No plexus, no 409, no wax etc. - Just like they told you from Arai - all that stuff does is weaken the helmet or make it brittle.
All my helmets still have the original visors and all *could* still be in use - except one that was in a wreck. I retired the others at 5 years after in-service or 7 years after manufacture - because my head is worth it.
The Arai factory told you...
"Whatever you're using to wax or clean your helmet STOP USING IT! It's killing the plastic."
"Arai suggested nothing but water to clean the helmet."
I would go by what the manufacturer says vs. what the forum members say, even though I am always right
