How to Clean the Inside of a Car Windshield

Dirty windshields are not just ugly; they are also a driving safety hazard. It’s easy to remember to clean the outside of the windshield, and of course windshield wiper fluid takes care of the outer windshield between more thorough cleanings. The inside of the windshield is a whole different story, however, and drivers often forget how quickly the inside can get dirty and interfere with safety.
Although cleaning the outside of the windshield is somewhat easier than cleaning the inside, due to the curve of the glass and the dashboard in the way, a little patience and preparation will go a long way in keeping the inside as sparkling as the outside.
Instructions
1 Wipe the inside of the windshield completely with dry paper towels. This gets rid of surface dust and grit and will make damp cleaning easier.
2 Spray corners and edges of the windshield with auto glass cleaner. Make sure you are generous with the spray—too little and it won’t work as well.
3 Clean the corners and edges first, with a microfiber glass towel, as this is where most dirt collects. Cleaning these areas first prevents spreading dirt and debris over the rest of the windshield.
4 Spray half of the windshield with the auto glass cleaner. Wipe down that half, using circular motions, with a microfiber glass towel.
5 Dry and buff the window with a fresh microfiber towel.
6 Repeat Steps 4 and 5 for the other half of the windshield, using fresh microfiber glass towels.
Tips & Warnings
•Always use clean towels to avoid spreading dirt or grit over the glass. This helps prevent streaks and tiny scratches. In cold or hot temperatures, bring the car into the garage, if possible, to let the glass warm up or cool down a little before cleaning. Clean your dashboard before cleaning the inside of the windshield. Air currents from fans, air conditioners and outside breezes blow dust from the dashboard onto the windshield.
•Use only glass cleaners made specifically for auto glass. According to Armor All and autogeek.net, other glass cleaners may contain ammonia, which can harm some car surfaces.
