Can i get this locally from an autozone or do I have to order it
Yes you will have to order it from AG. If you want something OTC, try the de-icing bottles (spray) prestone sells at autozone they work decent on mild snow/fost/ice. Also use some kind of glass coating which will help frost/ice come of faster.
Hey guys I have been sticking to using the heat and scraping away, however, this takes 10 - 15 minutes depending on how cold it is and how thick the frost is.
Anyone use any sprays to cut through the frost?
I've had mixed experiences using deicer sprays. Yeah, it works, kinda... it's most effective on light accumulations and as soon as the ice softens you'll still need to scrape. The moisture on the glass tries to refreeze until the defroster starts putting out heat. The alcohol content is a better ice preventative than it is a deicer. Plus after you get rolling it ends up all over your vehicle.
Your question was for the "best" way to deal with icy glass... a heated garage
Assuming that isn't an option, anyone that has to park outside in a serious winter climate would do well to bite the bullet and spend a couple of hundred dollars and have a remote starter installed. Swipe the money from your budget for others' gifts if you have to. The very first time you walk out to the car after it sits in freezing rain... the kind that's almost impossible to scrape off until you get some heat on it... and you slip inside your pre-warmed cozy and ice-free vehicle while the wind is whipping around your frozen coworkers/neighbors/friends while they're hacking away at the ice on their wondows you'll consider it money well spent and wonder why you didn't do it years ago!
Of course, if you forget to preset the heater controls when you got out of the car it's all for naught. Don't ask.
