Grate one bar of soap. I used Dr. Bronner's lavender scent, but a cheaper alternative would be Zote or Fels-Naptha which were both available in my local Walmart and grocery store.
Then I added one cup of Arm and Hammer Washing Powder.
And one cup of Borax. Sorry I don't have the box, this is something I've had in the cupboard for awhile.
And here is what we ended up with.
I'm using one tablespoon per load for a regular load in an HE front loader. The first load seems clean and it was bath towels and socks. I have a cold load running now so we'll see if it dissolves and works well in cold water. I'll update in an hour or so :)
If you prefer a liquid detergent you can use the same ingredients and add water. I have enough supplies to try this too so I may add photos when I get to it :)
- Grate one bar of soap with cheese grater or food processor.
- Put grated soap in pan with 2 quarts water and gradually heat, stirring constantly until soap is completely dissolved.
- Put 4.5 gallons of really hot tap water in a 5-gallon bucket (available for free in bakeries at grocery stores, just ask them) and stir in 1 cup of borax and 1 cup of Washing Soda until completely dissolved.
- Pour soap mixture from pan into 5-gallon bucket. Stir well.
- Cover and leave overnight.
- Shake or stir until smooth and pour into gallon jugs or other containers.
- Use 1/2 to 1 cup per load.
