Question: How to wash your windows without leaving streaks?

  Options: 
 A. You can purchase a window squeegie with foam along one side and a rubber strip along the opposite side. Dip the window into hot soapy water and then vigorously wipe down the squeegie with a soft lint-free rag. Observe the results and pick any lint off the window that remains.
 B. You can purchase a window squeegie with a strip of foam on one side and a rubber strip on the other. Dip the foam side into hot soapy water and vigorously wipe down the surface of the glass. Then flip the squeegie over and in long smooth strokes, glide the rubber side over the glass starting at one top corner, going back and forth without lifting the rubber off the glass. When you have completely removed the water, observe the result and dab any drips or missed spots with a lint-free rag.
