What You’ll Need
Before you start making your DIY laundry detergent powder, gather the ingredients and basic tools below. Most items are inexpensive and easy to find online or at local stores.
Ingredients
These three ingredients do the heavy lifting in any DIY laundry detergent powder. They’re inexpensive, easy to find, and work better together than most people expect.
- Washing Soda
- Borax

Tools and Equipment
You don’t need any special equipment to makehomemade laundry soap powder. These four basic tools are likely already sitting in your kitchen.
| Tool | Purpose |
|---|---|
| Grater or Food Processor | Used to shred the soap into fine pieces. Finer shreds mix better and dissolve more evenly in the wash. |
| Large Mixing Bowl or Bucket | Makes it easier to combine ingredients evenly. A bigger bowl also reduces mess when stirring dry powders together. |
| Measuring Cups | Ensures accurate ingredient ratios. Getting the balance right makes a noticeable difference in how well the detergent cleans. |
| Airtight Storage Container | Keeps the detergent fresh and prevents moisture buildup. A sealed container also makes scooping easier every laundry day. |
How to Make DIY Laundry Detergent Powder (Step-by-Step)
Making your own DIY laundry detergent powder is straightforward. Follow these five steps, and you’ll have a full batch ready in under 15 minutes.
Step 1: Grate the Soap
Use a box grater or food processor to shred your bar soap into fine pieces. Smaller shreds blend better and dissolve faster in the wash.
For the smoothest texture, pulse the grated soap briefly in a food processor before mixing it with the other ingredients.
Step 2: Mix the Dry Ingredients
Combine the grated soap, washing soda, and borax in a large bowl. Stir thoroughly until everything is evenly distributed.
Take a few extra minutes to break up any clumps, as an even mixture helps ensure consistent cleaning power in every load.
Step 3: Blend for a Finer Texture (Optional)
Pour the mixture into a food processor and pulse for 20–30 seconds. This gives you a smoother, more uniform powder that dissolves more easily.
Step 4: Add Essential Oils (Optional)
Drop in 10–15 drops of your preferred essential oil and stir well. Lavender, lemon, and peppermint are popular choices for a clean, fresh scent.
Step 5: Store Properly
Transfer the finished powder into an airtight container and keep it in a cool, dry spot. Label it with the date so you always know how fresh it is.
Tip: To prevent clumping, always store yourDIY laundry detergent powder away from humidity and moisture. Adding a small silica gel packet inside the container helps keep the powder dry.
DIY Laundry Detergent Powder Recipes
Making your ownDIY laundry detergent powder at home is simpler than most people think. Below are three tried-and-tested recipes, pick the one that fits your needs best.
Recipe 1: Classic Homemade Laundry Soap Powder
This is the go-to recipe for most households. It uses basic, budget-friendly ingredients that are easy to find at any grocery store.
Ingredients
These are the core ingredients you’ll need for a standard batch. Most of them cost just a few dollars and last for multiple batches.
- 1 cup washing soda
- 1 cup borax
- 1 bar of soap
- ½ cup baking soda (optional, for extra odor control)
- 10–15 drops essential oil (optional, for fragrance)
Instructions
Follow these steps in order for the best results. The whole process takes under 15 minutes from start to finish.
- Step 1: Grate the bar soap using a box grater or food processor until you get fine, even shreds.
- Step 2: Add the washing soda, borax, and baking soda into a large mixing bowl. Stir until combined.
- Step 3: Mix in the grated soap and stir thoroughly until the texture is uniform throughout.
- Step 4: Pulse the entire mixture in a food processor for 20–30 seconds if you prefer a finer powder.
- Step 5: Add essential oils if using, and give everything one final stir.
- Step 6: Transfer into an airtight container and store in a cool, dry place.
Recipe 2: Sensitive Skin Laundry Powder (Borax-Free)
This recipe skips borax entirely, making it a safer pick for sensitive skin, eczema-prone skin, or washing baby clothes.
Ingredients
All four ingredients in this recipe are gentle and fragrance-free by default. Castile soap is the key swap that makes this formula skin-friendly.
- 1 cup washing soda
- 1 cup baking soda
- 1 bar unscented Castile soap (grated fine)
- ½ cup sea salt (helps soften water naturally)
Instructions
This recipe comes together quickly since Castile soap is softer and easier to grate than other bar soaps. Keep the steps simple and don’t rush the mixing.
- Step 1: Grate the Castile soap into the finest shreds possible — this soap is softer and breaks down quickly.
- Step 2: Combine washing soda, baking soda, and sea salt in a large mixing bowl.
- Step 3: Add the grated soap and stir until fully blended with no visible clumps.
- Step 4: Pulse in a food processor for a smoother texture if preferred.
- Step 5: Store in an airtight container away from moisture and humidity.
Recipe 3: Heavy-Duty Stain-Fighting Powder
This one is built for tough loads — think work clothes, sports gear, or anything with set-in stains. The oxygen bleach addition gives it real cleaning strength.
Ingredients
This recipe has a few more ingredients than the others, but each one serves a specific purpose. The oxygen bleach is what sets it apart from a standard powder.
- 1 cup washing soda
- 1 cup borax
- 1 bar Fels-Naptha soap (grated fine)
- ½ cup oxygen bleach powder (for whitening and stain removal)
- ½ cup baking soda
- 10–15 drops lemon essential oil (optional)
Instructions
Fels-Naptha is a firmer soap, so give yourself a little extra time on the grating step. A food processor makes the whole process much faster and easier.
- Step 1: Grate the Fels-Naptha bar soap as finely as possible, it’s firmer than Castile, so a food processor works best.
- Step 2: Mix washing soda, borax, oxygen bleach powder, and baking soda in a large bowl.
- Step 3: Add the grated soap and stir until the mixture is consistent and even throughout.
- Step 4: Blend in a food processor for 30 seconds for a fine, uniform powder.
- Step 5: Add lemon essential oil if using, stir well, then transfer to an airtight container.
