I took 2 pairs of predators, 1 leather, 1 synthetic.
Soaked in a bucket of water overnight with a highly concentrated amount of Odor Ban.(found at Sams, Costco, Lowes). Then put in washer and dryer with 4 carwash towels. Please do not let wife know that I am amare of how to operate that type of machinery.
Let dry completely in sun and are just like new.
Walmart has a spray that if you use it after each session will control but not kill the beast.
If you can stand the smell then Liquid Lysol which is found at most grocery stores can be used in the wash and soaking process. It will kill anything but sometimes the end result is stronger than the initial smell. We should call the Dirty Jobs guy and see if he can handle it.
Good Luck
