First, I gathered up my supplies:
- Washing Soda
- 1 bar castile soap (or olive soap)
- Tea tree oil (or essential oil of choice)
- Food processor & measuring cup
Next, I set up in a well-ventilated area (carport) and put on a mask because there are going to be particles flying around. Safety first!
I probably could have/should have worn gloves because the washing soda can irritate your skin, but I didn't and I survived. Just wash up thoroughly afterward.
Using the grating disc, grate the bar of soap. Then replace the grating disc with the S-blade. Add in 1 cup of washing soda and 1 cup of borax. Turn it on and let it process until it's a fine powder.
While the processor is doing its business, I like to add some essential oil. You can add anything that smells good (sometimes I do lavender), but I like tea tree oil because it freshens my laundry machine and it has anti-fungal properties. Add about 10 drops of oil and let it fully incorporate.
Use about 2 Tablespoons per large load
