Invisible Glass Spray - Streak-Free Window & Glass Cleaner for Cars, Mirrors, and Home Use

I don't know who came up with this product, but it is worth it's weight in gold. We are in the process of selling our home and this cleaned up gunk from the inside and the outside of the window (with a bit of elbow grease). I used a microfiber cloth as other reviewers suggested and the dirt and dust vanished. In some cases where there was heavy accumulation, I did follow with some paper products just to remove any small residual streaks. It also worked great on mirrors and the glass in our entertainment center and bookcases. It has a slight smell, but much less than the other popular glass cleaner. My eyes water and nose burns for hours after; not so with this stuff. You would do well to have some ventilation available, but that is true of any cleaning product. I really cannot say enough about this!
