Tell me, is taking a nylon to remove wax from the surface of a card considered a whitener, a solution or a chemical process. I'm awaiting your answer.

Removing the stain is altering the card regardless of the process. What PSA and SGC are saying is that they can more easily detect stain removal if chemicals were involved. Whether or not you can fool the graders with your card altering skills doesn't change the fact that it's altering.
