Here is something I have done.
I have a wood burning stove in the basement. One morning the fire was completely out. As I was poking around, I noticed several large chunks of charcoal.
I took them out and place in a coal bucket. I noticed they had no smell. Didn't smell like burnt wood or anything. I broke them in half and they were charcoaled clear through.
I light bulb went off in my head. At the time there was a lot of hype about charcoal sprays and clothing. So I decided to try it out. I put several chunks in the tote with my baking soda washed clothing.
After hunting one warm day, I peeled off my clothing and put it in a tote with the charcoal chunks.
The next time I got it out, I gave it a sniff test. To my surprise, I couldn't smell a thing.
I realize I do not have the nose of a whitetail, but it definitely made a difference. Those sweaty clothes should have smelled bad. They didn't smell at all.
Anyway, I've saved several chunks and put it to use today.
