Clean windows with a mixture of ordinary cornstarch and water. Half fill a bucket with cold water and sprinkle in about a third cup cornstarch. Mix together until cloudy. Use a sponge to wash the window. Wipe clean with newspaper. Cornstarch tends to settle in the bottom of the bucket so stir it occasionally. Newspaper leaves no streaks.
