This is so easy to do- but somewhat time consuming.
(Parts=cups, but you can use whatever measurements you like.)
-2 parts Borax
-3 parts Washing soda
-1 bar All-natural soap; I use Kirks Coco-Castille
-Essential oil: I use Lemon, but lavender would be nice, too!
The first thing you need to do is put on your favorite TV show!
Grate the soap- this takes the longest. Then add the washing soda and borax to the grated soap, along with the essential oil. Mix well.
You only need 2 tbsp per load.
