The interior and exterior of car windows should be cleaned right along with the rest of the car; however, streaks often appear after cleaning car windows. Clean car windows and leave them streak-free by using the appropriate products and methods. Not only will your car look presentable, there will be no streaks, dirt or grime inhibiting your view while driving.
Clean out the interior of your car before cleaning the windows. Dust off the dash, steering wheel and other surfaces in the car. Vacuum the seats and carpets. This will remove dust and dirt that could be stirred up while cleaning, getting on the windows.
Use auto glass cleaner to clean car windows rather than the glass cleaner you use in your home. Auto glass cleaner can be purchased at most auto supply stores. Make your own glass cleaner if you would prefer by mixing 2 cups filtered water, ½ cup white vinegar and ¼ cup rubbing alcohol into a spray bottle.
Fold a microfiber towel into a square. Make sure that the microfiber towel you choose is lint-free. Microfiber towels designed specifically for cleaning glass can be purchased at most auto supply stores. Spray a generous amount of the window cleaner onto the towel. Avoid spraying the window cleaner directly onto the glass.
Clean the windshield of the car first. Move on to the driver's and passenger-side door windows, back-seat passenger and driver-side door windows and then the rear window. Work on the outside of the windows first, followed by the inside.
Use vertical strokes to clean the outside of the windows and horizontal strokes to clean the inside. This will help you to determine which side of the window any streaks are on once you are done cleaning. Use a smooth, sweeping motion and apply a moderate pressure when running the rag over the glass. Reapply more glass cleaner, as necessary, when the rag begins to dry or in between windows.
Roll down the car windows to wipe down the top edge of the glass. Lift up the windshield wipers to thoroughly clean the windshield. Be sure to get into corners and along all of the edges of the windows.
Go over each window with a clean, microfiber towel. This will remove any residue and smooth out any streaks left on the glass. Inspect the windows thoroughly to locate any streaks and go over them again with the microfiber towel.
Do not use paper towels or tissues when cleaning car windows. If your windows were really dirty, change the microfiber towel you are using to a clean one during the cleaning process. This will prevent dirt and grime from being reapplied to the windows.
