Re: Defrosting frozen windshield fluid
Don't have that problem with mine and its been into the single digits most of the week. I use the Prestone De-Icer washer fluid since having a problem with the rear washer fluid line freezing up in our Ford Escape. Also keep a spray bottle of it to use as deicer. They also marklet a de-icer booster which is basically just different alcohols.
