I think this is the same as Hondaline.

S100 is great for the really grimy parts, but it's expensive also. Just spray it on, let it sit for a minute, then hose it off. Crud just melts away.

There is no problem using alcohol on Lexan (polycarbonate). That's what we used to clean the Lexan when making F-16 canopies (used 99% isopropyl). Just follow the alcohol wash with distilled water and give it a good dry with a microfiber cloth or a cotton baby diaper.

CLEAN cotton baby diaper.

Lemon Pledge on everything for the last 15 years. It works on metal, plastic, windshields, seats, and anything else you can put on a motorcycle. 

Soap and water

Since I'll have several months to tinker and clean up my new (to me) '86 Concours, figured I ask a question I'm certain has been thoroughly flogged before.....what are your favorite cleaning products for various surfaces?  Painted plastic...aluminum/alloys....windshields....seats.....rubber....engine detailing....etc.

Did I hear correctly that CD2 has been discontinued?

Used S-100 for years. Works great and if not mistaking is the same thing as Honda Brite only cheaper.

Clean?? 
It'll lose all it's character,...... besides it's only the rust and crusted on road grime that is holding it together.

<LOL>

+3 or 4 on microfiber cloth. It's the only type of cleaning device that touches my bike.

I use nothing but Pledge and microfiber rags. Steve

You can get Pledge Wipes in easy-to-use, resealable envelope if you wish.  Not as soft as Microfiber cloths I know.  FWIW...
