To make it you will need the following:
- Arm & Hammer Super Washing Soda (NOT Baking Soda)
- Fels-Naptha Soap Bar
- Oxy Clean
- 5-gallon bucket with lid
- Some kind of jug to keep the finished laundry liquid soap in
Grate the entire bar of the Fels-Naptha soap.
Put in a pot with 4 cups of hot water. Stir continuously over medium-low heat until all of the soap flakes have dissolved and melted (about 20 minutes).
It should be slightly foamy with no “chunks” or flakes to be found
Add 1 cup of Arm & Hammer Washing Soda and 1/2 cup Borax. Then add 1 1/2 cup of Oxy Clean. Stir.
Fill the rest of the 5-gallon bucket with water until it is full. Stir again.
Cover and let it sit overnight.
When you open the top up the next day, it should have gelled and thickened slightly. Stir again.
Fill the container HALF way with the soap mixture. Fill the other half with water and shake.
You will have a LOT of soap mixture left over. Just keep the lid on the 5 gallon bucket and whenever your jug runs out fill it up again half way with the soap mixture and add water to the other half. I keep the 5 gallon bucket of leftover soap mixture in the garage.
If you do not want a lot of leftover soap mixture try using only half the recipe or even a quarter of the recipe.
