Just wipe ordinary car wax on your headlights.  It contains special water repellents which will prevent that messy mixture from accumulating on your lights - lasts 6 weeks.

Rub the wipers with a cloth saturated with either rubbing alcohol or ammonia.  This can make even badly streaking & squeaking wipers change to near perfect silence & clarity. 

Just fill a spray bottle with three parts vinegar to one part water & spray it on all your windows the night before frost or ice is expected.  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!

Spray cooking oil on the rubber seals around your car's doors & rub it in with a paper towel.  The cooking spray prevents water from melting into the rubber and freezing.

Spray some shaving cream on the inside of your windshield & then wipe if off with paper towels.  Shaving cream has many of the same ingredients found in commercial de-foggers. 

Put some hand sanitizer gel on both the car key & the lock & you'll be able to unlock your car again!
