How do I address white residue or spots on glassware and dishware?

Confirm cloudiness is due to hard water by soaking the item in white vinegar for 5 minutes; if it disappears, adjust the detergent and rinse aid amounts. Use the Hi Temp and Sani Rinse options, and run a vinegar rinse by putting 2 cups of white vinegar in a glass measuring cup on the lower rack with a normal cycle (Heated Dry off, no detergent).
