I have been using Stoner's Invisible Glass Cleaner for about 1 1/2 months now. Though I find that it cleans well, I noticed that it makes my windows fog a lot to the point that I am unable to drive with my windows closed AM or PM without having the defogger on. I've heard Meguiars does not cause this problem, but I have not been able to find it anywhere. I've tried Kmart, Walmart, Target, Autozone, Kragen, Albertons, Vons, Ralphs, and nothing. Does anyone know where I can get some (don't want to pay shipping charges at autogeek just for this).
