Dirt, dust, pollen, sap, bugs, and debris land there and can make the glass cloudy, streaky, and hard to see through. If you use vinegar to clean windows in your home, it makes sense that's what you'll grab for your car. Since they are made of different types of glass, is white vinegar safe for your car's windshield? Read on to see when it's OK to clean automotive glass with vinegar and how to get a streak-free clean.Can You Use White Vinegar On A Windshield?Let's face it. Even if a car looks clean, it's probably covered in a layer of grime most of the time. Cars get dirty driving on busy highways and dirt roads, and collecting dirt, dust, and pollen as they sit outside. As water from sprinklers, irrigation systems, and rain rolls across a dirty windshield, it leaves minerals behind as the moisture evaporates. Spraying the windshield with fluid in your car's window washer system usually reveals just how much dirt has built up. And it only removes part of it.White vinegar is safe to use on car windshields, but isn't necessarily the solution to getting rid of everything that ends up there. Vinegar neutralizes alkaline substances, so it's effective at cutting through mineral deposits, bugs, and road salts. It's especially helpful in areas where cars are splattered or washed with hard water. When cleaning with it, it's best to dilute it with an equal amount of distilled water first. Even if you use an automotive glass cleaner, following up with diluted vinegar will get rid of any remaining mineral deposits.AdvertisementAdvertisementTough, sticky residue from tar and sap may be better handled by mineral spirits followed by a thorough cleaning. For the inside of the windshield, a commercial cleaner for automotive glass is better at removing smoke, fingerprints, and the hazy off-gassing film caused as vinyl, leather, and plastic surfaces release volatile organic compounds.When Not To Clean With VinegarVinegar is acidic, and it should be used with caution even when diluted. If it's not used correctly, it can strip car paint, damage rubber seals and wiper blades, and damage window tint, heat-rejection film, and protective coatings like rain repellents. If your windshield has special finishes, avoid using vinegar.It also shouldn't be used on a hot car. Vinegar evaporates quickly and it can leave heavy streaks if it's used on a windshield that's been sitting in the sun.When using vinegar, don't apply it directly to the windshield. Spray the vinegar-water solution onto a cloth and then clean the glass. This prevents the liquid from coming in contact with surfaces that it shouldn't.How To Clean A Windshield With VinegarYou'll need household vinegar with 5% acetic acid for cleaning a car windshield.

The longer they sit, the harder they are to remove.Putting a sunshade in your car's windshield can keep interior temperatures lower and reduce off-gassing. If it's a nice day, crack the windows to let air circulate.Avoid ammonia-based cleaners and abrasive cloths or paper towels that can damage the glass or leave small scratches behind.Fill your car's washer fluid with a good-quality cleaner.
