My son and I tried a double boiler set up in my kitchen, bad idea. I was scraping wax drippings for a few days. My buddy and I decided to get the crock pot and set it up at the meeting room of our rod and gun club. We dipped knife and axe sheaths, belt pouches, and anything else leather to try it out. Once we were done, cool it down and store it away. No mess to clean up.
