Well I finally got a smoked visor for my helmet. I have a scorpion EXO-700. It is a pretty good helmet for the price. I decided that i finally needed to get a tinted visor when i was riding with my wife and i was at a stop light and i had to have her tell me when it turned green (she has a tinted visor) because the sun was behind the light and it was like looking at a solar eclipse so i could see anything. Well anyways. I was wondering if there is any special care that i should know about the visor. I hear that they scratch easy? what should you clean them with? mine didn't come with any care instructions. Thanks.
