1 bar ivory soap
1/2 cup borax
1/2 cup baking soda
1 cup oxiclean free
1/8 tsp tea tree oil (optional) - (you can use any other essential oil of choice)
Grate the soap into a food processor, then add everything else and let the chopping blades to the rest. It took me about 5 minutes. Each load takes about 2 Tbsp.
Borax is like 2.68 a box (and that will last me a long time)
Baking soda we all know is super cheap.
The Oxiclean Free cost about 5 bucks for a bucket and the tea tree oil I just had.
Cost effective, environmentally conscious and works great so far!
