Anything that reduces your ability to see clearly while driving is a safety hazard–this includes haze on the inside of your car’s windshield. If you or your passengers smoke, much of this haze is caused from a buildup of smoke residue. Even if you do not smoke in your car, however, interior windshield haze is common. Pollutants from the environment and your car’s engine are drawn up from the intake vents, according to autogeek.net, and the result is a film on the interior windshield.
Mix one cup of white vinegar with an equal amount of water in a clean spray bottle. This is a glass-cleaning recipe suggested by mrscleanusa.com. Vinegar cuts through dirt and oily residue that many other cleaners won’t, and it is safer to use than ammonia.
Place towels over your dashboard to protect it from drips. Shake the spray bottle to mix the vinegar and water.
