What do you use to clean your windshield and your visor on your helmet? I have read some post that say to use “wax” after it is clean to help with rain run off. What kind of wax though, car?
Wet an old T-shirt, squeeze out, and lay on your windshield for a few minutes. Use the same t-shirt to wipe off bugs, and dry with a micro fiber towel. I've tried all the "magic formulas" and none work better. You can follow up using a wax or other plastic safe 'protectant' for bugs, rain beading, etc. Try this...it is so simple and effective.
I'll second that old t-shirt method. I just soak it in warm water and lay it on the windshield for a few minutes. If needed I use some of that H/D bug remover after the shirt has been on for while. I use the same method for my helmet visor. I haven't used any of that rain run off stuff yet though..
