Sorry if that has too many failure points for you and isn't as simple and safe your idea of wiring up an electrical accessory and a switch so you can put the cheapest heating element you can find on a plastic bottle filled with a flammable liquid.

That's why I talked about it and didn't just say do it. You could have a fire even if the hose to the wiper nozzles split.

There are more brands that are non-flammable.
 
im going to admit to something. i had no idea washer fluid was flammable untill yesterday. all i look for on the bottle when i buy it is its good for below zero temps, never thought twice about it being flammable
 
I used to mix it with the water for the water injection on my 78 chevy race truck. Back in the early 80's.

Crap, I am old.
 
I learned when I started some on fire. I was working on the back of a truck and all of a sudden fire was leaking in a stream out of the frame rail. I got the fire put out but was confused by this blue, flammable liquid that didnt smell or taste like any auto fluid i was familiar leaking from the frame on the back of this truck. Truck had a rear wiper and washer, but a common reservoir under the hood with two pumps.

On a related note, I saw an article about some folks that are developing a wiperless windshield.
Details are being guarded right now until all the patents are in place, but it seems to involve an ultrasonic transducer that vibrates the glass at about 30KHZ, and the rain, snow, and bird crap just bounces off.

Mclaren is making that if I remember correctly.
 
It's methanol for the most part. Guys that hotrod diesels and run "water meth" all they do is fill the injection reservoirs with cheapo winter washer fluid. Guys that care about their engines buy pure methanol and cut it with water themselves in order to get consistent ratio. Washer fluid methanol ratios are all over the map. There's no real quality control cause it's not regulated.
 
The purple stuff or anything fancy premium like that good for -45c or more uses more than just methanol. Some kind of Teflon compound I saw in one.

But I thought I should mention this phenomenon. The engine bay air heats the nozzle area and the feed lines going to the sprayers. The mini van does this. My ford service truck does it. There's no heater. Just engine bay air by convection or something.

never noticed this befor
 
I can't say every vehicle does it. But the ones I drive sure do. I think it has to do with the under structure of the hood itself.
 
Have you looked at the alphatherm units? Got one in my pickup, works like a charm...heated fluid when you hit the button
