I'm not sure how much a replacement windscreen will cost so I am trying to take as good care of the original one as I can. After every ride I use a microfiber cloth soaked with plain water to gently wash the bugs off, then I dry the windscreen with another microfiber cloth. Then I spray and wipe off Plexus. My RT is now a year old and the windscreen looks pretty pristine, other than a small scratch where a rock was kicked up from the roadway.
