Earlier this year I bought an SA rated G-Force helmet to use on the track. Luckily it still has that new helmet smell, but I have a few friends whose helmets smell like the sweaty guys they are. 
So I'm wondering how one cleans the inside of a helmet. I thought maybe I could treat it just like any other interior space, but I wanted to hear if anyone has had any success with this.
Also If anyone has any tips for caring for the shell, I'd like to hear that too. I was thinking of just AIO-ing mine, it has a few small marks on it. TIA.
