Does anyone have a foolproof way of defogging windows. Every time itrains my windshield and eventually all the other windows fog up. It'spretty dangerous. I can clear the back window with the window heaterbut the side windows are a real problem.Is there a good product that you can spray on the windows to stop this?There doesn't seem to be a good way to clear them using the heater/ac.ST2001 CRV
