Didnt someone say one time to use Pledge on the visor?
I'll have to look that up..
http://www.totalmotorcycle.com/Theres a article about pledge on this site.....reads...
Quote-"As I've said, it works great on plastic of any colour and even on windshields and helmet visors as well. No, it doesn't turn clear plastic a yellow tint, it leaves no waxy buildup. It works like Rain-X in the rain and makes bugs come off easy as well as the dirt and dust.."-end of quote.
And they say to use "Lemon" Pledge only.
BTW-I havent tried this yet but someone here mentioned it at one time.Maybe Skatnbc
not positive though but someone said it works.
