Camping has long been a tradition in many cultures. Long starry nights in nature, evenings around the campfire filled with stories and songs. There is little surprise that generation after generation take up this "get back to nature" activity.
Unfortunately, after such a wonderful night around the fire, a lot of us wake up with the question of how to get campfire smell out of clothes.
It can often linger far longer than anyone would appreciate, and with multi-day trips, or non-machine washable clothes, this can be a big issue.
