What is the MSDS for windshield antifreeze can't be good for the environment.

At one percent over flammable I can't see myself putting a match to the windshield to see the result. Mind you when the window is covered with snow a little squirt and a match.

 

The first thing I do with any vehicle is burn through the kool-aid they put in the washer tank and fill it with Rain-X. Unfortunately, the dealership decided by truck needed it's tank refilled with more blueberry liquid, and that night it froze over. I ended up getting a hand pump from the hardware store, and emptying as much of the fluid as I could once it thawed. I sprayed the rest out and topped it back off with the good stuff. I have never had an issue with the Rain-X freezing. I figure if it's cold enough for it to freeze, I won't be leaving the house anyway
