Why does dishwater or the dishwasher leave spots on glasses?
The spots that may appear on glassware after washing and air-drying are caused by nontoxic minerals that remain on the glass when the water evaporates. Sports on glass shower doors appear for the same reason. Commercial products are available that allow the water to drain from glassware more completely.
