hard-water homes should look first at ACTIVE Descaler or Lemi Shine. Drain and hose odors point toward Green Gobbler.
Then compare the maintenance schedule. Most products fit monthly cleaning, but ACTIVE Pet Owners also describes twice-monthly use.
Renuv provides six tablets, while Green Gobbler provides 28 and True Fresh provides 25.
Finally, decide whether you want scent. ACTIVE Descaler and Renuv are unscented.
ECO-GALS and Tide provide a fresh scented finish, while Lemi Shine centers on citric acid rather than perfume.
For high-efficiency models, compare these picks with our guide to the best natural HE washing machine cleaner. If your machine is septic-connected, see the best septic-safe washing machine cleaner guide.
How to use a natural washing machine cleaner
Run the cleaner in an empty washer unless its instructions say otherwise. Tablets generally go in the drum, not the detergent drawer, while powder packets follow their own directions.
An empty drum lets the cleaner circulate through the tub, pump and filter areas. Laundry can absorb cleaning action and trap residue.
Choose the Clean Washer cycle when available. Otherwise use the hot or normal cycle specified, then wipe residue from reachable surfaces.
A full cycle matters because time release and effervescent formulas keep working through the wash. Stopping early may leave residue behind.
Do not combine the cleaner with laundry, detergent or other chemicals unless the instructions allow it.
Clean the door seal, dispenser and drain areas separately. Those spots often hold damp material a tablet may not fully remove.
A cleaner helps with maintenance but does not replace repairs. Persistent leaks, drainage problems or strong odors may need attention beyond a tablet.
Front load owners should check door seal folds. Top load owners should check the tub edge and filter area when accessible.
Between cleans, leave the door ajar so the drum can dry. Store tablets or packets dry with the package closed, and run the cleaner on the same day each month.
Which natural washing machine cleaner should you buy?
Pick Affresh Washing Machine Cleaner if you want the simplest monthly routine for a broad range of washers. Its 12 tablets, septic safe formula and front load, top load and HE compatibility make it an easy general choice.
Choose ACTIVE Washing Machine Cleaner for Pet Owners when pet hair, urine or organic residue is the main concern. Its enzyme blend and twice monthly option suit homes where pet residue builds up faster.
Choose ACTIVE Washing Machine Cleaner Descaler 24 Pack for hard water buildup, Lemi Shine Washing Machine Cleaner Plus Machine Wipes for citric acid and Green Gobbler Premium Washing Machine Cleaner for pipes, drains and hoses.
If hard water leaves visible mineral deposits, a descaler or citric acid formula may beat a general tablet. If odor seems to come from the drain path, a system focused cleaner may help more.
If septic compatibility decides your pick, compare details in our best septic safe washing machine cleaner guide. For loading habits that reduce residue, see How to Load a Washing Machine Without Overloading It.
For a broader explanation of the wash process, read How Does a Washing Machine Clean Clothes? A Simple Guide.
Front load owners can also compare best front load washer cleaning tablets.
Scent can decide the final pick too. Unscented ACTIVE Descaler and Renuv suit buyers who prefer no added fragrance, while ECO-GALS and Tide suit buyers who want a fresh scented finish.
Tablets are pre measured and simple to store, while Tide powder packets suit powder buyers. Supply size should fit your schedule, as a 24 or 25 tablet pack can support a year of monthly care.
