I don't have an F4 windshield but am posting this tip from the makers of the windshield for current owners (2nd attachment below).
Also included in this post is info on a current special for those wanting to purchase a F4 windshield at a better price (1st attachment below).
(Following info has been shamelessly stolen from The Dark Side... 
)
Awesome! Thanks for posting. Had not heard about using rubbing alcohol or white vinegar to renew.

It actually works really well.
I tried the white vinegar but it didn't seem too work all that well. Didn't want to waste my alcohol (bud lite) on it.
