If you want to learn How to Clean Car Windows, you’re in the right place! In this article, I’ll teach you the best way I’ve found to clean car windows, windshields, and glass in general over the years. When you’re detailing your vehicle, the glass should be the last thing you do to avoid re-contaminating it during the detailing process. So if you haven’t already washed and waxed your vehicle, now’s the time!

How to Clean Car Windows – Step 1: Prep Work

Make sure your auto glass is completely dry and free of debris, leaves, stuck-on sap, etc. If your windows are really grimy at this point, you’ll probably want to wash your car if you haven’t already. A little dust, water spots, and that sort of thing are just fine though, we’ll take care of those here.

How to Clean Car Windows – Step 2: Selecting a cleaner

Make sure you’re using a safe, high quality cleaner. Avoid household glass cleaners, which almost all contain ammonia. Ammonia can release dangerous fumes that should not be inhaled, especially in enclosed areas like the inside of your vehicle. Chemically, ammonia acts to dry out plastic, rubber, vinyl, and leather. For these reasons, you don’t want it anywhere near your car.

Instead, pick a glass cleaner designed for automotive use. For the inside portion of tinted windows (where the tinting film is), the best cleaner I’ve ever used is Detailer’s Pro Series Plex-All. For the exterior glass, I typically use a hydrophobic (rain-repelling) glass sealer after cleaning, which helps keep the glass clean and water-spot free during future washing, and allows rain to bead up and roll off during storms, so you don’t suffer as much of a visibility hit.

How to Clean Car Windows – Step 3: Using the Right Applicator

Always use a lint-free towel or microfiber cloth when cleaning your car’s windows. Trust me, it helps! Another trick is to use vertical motions on the exterior glass, and horizontal motions on the interior glass. That way, if you get streaks, you know which side they’re on, making it easier to get rid of them! Also, be sure to mist the cleaner on the cloth itself, rather than directly on the window. This helps prevent over-spray from getting where it’s not needed, like on your paint or interior plastics, leather, etc. If you have a windshield or rear window with especially hard to reach areas, consider investing in a glass cleaning tool like the one shown below!

How to Clean Car Windows – Step 4: Final Detailing

If you have small scratches or stubborn water spots on your glass, consider using a glass restorer like the one shown below in combination with an orbital polisher to remove them! This stuff works like a buffing compound, but is formulated specifically for automotive glass! It removes haziness, swirling, light scratches, and other imperfections to restore perfect clarity to your windshield and other windows.
