I confess - I tried to make my own dish detergent. And then I kept trying it, thinking it would miraculously start working better. And you know what, it didn't! The glasses never did rinse clean. And yes fellow frugalites, I did try vinegar as a rinse aid. It just did not work for me.
So instead I am back using regular detergent, but way less per wash than ever before. I started pouring it into a plastic tub and scooping it out with a measuring spoon instead of pouring random amounts into the washer each time it ran. Then, this week I had an epiphany, and switched to a measuring spoon half the size as the one I was using and.... it still works great!
So there is my frugal tip!
