I’ve been caught out many times with a stinky helmet. You have a big day on the track or trail and forget to strip out the liner and put it through the wash. Then, in a week’s time, the helmet is rank and you have to slip on a smelly thing which distracts you for the next hour.
Motul Interior Clean has saved the day countless times. I give it a quick spray when loading my van and let it dry to eliminate odours and sanitise the helmet. I’ll never ride with a terrible smell inside my helmet again. — Matt Bernard
