How to Make Homemade Laundry Soap
This laundry soap works really well with both traditional top-load washers and high-efficiency front-load washing machines. It has a light, fresh scent that is almost undetectable after the wash cycle. It is very inexpensive to make, and produces 5 gallons of soap for each batch. The one factor to remember is that this is not heavily concentrated soap like you buy in the store.
***One load of clothes requires about ¾ to 1 cup of finished soap depending on the size of the load.
1 Bar – Fels Naptha Laundry Soap Bar
1 Cup – Arm & Hammer Washing Soda (not baking soda)
1 Cup – Borax
- Grate the Fels Naptha bar with a kitchen hand grater. Add to a medium saucepan with about 8 cups of water. Heat and stir until all of the soap has dissolved. (Grating is an important step. Just cutting into pieces will now allow it to dissolve properly.)
- In a 5 gallon plastic bucket, fill with water to half full.
- To the 5 gallon bucket with water, add the washing soda and Borax. Mix with a broom handle or stick until the powders are dissolved.
- Add the hot melted Fels Naptha solution to the 5 gallon bucket and stir until combined.
- Fill the 5 gallon bucket the rest of the way until almost full. Cover.
- Let the soap sit for 24 hours. In this time, it will congeal into a loose gel. (The gel will have an inconsistent texture, this is just fine. You may stir as needed.)
- Store the finished soap in used liquid laundry soap containers or in the 5 gallon bucket, whichever you like.
