Add a tbsp to dishwasher and cut amount of soap in half. Best clean ever. Clear glasses. Also seems to eliminate the crud that sticks to dishes. Can also use baking soda. Now I use 1/2 borax and 1/2 baking soda mix.
I tried mixing my dishwasher detergent with Borax and found my dishes and glasses sparkled. Not a spot on them. I no longer have to buy Jet Dry.
