Newspapers really are the best thing to use when wiping your windows down. For years, I wiped mine with a cloth, and I always had ugly streaks. Newspapers totally remove the streaks.
My ex-boyfriend first introduced me to using newspaper to wipe glass clean, and I could hardly believe how clean it got my windshield. I simply sprayed it with a glass cleaner and wiped a newspaper across it until it was dry.
Since then, I have been using newspaper on all my windows. I don't usually crumple it up until I have been using it awhile and it has become moist. I find that I get more use out of each sheet this way.
