the wife's kia fogs up to no end. was always an issue but I would just put the window down to equalize temps between outside and inside then put it back up. now with a little one riding in back, I'm reluctant to do that especially in the winter early spring time. anyone have any good and easy treatments for this kind of problem. I know there are a bunch of car people here.

the condensation occurs on the inside of the windows, just for reference.

thanks
