After this, start wiping your car windows with it.

(Both the interior windows on the door and the front window.)
Distribute the shaving cream evenly on the whole window, then just wipe off the whole thing normally.
(You dont need any water for this.)

With this, no moisture can get to the window, and therefore it can no longer fog up.
This also ensures that your car windows can no longer freeze up from the inside.
