Dr. Bronner’s Pure Castile Soap claims 18 cleaning uses in one bottle. One of those is laundry soap. Want to know how to make your own using only a cup of Dr. Bronner’s per 64 loads? Check it out:

This laundry soap doesn’t create suds, but it doesn’t need to in order to get your laundry clean.

What You Need

  • 1 cup Dr. Bronner’s pure castile liquid soap
  • 1 cup baking soda
  • 2 cups water
  • 1/3 cup salt

Instructions

Warm the water and mix with salt and baking soda until dissolved. Pour into a one-gallon container. Add the Dr. Bronner’s and fill the remainder of the gallon jar with water. Use 1/4 cup of laundry soap per load.

This makes a full gallon of laundry soap, which will last 64 loads.
