How do you clean your faceshield, on your helmet, while out riding? I'm not a daily commuter, but instead tend to take 4 to 6 hour excursions on the weekends in the mountains and rural areas. I might go 3 hours before seeing a gas station or restaurant. Often times, I'll have a head on collision with an insect that leaves a yellow gutsy mess smeared all over my helmet windshield. Making it hard to see. In the mountain areas there are lots of bugs. So, I typically want to keep the faceshield down. But, its hard to see through bug guts. Is there a simple method to stop and clean this mess off? Do I need to stock up on those little KFC handwipe packets? Or do you just deal with it until you reach the next town, restaurant, gas station, etc?
