onegoodthingbyjillee.com. I made a batch almost 3 months ago, and I just ran out a couple days ago. There were just a few things I wanted to do different this time. Although the detergent worked great, I did not want to use Fels Naptha again as the base soap. I used the trick of microwaving the soap instead of grating, and it ruined my microwave! AND THEN, it took the coating off of the bottom of the pot I used. So, the following is what I did this time around.I have become completely addicted to making home made cleaning products. There are so many reasons people are attracted to the idea of making their own cleaning products- the ingredients are safe, they know what's going in them, it's fun (at least I think so), and it saves money. My favorite reason is they WORK.
