Cleaning dishwasher and cloudy glasses

First, load your dishwasher with ONLY glass items- no metal or plastic.
Then, on the bottom rack, fill a cup (I use a measuring cup or a glass bowl) with one cup of household bleach.
Leave that cup upright in the rack and run your dishwasher through the wash cycle (NO detergent).
Then, stop it after the wash cycle, reset it, and fill the same cup with 1 cup of white vinegar.
Run the regular cycle, and ::poof:: you have crystal clear glassware and a clean dishwasher.
