There is another recipe here with the same ingredients but different amounts and sort of harder to mix. I did not want to post another but as you can see this mix gets great reviews. This one is in several places on the internet with even Consumer Reports giving it thumbs up. After I tried it, several times, I was so sold on it that I had a spattered, torn up, piece of paper taped to my cupboard door where I kept my cleaning supplies. You will so much like the results on glass for sure. It dries so fast that it does not streak. Easy on the nose, eyes, skin, & smell. How much do you save? Well, I don't know but as it works so well who cares?
