Windshield de-icing

I have two related questions:

1. Are there any natural substances to help keep the car windows from icing up?

2. Are there any natural substances to help keep the interior windows from fogging up?

Thank you,


Interior window fogging can be minimized by turning off recycle air control. Cripes washer fluid is only a naturally degrading alcohol that lowers the freezing point. As 75% of pollutants are caused by industry I think your concern over green windshield washer is nuts. Rainex has some good products, there is a defroster button on your car that works well for many…

“Natural substances”? No.
I suggest that you follow waterboy’s advice.

Additionally, please remember that substances such as arsenic and cyanide are 100% natural, but that does not make them safe. Commercially-available products for deicing and for preventing window fogging will not poison you–unlike some natural substances.

Glycerin will keep your windows from fogging up but I don’t have any idea about what you consider natural or even how glycerin is made.

The only thing that’s worked for me…is “Park in a garage.”.
