Seeing that winter is finally here, and the snow has started falling, it's time to get prepared! Here are a few winter car tips I received from a coworker. I don't know if they actually work, but it's worth a shot! (I can tell you I'll be trying the vinegar solution on my windshield tonight!)
Keep your headlights clear with car wax. Just wipe ordinary car wax on your headlights. It contains special water repellents that will prevent buildup accumulating on your lights...lasts for 6 weeks.
Squeak-proof your wipers with rubbing alcohol. Wipe the wipers with a cloth saturated with rubbing alcohol or ammonia. This can make badly streaking and squeaking wipers change to near perfect silence & clarity.
Ice-proof your windows with vinegar. Fill a spray bottle with three parts vinegar to one part water and spritz on all your windows at night. In the morning they'll be clear of icy mess. Vinegar contains acetic acid, which raises the melting point of water (preventing water from freezing).
Prevent car doors from freezing shut with cooking spray. Spritz cooking oil on the rubber seals around car doors and rub it in with a paper towel. The cooking spray prevents water from melting into the rubber.
Fog-proof your windshield with shaving cream. Spray some shaving cream on the inside of your window and wipe it off with paper towels. Shaving cream has many of the same ingredients found in commercial defoggers.
Frozen key locks? Put hand sanitizer gel on the key. Problem solved!
As I said, I'm not sure if any of these work... If you've tried any of them, feel free to share the results!
