Something invisible on my wok

I want to wok tonight but I'm already confused by what should be the easiest thing in the world. Apparently there is some sort of clear lacquer coating on the pan which, of course, I cannot see. So after washing and "seasoning the pan" how do I know that this invisible lacquer is gone? How?! No mortal being can see something defined as invisible. It is pure madness. I'm off to cook an invisible dinner but I misplaced the invisible vegetables. Hopefully I can find my invisible knife...
