i do my traps in a 35gal barrel with 1/2 of 55gal barrel as my wood heat containment area, that has 1" rerod pushed thru it 2/3 the way up. I toss in all my equipment and fill with water and bring to a boil, when i amalmost done i take a juice can of KEROSENE ( not gas as kerosene has lower flash point) STAND BACK and toss it on the fire which cause a boil over of all the scum. I let it sit over night and next day any wax that may have been left will be hardened and floatin on the surface and skim off.
USING THIS METHOD BE VERY CAREFUL AND KEEP UR WITS ABOUT IT
