📦 Ingredients — For 2.5 Gallons
What You'll Need
- 🧼 ½ bar Fels Naptha soap — grated (or use Zote, Ivory, or Castile soap)
- 💧 2 cups water — for melting the soap
- 💧 Hot water — to fill container halfway
- 🧂 ½ cup washing soda — sodium carbonate (NOT baking soda!)
- 🧂 ¼ cup borax — 20 Mule Team Borax
- 🌿 Essential oil (optional) — lavender, lemon, or citrus
Equipment Needed
- 🪣 2.5-gallon bucket — with lid
- 🍲 Large pot or microwave-safe bowl — for melting the soap
- 🧀 Cheese grater — for grating the soap
- 🥄 Long-handled spoon — for stirring
- 🧴 Storage containers — old detergent jugs or pump bottles
💡 Pro tip: "You can find Fels Naptha, washing soda, and borax in the laundry aisle of most grocery stores. They're inexpensive and last for many batches."
📝 Step-by-Step Instructions
Step 1 — Grate and Melt the Soap
- Grate half a bar of Fels Naptha soap using a cheese grater.
- Melt the grated soap in 2 cups of water. You can use a double boiler or simply heat it in a microwave-safe bowl.
- Stir until the soap is completely dissolved.
Step 2 — Prepare the Container
- Fill your 2.5-gallon container halfway with hot water.
- The hot water helps dissolve the washing soda and borax more effectively.
Step 3 — Add Washing Soda and Borax
- Add ½ cup of washing soda and ¼ cup of borax to the container.
- Stir well to ensure they dissolve completely.
⚠️ Important: "Make sure you're using washing soda (sodium carbonate), not baking soda (sodium bicarbonate). They are completely different and will give different results."
Step 4 — Add the Melted Soap
- Once the soap is fully dissolved, add it to the container.
- Mix thoroughly until all the ingredients are combined.
Step 5 — Top Off with Water
- Top off the container with water until you reach a total volume of 2.5 gallons.
- Ensure that all the ingredients are well incorporated.
Step 6 — Add Essential Oils (Optional)
- If desired, add a few drops of your preferred essential oil — lavender, lemon, or citrus.
- This infuses a delightful fragrance into your laundry detergent.
Step 7 — Let It Set
- Allow the mixture to sit for 24 hours.
- During this time, it may start to gel up, which is completely normal.
- Stir the mixture occasionally to maintain consistency.
Step 8 — Final Mix
- After 24 hours, give the laundry detergent a final thorough mix.
- Ensure all the ingredients are well distributed.
- Transfer to storage containers for easy dispensing.
🧺 How to Use Your Homemade Laundry Detergent

Tips for Best Results

❓ Frequently Asked Questions
❓ How long does a 2.5-gallon batch last?
For a family of 4, a 2.5-gallon batch lasts about 3–6 months depending on how many loads you do.
❓ Can I use this in an HE machine?
Yes — just use 2–3 tablespoons per load instead of ¼ cup. The detergent is low-sudsing and safe for HE machines.
❓ Is this soap safe for sensitive skin?
Yes — this recipe uses simple, gentle ingredients. For sensitive skin, use unscented Ivory soap and skip the essential oils.
❓ Can I use baking soda instead of washing soda?
No — baking soda (sodium bicarbonate) is different from washing soda (sodium carbonate). Washing soda is much more effective for laundry.
❓ Why is my detergent clumping?
Clumping usually happens if the ingredients weren't dissolved completely or if the mixture wasn't stirred enough during the 24-hour setting period.
❓ Can I use this detergent in cold water?
Yes — but it dissolves better in warm or hot water. For cold water washes, dissolve the detergent in a cup of warm water first.
❓ Does this detergent work on stains?
Yes — the combination of soap, washing soda, and borax is very effective on stains. For tough stains, pretreat with a little of the undiluted detergent.
❓ Is this soap septic-safe?
Yes — this soap is safe for septic systems. The ingredients are natural and biodegradable.
❓ Can I use this soap for hand-washing clothes?
Absolutely — just dissolve a small amount in warm water and wash as usual.
❓ What if I can't find Fels Naptha?
You can use Zote, Ivory, Kirk's Castile, or any pure soap bar. Just make sure it doesn't contain moisturizers or additives.
❓ Can I make a smaller batch?
Yes — just scale down the recipe. For 1 gallon: use ¼ bar soap, 1 cup washing soda, ¼ cup borax, and 4 cups water.
❓ How do I store the detergent long-term?
Keep it in a sealed bucket or bottles in a cool, dry place. It will last for 6–12 months.
