Visor and Helmet Cleaner

Plexus was my choice till it wrecked the costing on my Shark Evoline, luckily my Shark Pro Carbon seems to be also coated but with something better and I was advised to only use water on it, that and soft cloth brings it up spotless
 
I just use those little "wet wipe" things they sell for cleaning eye glasses lenses for my helmet and face shield.
