A week ago, I tried a homemade dishwasher detergent recipe.
Unfortunately, it was not as successful as I had hoped it would be. Although it does an okay job on dishes that are not too dirty to start with, it does Not do a good job (for me, with my washer and water conditions) on things like my glass casserole dishes and my pots and pans. It just doesn't cut it. And, it seems to leave a film on the glassware, even when I use a rinse aid like Jet Dry (the vinegar rinse aid was also a fail).
So, if I'm willing to put in a lot of elbow grease to start with, the detergent will clean well enough. It's just not good for me.
Maybe I'll try another recipe, though.
The recipe I used (with which others have reported great success):
1 cup Borax
1 cup Washing soda
1/2 cup citric acid
1/2 cup kosher salt
