Paper contaminated with tear gas

I received a request about decontaminating some family papers that
were heavily (49 cans) exposed to a tear gas substance called "CS"
that formed a powder that is still active and irritating after
several weeks. I provided some Mylar envelopes, hoping that they
would protect the people handling the papers, and they did help.
Does anyone know what the chemical is, or what might neutralize it?
