My Lexan windows seem very susceptible to scratching!
I have been using boat soap and warm water, taking care to use a very clean bucket and a microfiber mophead, followed by a chamois.
I'm still getting fine scratches...
On sorta the same subject,
Anybody have a great product for water repellent on Lexan?
I have been using Rain x for plastic, but it doesn't work nearly as well as the Rain X for glass.

But you can't make him ski...
