    The missing rear window wiper is a big problem for me this time of year. Snow accumulates while driving and no matter what speed you are going it won't blow off.

    Spring snow in Colorado is very wet and very sticky. It will stick to vertical surfaces and even to the underside of surfaces if the wind blows it up under a soffit or similar.

    I just took this picture. This is a string, about 1/8 of an inch in diameter. The snow cylinder is around 4 inches in diameter. You'd have to drive about Mach 1 to get this stuff to just blow off the rear window.

    When I get the wet sticky snow on my back window, I just wipe it off and turn on the defroster. The remaining and new snow melts right off. Putting Rain-X on the window also minimizes sticking.

    My Prime has seen dry snow, wet snow, in-the-middle snow and once the window is cleared by hand it stays clear while I'm in the car.

    Not me.

    I've had it start clear (like this morning - it was in an insulated garage all night) and accumulate while I'm moving even with the rear defroster running.

    Have you treated the glass with anything like Rain-X or similar?

    Yes...with Rain-X.

    One more thing that may help - clean the window and polish it with 0000 steel wool, then reapply the Rain-X. This will make the glass as slippery as possible. But, even that may not resolve the problem you are having. You could try the Mach 1 approach though, but mileage will suffer accordingly...

    Wow! Snow, now? It's the end of May. The official start of the summer is in just a week. :eek::eek::eek:
    I never felt needs for rear wiper even during sticky snow. None of my previous sedans had a rear wiper, and I did fine. Prius has very bad rear view window to begin with, and I often have so much cargo in the back blocking the rear view anyway.;)

    Here's what I do to all the glass, a couple of times each year:



    Works like a charm. (I used to do the 0000 steel wool/Rain-X treatment, but this is even better. I've been doing it this way for the past 4 -years. Thank you Chris Fix! :)

    Any time we get a wet snow. Probably 10 times a year.

    is there a way to put a wiper on the curved glass? looks problematic.

    i don't have the energy to do that twice a year. i rarely clean my windscreen to begin with. maybe once a year with windex and paper towels. does an awful job, but gets most of the plastic buildup from the dashboard

    Wait, I thought global warming will take care of snow... has it been cancelled?

    This does not appear to be the case.

    Has anyone used Aquapel or any longer lasting treatment? Rainx doesn't last very long, and wax isn't much better in my experience.

    At $3 - $5 for an application to less than the entire car (perhaps front and rear windows at most per applicator), Aquapel is pretty pricey compared to a $4 bottle of Rain-X. I'd be interested to hear how long it lasts in the real world. I get a few months out of Rain X.
