To clarify
Glass cleaners in a spray bottle work fine. The only problem is over spray on the dash and upholstery. As it is difficult to direct the spray of glass cleaners, you will have the best luck spraying one side of a clean towel, wiping the glass, and they drying with the other side of the towel. Many professional detailers use plain water for wiping and cleaning the windows and dry the glass with newspaper. Unlike paper towels and most cotton towels, newspaper does not leave behind lint and the ink acts as a glass polish. The only draw back to this method is the newsprint ink on your hands when you’re done. Be sure to wash your hands before touching your upholstery.
