I've used rain-x quite a bit, plexus works and any decent brand wax will also work. Be sure to use a micro fiber cloth as I learned the hard way when using paper towels. They made the windscreen look cloudy afterwards. Just my experience though.
Rain-X has a caution on the bottle about using it on plastic windshields and face shields. It seems to me I tried it many years ago with no ill effects, though. I have never tried Lemon Pledge, but I have seen it recommended on other forums.
I use the rain-x more on the cars than the bike. After I went with a fairing on my 950t, I switched to a wax because the short windshield on the fairing was easily scratched. Most any decent bike shop should have what you need, or ebay and amazon can get what you need.
Thanks for your reply, the jury is out regarding Rain-X some say use it some say don't go near the stuff. I thinking of using a wax and brand suggestions
just use a paste wax and go heavy with it. i use turtle wax one heavy coat lasts about a week but i ride hundreds of miles a week, if you ride less it will last a lot longer is the windshield acrylic or polycarbonate ( lexan ) added benefit of hiding minor scratches too. i have fog off spray for my face shield tried it on the lexan windshield it worked only for a very short time like an hour at best
