1 cup of Borax
1 cup Super Washing Soda (NOT Baking Soda!)
1 bar of Castile Soap, grated (You can use any vegan bar soap grated.) I love the tea tree oil castile version which makes everything smell clean and fresh.
Mix all ingredients in a large plastic container with lid. Use 2 to 4 tablespoons depending on the how large/soiled the load of laundry is. Make sure to shake the container everytime you use it as contents settle. You can also use white vinegar as a wonderful softner.
