The other day I was out riding on a particularly filthy damp day. My visor quickly got covered in muck, and I resorted to using my glove to clear it every now and again. It got me wondering whether there were any products out there to help keep it clean whilst riding. I came across this video on YouTube. Since then I have looked into it a bit further and found that Mr Sheen seems to be quite widely used. What do other members use to keep their visors clean whilst riding?
