We have a rule: no lowering the car windows for at least two hours after getting a car wash. Doing otherwise means streaks that you can’t get rid of without physically getting out of the car and wiping them. For anyone obsessed about keeping their vehicle clean, this is a reality. But now with the ViperSwiper, those days may come to an end. It’s a strip of rubber that you install on the outside of your car, sandwiched between the window and its regular rubber lip. The ViperSwiper then squeegees your window clean as you roll it back up, getting rid of any streak marks that would normally be there after a wash. It does require self-installation, but it seems pretty straightforward and requires no tools other than a scissor. And it will need changing every 3 to 6 months, like regular wipers. Fortunately, it’s pretty cheap, at $20 for two 40 inch strips that you cut down to size. If the Kickstarter funds, you can expect them by February 2016.
