Laundry Stripping Recipe (DIY Deep-Clean Soak)
If your towels come out of the wash technically clean but still stiff, dull, and faintly sour once damp, the problem is usually not dirt. It is buildup: detergent residue, fabric softener coating, body oils, and hard-water minerals, trapped deep in the fibers where a normal wash cannot reach.
Laundry stripping is the reset button: a long, hot soak in borax, washing soda, and powdered detergent that loosens the buildup and pulls it out into the water. The murky, tea-colored bathwater at the end shocks everyone the first time, especially when the laundry went in looking perfectly clean.
It is an old laundromat-era method that went viral again for good reason: a few dollars of basic powders, nothing but a bathtub, and it genuinely revives towels you were about to demote to rags.
Why You’ll Love This Recipe
It works on the laundry that needs it most: towels, bed sheets, pillowcases, and sweaty workout clothes collect the most softener coating and mineral crust, and they respond best to a strip.
The supplies are cheap and keep forever; one box each of borax and washing soda covers many batches. Like our other back-to-basics staple, the homemade playdough recipe, it is a simple formula worth having written down.
There is no scrubbing and no special equipment. The soak does the work; you only stir the tub once an hour.
Ingredients
Supplies for one standard bathtub batch. Washing soda is sodium carbonate, a stronger cousin of baking soda; they are not interchangeable here, and baking soda will not do this job:
- ½ cup (about 120 g) borax
- ½ cup (about 110 g) washing soda (sodium carbonate)
- ¼ cup powdered laundry detergent (such as Tide)
- A bathtub of the hottest tap water available
- Clean-ish laundry: towels, sheets, or workout clothes, already washed
You will also need a long-handled spoon for stirring (not a utensil you cook with), and a way to keep children and pets away from the tub while it soaks.

- Sort and check first: Strip only sturdy cottons and synthetics: towels, sheets, pillowcases, gym clothes. Set aside anything in the safety notes below. With dark or bright items, test one piece first; some dyes are not as fast as they claim.
- Fill the tub: Fill a standard bathtub halfway to two-thirds with the hottest water your tap produces. The laundry needs room to move, not a tight pack.
- Dissolve the powders: Add the borax, washing soda, and detergent while the tub fills, then stir until every grain dissolves. Laundry added before the powders dissolve ends up with white gritty patches.
- Submerge the laundry: Add the laundry and push it under, squeezing out air pockets so every piece is saturated. The water will already cloud slightly; the soak is starting its work.
- Soak 4 to 6 hours: Leave the laundry in for 4 to 6 hours, stirring and agitating well with the spoon roughly every hour, turning pieces over. By the end the water ranges from gray-brown to genuinely alarming, which is normal and is the whole point.
- Drain and squeeze: Drain the tub and squeeze each piece well. The load feels heavy and slippery with loosened residue; that rinses away in the machine.
- Rinse in the machine: Transfer everything to the machine and run a rinse-only cycle, or a full wash with no detergent. Dry as usual. Stripped towels come out noticeably softer and more absorbent, because nothing coats the fibers anymore.
Cooking Tips / Variations
Why it works: hot water opens cotton fibers, washing soda softens the water and frees mineral deposits, borax lifts residue and neutralizes odors, and the detergent grabs the loosened oils so they rinse away instead of settling back.
Safety, read before you strip: do not strip wool, silk, delicates, leather, fragile elastic or prints, or items that bleed dye. Keep powders and the soaking tub away from children and pets. Never add bleach or vinegar; the formula is complete as written, and extras create problems, not extra cleaning.
Smaller batches: half the recipe (¼ cup borax, ¼ cup washing soda, 2 tablespoons detergent) works in a top-loader on its hot soak setting, or in a large bucket for a few towels.
How often: this is a deep reset, not a weekly routine. Every three to four months is plenty, or whenever absorbency drops and the sour smell starts surviving the wash.
Serving or Storage Tips
Store borax and washing soda sealed and clearly labeled in a dry cupboard, out of reach of children and pets. Never store them in food jars or anywhere they could be mistaken for something edible.
The soak water simply goes down the drain; no special disposal needed. Rinse the tub afterward, since the loosened grime leaves a ring.
To keep results longer, wash towels with less detergent than the scoop suggests and skip fabric softener on them entirely. Most of what you stripped out arrived via generous scoops.
Conclusion
Three basic powders, the hottest water in the house, and an afternoon of patience: that is all it takes to pull months of invisible buildup out of your hardest-working laundry.
Strip a load of towels once and check the water at the end. The color of that bath is the most convincing argument the recipe makes, and your towels will dry you properly again.
Laundry Stripping Soak
Ingredients
Method
- Fill a standard bathtub with the hottest tap water and stir in the borax, washing soda and detergent until fully dissolved.
- Submerge the clean laundry completely, pushing out air pockets.
- Soak 4–6 hours, stirring and agitating every hour with a long spoon.
- Drain the tub and squeeze out each piece well.
- Run a rinse-only machine cycle (or a full wash with no detergent), then dry as usual.
Notes
Keep powders and the soaking tub away from children and pets.
Never mix bleach or vinegar into this solution.
Murky water is normal — it is the buildup leaving the fabric.
Half batch: ¼ cup borax, ¼ cup washing soda, 2 tablespoons detergent, for a top-loader soak or large bucket.
