It doesn't work! I sprayed the concoction on my car windows last night and it was just as icy this morning. I'm also out of windshield wiper fluid, and my ice scraper is crappy.
I confess I did not wave my hands around, nor recite the "I defrost thee" incantation. That was really more for you guys.
I'm going to try a stronger concoction of just pure vinegar (no water added) to see if that does the trick. And I'll be getting a new ice scraper...does anyone know if antifreeze is really all that important? Maybe I should check my levels of that...and add more windshield wiper fluid. My dad taught me how to do this a long time ago so hopefully I can remember.
Will keep y'all informed as to whether the more vinegar solution works. I'm also going to spray it on a lot more than last night. Stay tuned...
