In a pinch, you can make antifog from detergent. A few weeks ago, I put a TINY smear of Dawn on a damp paper towel and rubbed that on the inside of the windows. Then I kinda polished it off with a dry paper towel. The second step may not have been necessary, but it looked like I might have laid it on too thick. Maybe I should have let it dry first to see. You don't want enough detergent to make it look streaky when it dries, but enough to provide a surfactant to flatten the tiny droplets that cause the fogging.
It worked fairly well. After I run the climate control timer for preheat, the areas I didn't treat are very foggy, and the treated areas are barely foggy. Half a minute of defroster use after starting the car and all is well.
Didn't read all four pages, so sorry if this is redundant.
