I have the John Deere soft weather enclosure on an X590. Is there anything that can safely be used on the windshield to help keep snow from sticking? I've heard RainX is not good for plastic/vinyl. I've used Pledge spray furniture wax on motorcycle and snowmobile helmet shields with no damage, but they're hard plastic. It's usually the fine snow dust from the snow blower chute that drifts back and sticks, making me stop and get out to brush it off.
