Here's the recipe.
First, in a medium size bowl, add 1 cup Borax:
And 1 cup Washing Soda:
And 1 ENTIRE bar of Castille soap - grated.
It doesn't hurt to have a handsome husband help with the grating, either. He loves being involved!
Mix all 3 ingredients together and you're done!
Here's the end product. If you are like me, and all your appropriately sized tupperware is holding leftovers in your fridge, just grab a plastic bag.
Use about 1/4 cup per load. This recipe will do about 15-20 loads.
If you have a particularly oily or greasy load of laundry (like I do a few times a week!), just add a drizzle of your regular dishwashing detergent. It will pull out all the grease!
I washed our first load with this detergent and it worked perfectly. Enjoy!
