I've been using homemade laundry detergent for years. I first tried a dry version (1 bar Dr. Bronners, 1C borax, 1C washing soda) and I loved it. Over the summer I made the liquid version, and it was much more of a pain in the ass to make, to use, and to store, so I went back to dry. But this last batch I did an experiment and used 2C each borax/washing soda to 1 bar Dr. Bronners, and it works just as well as the 1C proportion. The Dr. Bronners bar soap is the most expensive part, so anything that pushes it a little further is good with me. I use 1TB for regular loads, 2TB for heavily soiled stuff. Works like a charm, and even whitens the whites!
