I also have used the water and newspaper on windows at home. Yes, it works great. The news print seems to polish the windows. On the other hand I also put in a few drops of dishwasher detergent into bucket of water and then add a little ammonia. Then I use a squeegee or blade like window washers use and this too works very well...no streaking. then I buff with dry terry towel.
