I have never tried Borax in the dish washer. 20 mule team borax is a wonderful cleaner and deodorizer, so I make a laundry detergent using borax and washing soda, granny's lye soap or castile soap.
20 mule team borax is made in the USA. My castile soap is made in Kentucky, lye soap is made locally. Where ever possible I try to support USA products.
Borax is also good for termite control.
I’ll have to try that. Right now I use arm and hammer and add bleach when I do my sheets and towels.
