Well, sort of. I used the recipe from frugalveggiemama for cheaper dishwasher detergent.
I had bought Seventh Generation powdered dishwasher detergent (for $4.29). Put in one cup of that, one cup of borax, one cup of washing soda. Did a test load and it worked great. Didn't put in any rinse agent, like vinegar, but the glases came out squeaky clean! So, it's a winner.
As we use up what cleaning products we have, I'll be substituting cheaper and non-toxic products.
Now I just have to find out if Bi-o-kleen hand dishwashing liquid can be cut with water. Trying to do that with softsoap did not work well. I'd like to use this stuff for handsoap too.
