Although a heated fluid is possible it seems messy to me. It is possible to heat the windshield directly with electrical resistance elements as is done with the rear window or alternately with hot air blowers from the inside with less fussing with fluids that must be replaced.

I bought these for may roommates almost exactly a year ago: <a href=” http://www.topoftheline.com/winter-windshield-cover-snow.html”>Winter Windshield Cover orHaving a hot liquid hit a potentially cold piece of [safety] glass seems like a bad idea to me. Better yet, drain most of your washer fluid (I usually do this in multiple sessions to avoid stressing the pump motor) and add a gallon of generic -30 "winter windshield fluid". A few winters ago it was consistently -20F and this stuff was great. I think the type with methyl alcohol is most effective at removing frost without using a scraper. I found a link to a Prestone brand that claims additional mud/gunk clearing powers. FYI, I do not believe winter windshield fluid contains ethylene glycol or propylene glycol which is engine coolant a.k.a. antifreeze.

foiled again!

I think the idea has merit, if it is not already used that is. Can't see how it can be messy, or how the water couldn't be heated to just a tepid temp.

Obvious thing i'm going to point out;Water is usually heated as a biproduct of running the engine for a while.

My 1999 Audi A4 already heats the windshield wiper fluid. You're about 7 years too late.
