DIY Thieves Laundry Detergent... for Less Than $5 A Gallon ...
First add 1/4 cup Thieves® Laundry Soap. I have seen similar recipes done with Castile Soap, but I love the idea of using an actual laundry soap instead (and others have reported that the Castile Soap gets chunky and dispensing becomes difficult). Step 6. Next add 1/8 cup (or 2 Tablespoons) of Thieves® Cleaner.
