This is what I do, if it works no clue, but it seems to me it does. I wear a military type chacroal suit. After a few hunts I use a commercial grade heat gun all over it like a blow dryer a few minutes on each section to reactivate the charcoal. If your on 1 spot to long it'll burn a hole so you'll have to watch it.
After a session of this is smells just like when ya took it out the plastic. You know, that carbon smell. The dryer just doesn't cut it. Either way good luck!
