Cleaning car windows can be a pain without the right tools and techniques. Often people set out with Windex and paper towels to clean their windows but end up with streaks and paper towel fibers left on the window. Most Windex formulations have ammonia in the mix, which dries out plastic and rubber, damaging window tint causing it to peel. Paper towels are typically multiple sheets of paper towels that are glued together, this glue gets onto your window and contributes to the streaks. These car window cleaning tips will have you cleaning glass like a pro and achieving streak free results without the headaches and hassle.

  11. If you are diluting your glass cleaner always use distilled water. Distilled water does not contain additional gases, minerals or contaminants that tap or other types of water contain. It’s good practice to dilute all cleaners with distilled water because tap water is often considered “hard water” with a high mineral content. These minerals are often left behind on the surface once the cleaner or water has evaporated off the surface producing water spots.
