- 1 Bar Fels Naptha soap
- 1 Cup Borax
- 1 Cup super washing soda
- Shred the soap with a cheese grater or food processor. (The smaller the pieces, the better; if you pulverize it into a powder, you win)
- Mix all ingredients
Add 1 tablespoon of the laundry soap to the washing machine. I'd also just like to note that even though grating soap sounds strange and impossible, it's really like grating a block of cheese so don't let that scare you off from trying this. Also, you can use any bar of soap you want, but we have found that Fels Naptha works the best.
