Fels Naptha, Borax, and Washing Soda.
My daughter makes this liquid laundry soap using fels naptha.
I have made a powdered detergent. I used a castille soap made in Kentucky. The 20 mule team boarx I assume is still made in USA as is the washing soda. Haven’t seen any laundry detergent labeled “made in the USA” though there may still be some.
