Cleaning glass without lint
To clean a window or mirror without leaving a trail of lint behind, keep the rag moving in a smooth circular motion, not back and forth. Changing direction is what breaks off the tiny fibers that become lint. Even starting and stopping creates lint. See this for yourself by squirting a small spot with cleaner, then scrubbing it back and forth with a paper towel. You’ll soon see a little pile of lint right where you changed direction.
It doesn’t matter whether you use paper towels, cloth towels, or old T-shirts. (I like to use paper towels and to add a single dry sheet to the wad as necessary.) Just keep moving in smooth circles, always in the same direction. Forget about expensive window-cleaning solutions; a quarter-cup of white vinegar in a quart spray bottle full of clean water works better than anything I have found. To avoid streaks, clean a small area with the damp towel, then polish it with a dry one before the streaks have a chance to dry on their own.
