I don't remember which one of the three most popular outdoor magazines (Sports Afield, Field and Stream, or Outdoor Life), had it, but in the 50s and 60s one of them had a little column called Tap's Tips. Much like this forum, people would send in their favorite outdoor tricks, and he would pick one a month for his column. The most memorable one was cleaning a crusty frying pan by hanging it off the end of a boat dock. The water was supposed to soften the mess, and the minnows and panfish would clean all the cracklings out of it. I never tried it, because some of our camp pans would take 15 minutes of boiling water in them, and another 5 minutes of steel wool and elbow grease, so I suspected the fish would never have it ready for breakfast.
