I use 1 gal of vinegar in my dishwasher once in a while. Serviceman recommended. He said it's cheaper than those dishwasher cleaners aprox $1.00 a gallon.

How do you put it in? Just dump in a gal and turn it on?

Yep! Dump a gallon of white vinegar in the dishwasher without detergent and let it run. Dishwasher comes out clean as a whistle! I have a stainless steel tub and all hard water stains are gone.
