The basis of the argument against them is that in order to "recharge" the carbon you have to reheat it to way higher a temperature than a dryer can reach, to a point that the cloth would burn up as well.

Anecdotal evidence says it works, physics/chemistry says it doesn't.

My question is can it be 'a little bit' recharged by getting to a temp a high setting on the dryer can get to.

On the anecdotal evidence its impossible to say for sure that the deer would or wouldn't have smelled them without the scent block/lock clothing.
