Delicate fabrics get dingy fast when you wash them with the wrong soap, and babying them by hand gets old in a hurry. This gentle fabric soap gives you a simple homemade wash for hand-laundering washable delicates without dragging home another specialty bottle you barely use. It also lets you keep a ready-to-pour cleaner in the laundry area, which is one less excuse for that “I’ll wash it later” pile. (That pile never folds itself.)
Making your own costs less than buying a small bottle of delicate-wash detergent. Using current Walmart pricing, one batch made with one bar of Ivory and 1/2 cup borax comes to about $1.75 per batch.
For reference, a 16-ounce bottle of Woolite Delicates at about $5.99 handles 8 loads, or roughly 75 cents per load. This version also gives you direct control over the formula, since you’re mixing only soap, borax, and water instead of buying a pre-scented commercial product.
You’ll need 3 materials for this batch: one bar of grated Ivory soap, boiling water, and borax. The finished soap gets stored in a plastic squeeze or pump container, and you’ll just need a large pan plus something to stir with while the soap dissolves.

Materials You’ll Need
- 1 bar Ivory soap, grated
- 4 cups boiling water
- 1/2 cup borax
- Plastic squeeze or pump container for storage
Tools & Equipment
- Large pan
- Stirring spoon or utensil
- Grater, if the soap bar is not already grated
How to Make Gentle Fabric Soap
- Grate 1 bar of Ivory soap.
- Combine the grated soap and 1/2 cup borax in a large pan.
- Pour 4 cups of boiling water over the mixture.
- Stir until the soap is completely dissolved.
- Let the mixture cool.
- Transfer the cooled soap to a plastic squeeze or pump container and keep it in the laundry area.
How to Use It
Measure out 1/4 cup for each quart of water. Add the items to be washed and agitate them around.
The mixture should produce suds. If it does not, add another squirt.
If your delicate items are heavily soiled, soak them for 1 or 2 hours in the cleaning solution before laundering them. You can pair it with a dedicated Pre-Soak for Delicate Fabrics or follow up with Lavender Linen Water if you like a fresher linen finish.
Customization Ideas
- For washable delicates only: Keep this batch dedicated to hand-washable lightweight items, lingerie, and other delicate washables so it stays where it works best.
- For easy dispensing: Use a squeeze bottle if you want quick extra squirts during washing, or a pump container if you prefer neater portioning near the sink or laundry tub.
- For a fuller delicate-care setup: Pair it with Soft Soap for Delicate Washables or a Gentle Bleach Recipe for specialty fabric care jobs.
Safety Information
Keep this soap out of reach of children and pets, and avoid getting the borax mixture in your eyes or on broken skin. If you’ll be washing several items by hand, rinse your hands well afterward. The CDC notes that borates can irritate the eyes, skin, and respiratory system, so it makes sense to handle the dry borax carefully and avoid breathing dust while you mix the batch. See the CDC guidance here: NIOSH Pocket Guide entry for borates.
This is a laundry soap for washable fabrics. It is not a disinfectant, and it is not meant for personal care use.
Storage
After the mixture cools, store it in a plastic squeeze or pump container and keep it in the laundry area. Label the container clearly so nobody mistakes it for hand soap or lotion.
Estimated Cost
Using recent Walmart pricing, this batch costs about $1.75 in consumable materials. That estimate uses one Ivory bar at about 89 cents from a 10-count pack and 1/2 cup borax at about 86 cents based on a 65-ounce box, so prices will vary by store and package size.

Frequently Asked Questions about Gentle Fabric Soap
This formula is written for hand-washing delicate items. The directions tell you to measure 1/4 cup per quart of water, add the items, and agitate them around, so stick with sink, basin, or tub washing unless you already know your machine’s hand-wash setup well.
Use 1/4 cup of the soap for each quart of water. If the mixture doesn’t produce suds while you’re washing, add another squirt.
Soak the item in the cleaning solution for 1 or 2 hours before laundering it. That extra soak time helps loosen soil without changing the original formula.
Yes. Store it in a plastic squeeze or pump container once it cools. Both options make it easier to dispense in small amounts right where you wash delicates.
The directions specifically call for a plastic squeeze or pump container, which makes practical sense in a laundry area where slippery hands, wet counters, and dropped containers happen more often than we’d like to admit.
This formula doesn’t include any fragrance additions, so the most accurate approach is to leave it as written. If you want scented laundry care, it’s better to add fragrance in a separate linen spray instead of changing the soap itself.
It’s best for delicate washables that need gentler hand-laundering rather than a full regular laundry cycle. Think of the pieces you usually hesitate to toss in with everything else.
The original directions don’t require gloves, but if you have sensitive skin or you’ll be handling the wash water for a while, wearing gloves is a sensible extra step. Borax dust and repeated contact with cleaning mixtures can be irritating for some people.
You can scale it up as long as you keep the same ratio of 1 bar Ivory soap, 4 cups boiling water, and 1/2 cup borax per batch. Just make sure your pan is large enough and use a properly sized plastic storage container.
