Make your own, will not leave a film and will reduce drastically the amount of fogging over time. Here is the simple formula.
denatured alcohol and most importantly water distilled water. Not have any contaminates is important over time. The ratio of alcohol to water is 10 parts water to one part alcohol.
How to use:
1) Wet window using sprayer
2) Rub hard over all the surface ( I know, no different then other cleaners )
3) Now rub the area with an absolutely dry paper towel, it will remove what ever was on the surface and will be feel really dry with lots of resistance.
4) Do it again, until all contaminates are removed.
PS: Practice on a mirror and you will understand what I am talking about.
