Ok, so yesterday my lenspen arrived, and being curious as to what it was i opened it and had the urge to touch it.
But I didn't for fear of getting it dirty.


What I did is wipe my thumbnail with it and it left a black residue on it, after reading the packaging it says it uses some sort of carbon for cleaning.
My worry comes in with if I wipe my sensor with it, isn't it going to be leaving that same dark carbon residue on my sensor? Can't imagine that I want that to happen?


Thoughts?
