How to Strip Laundry in 4 Steps, and the 1 Mistake That Undoes the Soak (Recipe Included)

how to strip laundry in a bathtub with white towels soaking in hot water

Short Answer: Soak 4 to 5 Hours, Then Rinse Clean

How to strip laundry: soak clean, hot-water-safe towels or sheets for 4 to 5 hours in a tub with 1/4 cup Borax, 1/4 cup washing soda, and 1/2 cup powdered detergent, then rinse with no detergent. The powders pull out residue, not stains, which is why the soak only helps fabric that feels stiff or smells stale.

The classic bath needs three powders, and I’d start with Arm & Hammer Super Washing Soda, Harris Borax, and a powdered detergent such as Arm & Hammer Powder Laundry Detergent in Alpine Clean. All three ship from Amazon, and all were in stock when I checked the listings on October 25, 2026. The tub recipe uses 1/4 cup of the first two and 1/2 cup of the third.

This guide covers how to strip laundry, then adds what the manufacturer pages leave out. That means where they disagree, how to scale the amounts for a bucket, and a plain test for whether the soak worked.

Everything here comes from manufacturer and lab pages I read in full, Amazon listing details I checked on October 25, 2026, and my own use where I say so.

The 4 steps take about six hours, most of it waiting. The 1 mistake that undoes them happens afterward, so it gets its own section.

How to Strip Laundry: The 4 Supplies at a Glance

What Is Laundry Stripping, and Do You Need It?

What is laundry stripping? It’s a hot soak in Borax, washing soda, and powdered detergent that pulls detergent, softener, hard water minerals, and body oils out of laundry that already looks clean, according to Arm & Hammer. It’s not bleach, and it’s not a stain remover.

Maytag calls it an aggressive method and says a properly done wash shouldn’t need it. Murky water proves less than it looks like, because Maytag says much of what floats is leftover detergent and softener, and Consumer Reports says the water can turn gray, black, or the color of the fabric.

What is laundry stripping going to fix for you? Match your symptom to a first move before you commit six hours. The table is my synthesis of the sources, not a published protocol.

SymptomLikely cause per the sourcesFirst moveStrip if
Stiff or sticky towelsDetergent or softener residueDetergent-free rinse and spin, then cut the dose. Our guide on how to make towels soft again covers the wash routineThey are still stiff afterward
Towels that shed waterA film from softener or dryer sheetsStop softener on towels and add an extra rinseAbsorbency hasn’t returned

Dingy white sheetsBuildup, since stripping is not a bleachWash with the right detergent doseThey still look dull afterward
Visible stainsNot a residue problemPretreat and washNever, since stripping won’t lift them

For stains, a pretreat does the job. Our roundup of the best stain remover for set-in stains covers that step, and a powder like OxiClean Versatile belongs before the soak, not in it.

The Laundry Stripping Recipe: Amounts by Source

Every laundry stripping recipe I found uses Borax, an alkaline powder, and powdered detergent. Arm & Hammer, Tide, and Maytag all land on 1/4 cup, 1/4 cup, and 1/2 cup for a standard tub. Search for a strip laundry recipe or a stripping laundry recipe and you land on the same three powders, so the amounts barely change with how to strip laundry advice from any source.

how to strip laundry recipe amounts per tub from Arm and Hammer, Tide, Maytag, and Heritage Park
Recipe amounts for how to strip laundry, per standard tub, across four published sources.
SourceBoraxAlkaline powderPowdered detergentSoak
Arm & Hammer1/4 cup1/4 cup washing soda1/2 cup4 to 5 hours, until the water cools
Tide1/4 cup1/4 cup baking soda1/2 cup4 to 5 hours
Maytag1/4 cup1/4 cup washing soda1/2 cupOvernight
Heritage Park1/4 cup1/4 cup washing soda1/4 cup4 to 6 hours

Heritage Park, a detergent maker, is the outlier at 1/4 cup of detergent, which halves the detergent share. Tide swaps in baking soda, and everyone else uses washing soda.

The best laundry stripping recipe for a first bath, in my view, is the 1:1:2 version with washing soda, since Arm & Hammer and Maytag both use it and Tide matches the amounts with baking soda. No source I read compares the two soda powders head to head, so treat Tide’s laundry stripping with baking soda as an option, not an upgrade. Our baking soda vs washing soda comparison explains why they aren’t interchangeable, and our baking soda in laundry guide covers the milder one.

Use powdered detergent only, such as Arm & Hammer Powder Laundry Detergent. Arm & Hammer says liquid detergent won’t work with the other powders, and its page says not to use a powder that contains bleach.

That warning sits oddly next to Arm & Hammer’s own recipe, which names its Plus OxiClean powder detergent. I read the warning as aimed at chlorine bleach, but that is my reading, so check the label of whatever powder you pour in.

How Strong Is the Laundry Stripping Recipe? A Reality Check

The Super Washing Soda listing directs 1/2 cup at the start of a wash cycle, added with detergent. The strip bath uses 1/4 cup, so it holds half the washing soda of a normal wash-cycle dose, spread through a whole tub of water.

My read is that what the bath adds is hot water and hours, not extra chemical. I wouldn’t double the powder, since Maytag already calls the method harsh on fabrics and no source I read suggests more.

Scaling Down for a Bucket or Sink

Tide says a bucket needs different amounts than a tub but gives no numbers. I scaled the tub recipe by water volume, assuming a half-to-three-quarters-full tub holds about 25 gallons (my estimate), so a 5-gallon bucket gets about one-fifth.

ContainerBoraxWashing sodaPowdered detergentWhere the numbers come from
Standard tub, half to three-quarters full1/4 cup1/4 cup1/2 cupArm & Hammer and Maytag
5-gallon bucketAbout 1 tablespoonAbout 1 tablespoonAbout 2 tablespoonsCalculated from the tub recipe and a 25-gallon estimate, not a manufacturer figure

Dissolve the powders in a jug of hot water first, then pour the jug into the bucket. The laundry stripping method doesn’t change, so how to strip your laundry in a bucket or sink follows the same four steps.

How to Strip Laundry: 4 Essential Steps

These laundry stripping instructions combine Arm & Hammer‘s and Tide‘s steps with the safety details from Consumer Reports. Tide counts 4 to 5 hours for the soak and another 1 to 2 hours for rinsing and drying.

how to strip laundry in 4 essential steps: wash, dissolve the powders, soak 4 to 5 hours, rinse and dry
The 4 essential steps for how to strip laundry, from Arm and Hammer and Tide.

1. Wash First, Then Check Every Label

How to do laundry stripping starts with a normal wash. Both Arm & Hammer and Tide say to wash the items first, so the bath has residue to remove and not fresh dirt. Check every care label for hot water, and sort lights and darks into separate batches.

Clean the tub too. Tide says stripping in a dirty basin defeats the purpose, and our guide to the best all purpose cleaner covers what to use on a tub, followed by a thorough rinse.

2. Dissolve the Powders Before the Laundry Goes In

Fill the tub half to three-quarters full with the hottest water the labels allow. Put on gloves first, because Consumer Reports’ Rich Handel recommends gloves and a mask for washing soda, which he calls potentially caustic. Pour close to the water to keep the dust down.

Add 1/4 cup Borax, 1/4 cup washing soda, and 1/2 cup powdered detergent, then stir with a long handle until nothing sits on the surface. Arm & Hammer and Tide both have you stir the powders in first and add the laundry afterward.

3. Soak Until the Water Cools

Add the laundry, push it under, and leave room for water to move. Arm & Hammer says to run two batches instead of overloading the tub. Plan on 4 to 5 hours, and stir about once an hour.

how to strip laundry soak times compared across Arm and Hammer, Tide, Heritage Park, and Maytag
Soak times for how to strip laundry, by source. Maytag says overnight and gives no hour figure.

Soak time is where the sources diverge most. Arm & Hammer and Tide stop at 4 to 5 hours, Heritage Park runs to 6, and Maytag says overnight.

My read is to stop when the water has cooled, roughly 4 to 5 hours, because Arm & Hammer ties the soak to that point. I found no source showing that hours past it add cleaning. Hot tub water is a scald risk, so keep kids and pets out of the bathroom until the tub is drained.

4. Rinse With No Detergent, Then Dry

Wring out the items and put them straight into the washer. Run a rinse cycle, using the double-rinse setting if there is one, and add no detergent or softener. Then tumble dry with no dryer sheets, and wipe out the tub so nothing stains the next bath.

Maytag’s version differs. It leaves items in overnight, drains the tub, and has you rinse well by hand. Arm & Hammer gives a reason for the washer rinse, which is to carry the loosened residue away so it isn’t redeposited on your laundry, so I’d follow its version.

Towel Stripping: How to Strip Towels and Sheets Without Ruining Them

Towel stripping is where the method makes the most sense. Arm & Hammer says thicker, denser fabrics and natural fibers like cotton hold the most residue, and Maytag points to light-colored, bulky towels and sheets.

For laundry stripping towels, and for how to strip towels in general, the rule is batching. Keep them in their own batch, because Arm & Hammer says towels and sheets have different textures and do better with like items. Bath towels, hand towels, washcloths, and beach towels can share a tub as long as water still moves around them.

How to strip sheets is mostly a volume problem, since sheets float and tangle. Stripping sheets means pushing them under every hour and using two batches instead of one packed tub. Towel stripping follows the same clock, so give each fabric its own batch.

ItemStrip it?What to check
Light or white cotton bath towelsYesBest candidates per Arm & Hammer and Maytag
Cotton sheets and pillowcasesYes, in a separate batchKeep them apart from towels
Colored or dark towelsTest first or skipMaytag says dye can run in hot water, and Heritage Park advises against dark or bright items
Bath matsOnly if the label allows hot waterArm & Hammer lists mats, so check the backing material
PillowsCheck the care labelArm & Hammer lists pillows with a label check
Blankets and duvet coversCheck the care labelArm & Hammer lists both, so match the tub size to the item

How to strip pillows and how to strip a comforter follow the same recipe, but the care label decides. A bulky comforter can need a bathtub to itself.

Hard water laundry collects residue faster. Arm & Hammer cites a figure of 85% of US households having hard water, so the dose you use afterward matters as much as how to strip laundry in the first place. Our guide to how to make towels soft again covers the wash-routine fixes.

Which Fabrics Can You Strip? A Fabric-by-Fabric Check

Use this table when a label or a source leaves you unsure how to strip laundry that isn’t plain cotton. It lists the stricter verdict wherever sources disagree. Towel stripping and sheet stripping on light cotton are the only uses where every source I read agrees.

FabricVerdictWhy
Light cotton towels and sheetsYesBulky and heat tolerant, and the first items Arm & Hammer and Maytag name
Dark or bright colorsSkipMaytag says hot water can run dye. Arm & Hammer says any color works since there is no bleach, so follow the stricter source
Spandex and workout clothesSkipMaytag says spandex degrades in the solution’s pH, and Heritage Park advises against athletic wear and elastic. Arm & Hammer lists workout clothes, so follow the stricter source
WoolNoMaytag says it loses its protective lanolin
Silk and laceNoHeritage Park lists both as do-not-strip
Dry-clean-only itemsNoHeritage Park lists them as do-not-strip
Anything labeled cold water onlyNoMaytag says the soak may damage, shrink, or distort it

Two trade-offs sit behind the verdicts. Consumer Reports’ Rich Handel says the soak can remove dye and damage fabrics vulnerable to heat and high pH, and Maytag says it can leach out naturally occurring oils. That is the reason for the few-times-a-year limit, and the reason to skip stripping on anything you can’t replace.

Skip the 1 Mistake That Undoes the Soak

Learning how to strip laundry is the easy half. The 1 mistake is going back to the same routine. If too much detergent or softener built the residue, the next normal wash rebuilds it, and the soak only reset the clock.

Consumer Reports names four causes of residue, and three of them are habits you control. Change them on the first wash after the soak.

What is laundry stripping without that change? A reset that lasts a season.

CauseFixSource
Too much detergentStart at the lowest recommended dose on the cup for a medium load, and raise it slightly only if clothes aren’t cleanConsumer Reports
Fabric softenerSkimp or skip it, and never use it on towels or workout clothesConsumer Reports, Maytag
Detergent and softener togetherDon’t add both at once, since Maytag says they can form a sludge. Softener belongs in the final rinseMaytag
Incomplete rinsingAdd an extra rinse to the cycleMaytag, Consumer Reports
Overstuffed washerRun smaller loads so garments can agitate and rinseConsumer Reports, Maytag
Hard waterExpect residue to return faster, since Arm & Hammer cites 85% of US householdsArm & Hammer

Skip that table and you’ll be stripping again within a season. Maytag says no more than a few times a year, and Heritage Park says six-month intervals at minimum, though its own comparison table lists every 3 to 6 months. My rule is to strip only when the symptom check says so, and no more than twice a year.

If you’re changing detergents to cut the dose, our Seventh Generation laundry detergent review checks the dose per load on three formats, and our eco friendly laundry detergent guide compares formats side by side.

Keep vinegar out of the strip bath too. Vinegar is an acid and washing soda is alkaline, so the two cancel each other out and you’d waste the powder. Two Hometalk commenters recommend vinegar in the final rinse for dingy towels, and if you try it, give it its own cycle and never the tub.

How to Strip Laundry With Borax (and Without It)

How to strip laundry with borax starts with why it’s there. In laundry stripping with borax, the powder is the third ingredient in every recipe I read, and Harris Borax is the one I’d link. Of the four borax listings I checked on October 25, 2026, it was the only one that passed, since the main 20 Mule Team 65 oz listing had no Buy Box and the other two 20 Mule Team listings shipped from third-party sellers.

The Harris listing sells it as a hard-water laundry booster and says to mix 1 scoop (2 oz) per load, with a scoop included in a resealable bag. I’ve used Harris Borax for over a year. In my regular loads it makes my detergent work much better and gets rid of bad odors.

Calculated from the listing, 24 oz at 2 oz a scoop is 12 scoops, not the 20 loads the listing states, so I’d plan on 12. I couldn’t read Harris’s printed label on its Amazon page, so I’m not quoting a dose or cautions from it.

Read the cautions on the bag, keep it away from kids and pets, and wear gloves and a mask as Consumer Reports advises for washing soda. If anyone swallows any of these powders, call Poison Help at 1-800-222-1222.

How to strip laundry without borax is the top follow-up question, and I couldn’t find a manufacturer-published borax-free recipe. Tide’s recipe swaps baking soda for washing soda but keeps the borax. The steps for how to strip clothes with borax match the towel steps, once you’ve checked every label.

If you’d rather skip borax entirely, the sourced alternatives are Maytag’s long hot soak in the washer with regular detergent followed by a rinse cycle, Consumer Reports’ detergent-free rinse and spin cycle, and Heritage Park’s vinegar wash then baking soda wash in two separate cycles with no detergent.

Laundry Stripping vs a Detergent-Free Rinse: Which First?

If you’d rather skip learning how to strip laundry altogether, Consumer Reports’ Rich Handel has a shortcut. He says a rinse and spin cycle in a front-loader, or a deep soak-and-spin in a top-loader, both without detergent, gets better results with less work, though you won’t see the residue drain off.

MethodEffortBest forSource
Bathtub laundry stripping4 to 5 hours plus cleanupStubborn buildup on light cottonArm & Hammer, Tide
Detergent-free rinse and spin, or soak-and-spinOne machine cycleFirst fix for ordinary residueConsumer Reports
Long hot soak in the washer with regular detergent, then a rinseOne long cycle plus a rinseA gentler extra soakMaytag
Vinegar wash, then baking soda wash, in separate cyclesTwo wash cyclesRegular towel maintenanceHeritage Park
Lower detergent dose from now onFreePreventing the problemConsumer Reports, Maytag

My order is the rinse and spin cycle first, then a strip only if the towels are still stiff or stale afterward, with stains handled separately. If you want how to deep clean towels without the tub, that cycle is where to start.

How to Tell the Soak Worked (Without Trusting the Water)

Once you know how to strip laundry, judge the result on the fabric, not the tub. Skip the laundry stripping before and after photos, since dye, lint, and leftover detergent all cloud the water and its color says little about whether the towels improved.

Dry the batch completely, then compare a stripped towel with an unstripped one from the same set. Drop a little water on each and see which pulls it in faster, since absorbency is the problem stripping is supposed to fix. That test is my method, not a published one.

Feel and smell answer the other complaints. A towel that is still stiff or musty after a full dry probably means residue wasn’t the cause, so look at hard water and your dose before you repeat the soak. If the smell keeps returning, check the washer, and our front load washer mold guide covers the gasket and drum.

Our post on why towels smell after washing covers the drying side.

The 4 Supplies for How to Strip Laundry, Reviewed

All four supplies passed my live Amazon check on October 25, 2026. Each was in stock, shipped by Amazon.com or from Amazon’s warehouse, and carried a monthly purchase badge. Specs below are as listed on the pages I read.

Before you add any of them to your cart, search the listing’s reviews for the words “dissolve” and “residue,” since those two matter most in a strip bath.

1. Arm & Hammer Super Washing Soda: The Alkaline Backbone

SpecDetail
Active ingredientSodium carbonate
Size55 oz box (pack of 1 tile)
Listing claimsFragrance-free and phosphate-free
Listing directions1/2 cup with liquid or powder detergent at the start of the wash cycle
SellerAmazon.com

Washing soda supplies the alkalinity in the bath, and it is the reason for the gloves. Our baking soda vs washing soda comparison covers how far apart it sits from baking soda. I’ve used Super Washing Soda as a laundry booster for more than three years, and I notice a softer-water effect in my loads.

Best for anyone making the 1:1:2 bath who wants the washing soda that Arm & Hammer’s own recipe names.

Skip it if you want a fragranced or oxygen-boosted product, since the listing describes a single ingredient, sodium carbonate, and calls it fragrance free.

The link goes to the 55 oz box in a pack of 1. A pack of 2 sits on the same listing, so check the tile before adding to cart.


2. Harris Borax Powder: The Water Conditioner

SpecDetail
Size24 oz (1.5 lb) bag, unscented
Listing dose1 scoop (2 oz) per load, scoop included
Listing claimCleans up to 20 loads (calculated: 24 oz divided by 2 oz is 12 scoops)
PackagingResealable bag
SellerSold by PF Harris, ships from Amazon

Borax is the third powder in every recipe I read, and this listing sells it as a hard-water laundry booster. I’ve used it for over a year, and in my regular loads it makes my detergent work much better and gets rid of bad odors. It isn’t Amazon-sold, so I’d check the seller line at checkout.

Best for a first strip if you have no borax on the shelf.

Skip it if you want the biggest bag, since this tile is the 24 oz size and a 160 oz tile sits on the same listing.

The link goes to the 24 oz (1.5 lb) unscented bag. The 160 oz and 3-pack tiles sit on the same listing, so check the tile before adding to cart.


3. Arm & Hammer Powder Laundry Detergent, Alpine Clean: The Powder

SpecDetail
Size9.56 lb (153 oz), 155 loads as listed
ScentAlpine Clean by default, with Clean Burst and Fragrance Free options on the listing
Listing claimsActivated baking soda to help eliminate odors, tough on stains
SellerAmazon.com

Arm & Hammer’s recipe names its Plus OxiClean powder, and I couldn’t confirm this Alpine Clean listing is the same product. Check your box against the no-bleach warning before you pour.

I’ve used this powder for over a year on everyday mixed loads of work clothes or scrubs and whites. It smells fresh and light, handles sweat and outdoor odors, and costs much less per load than liquid detergents. That is everyday washing, not a strip bath.

Best for a first-time stripper without a powdered detergent on hand.

Skip it if you avoid fragrance, since the default scent is Alpine Clean, though a Fragrance Free option sits on the same listing.

The link goes to the 153 oz (9.56 lb) Alpine Clean tile. Clean Burst and Fragrance Free options and a 3-pack sit on the same listing, so check the tile before adding to cart.


4. OxiClean Versatile Stain Remover Powder: The Optional Pretreat

SpecDetail
Size5 lb (80 oz) tub
Listing claimsOxygen-powered, color safe, chlorine free, septic-tank safe
Listing usePresoak stain remover and in-wash laundry booster, used with detergent
SellerAmazon.com

OxiClean isn’t part of the classic bath, since none of the recipes I read include it. I’d use it before the strip to lift stains, then wash and rinse the items, because Arm & Hammer and Maytag both say stripping won’t remove stains.

Best for towels that look dingy because of stains, not residue.

Skip it for the strip bath itself, since the listing sells it as a stain remover and presoak.

The link goes to the 5 lb (80 oz) tub. Check the tile before adding to cart in case other sizes sit on the listing.

Which Supplies Do You Need?

You need three of these four to learn how to strip laundry the classic way, and the fourth is optional.

Arm & Hammer Super Washing Soda

  • Buy it if you’re making the 1:1:2 bath.
  • Wear gloves whenever you handle the dry powder or the solution.
  • Skip it for anything you wouldn’t soak in hot water.

Harris Borax Powder

  • Buy it if borax is missing from your shelf.
  • Skip it if you can’t store it out of reach of kids and pets.

Arm & Hammer Powder Laundry Detergent

  • Buy it if you don’t own a powdered detergent without chlorine bleach.
  • Skip it if you avoid fragrance.
  • Check the label against Arm & Hammer’s bleach warning before you pour.

OxiClean Versatile Stain Remover Powder

  • Buy it if stains are the reason the towels look dingy.
  • Skip it for the strip bath itself.

Frequently Asked Questions

Does laundry stripping work?

Yes on residue from detergent, softener, hard water minerals, and body oils, but not on stains, and Consumer Reports’ Rich Handel says a detergent-free rinse and spin cycle can do the job with less work.

  • It works on stiff, sticky towels and sheets that hold a film of detergent or softener.
  • It doesn’t touch stains, and it isn’t a bleach.
  • Judge it by absorbency, not by how dark the water turns.

How often should you strip laundry?

No more than a few times a year, and only on items that show buildup, according to Maytag, which calls the method harsh on fabrics.

  • Signs it’s due include sticky or stiff towels, lost absorbency, and a stale smell after washing.
  • Prevention beats repeats, so use the lowest recommended detergent dose and add an extra rinse.
  • Sources disagree on the interval, and Heritage Park says six months at minimum.

Can you strip laundry in the washing machine?

Not with the stripping powders, because Maytag says a stripping solution could damage your washer.

  • Use a long soak with regular detergent plus a rinse cycle, which is Maytag’s gentler option.
  • Front-loaders can run a rinse and spin cycle with no detergent, and top-loaders can run a deep soak-and-spin.
  • Keep the powders in the tub or bucket, where you control the water and the rinse.

One Hometalk commenter, Joyce, asked the obvious question, “Why not just soak the laundry in the washing machine??” Maytag’s answer is the appliance risk.

Final Verdict

If you strip at all, here is how to strip laundry safely. Use the 1:1:2 recipe (1/4 cup Borax, 1/4 cup washing soda, 1/2 cup powdered detergent) on light cotton towels or sheets, soak until the water cools, and rinse with no detergent. Run a detergent-free rinse and spin cycle first, because Consumer Reports’ test engineer says it gets better results with less work.

Then skip the 1 mistake. Go back to the lowest detergent dose, no softener on towels, and an extra rinse, or the residue returns.

For more guides, browse our laundry care guides, read how I research every review, or see the types of cleaning products we cover. Skip spandex, wool, silk, dark colors, and cold-water-only items, and cap any strip at a few times a year.
