You asked for it and I'm happy to share. This is the recipe for the laundry detergent we make to give away in Bonaire United Methodist Church's food pantry. It is really simple and inexpensive to make if you have four ingredients, a 5 gallon bucket with a lid and empty detergent bottles to pour it into.
1 3.5 ounce bar of Ivory soap, grated
1 cup Borax (found on the laundry aisle)
1 cup Washing Soda (found on the laundry aisle)
1 cup Armand Hammar dry laundry detergent (*optional- for a light scent)
Write SHAKE WELL on the neck of each bottle with a Sharpie.
The cost to make five gallons is less than $2.00
Grate the bar of soap.
Using a cheese grater, grate the bar of Ivory Soap. I usually buy the small Ivory soap bars in the 10 pack. That way, I have plenty when it is time to make soap. One bar goes into making five gallons of laundry detergent.
Measure out one cup of each of the dry ingredients.
Bring a pot of water to a rolling boil.
Get a big pot of water and bring it to a rolling boil. Turn off heat (or the soap will boil over and you will be mad). Dissolve the grated soap first and then add the 3 cups of dry ingredients. Stir until it is all dissolved.
Pour into bucket.
Fill a five gallon bucket with warm/hot tap water about 3/4 full. Add the soap mixture and stir. When making 30-40 bottles, you can go ahead and stir the mixture and pour it up into bottles. Just make sure that you shake the bottles well before giving it out. If you are making only a few bottles, cover the bucket with the lid. The next day, the detergent will have a jello consistency. Whisk it up and then pour into bottles.
*Pourable bottles work better than the bottles with the dispenser on the end because this detergent is thicker than commercial detergent.
