Nothing works to kill scent completely. Just need to fool the deer for a moment. All you can do. A cover scent is much better. Hard to eliminate odor. You produce it all the time. You would have to sit in a vate of it in your tree. Hunt with a good cover and the wind and you will be successful. I use a washing machine for all my gear that has only had all clear used in it for its entire life. Manage the scent of the chit you take with you and bathe in antimicrobial soap. I use Shines White Oak acorn for cover.

Dead Down Wind is a product founded by a medical company. In its primary form it was to destroy the odor of rotting flesh in hospitals. Get some and test it yourself. Cut an onion and spray your hand afterwards. You will be a believer then. Hunt safe

Here we go again. Just because something eliminates odor, to the point that we can't smell it doesn't mean animals can't smell it. We have a terrible sense of smell. A dog can find dope submerged in a gas tank. Dogs are used to find arsonists. Dogs can smell cancer cells in humans. Deer have a better nose than dogs. Do you really think that some manmade liquid is going to make any difference? How do you know the deer can't smell the scent killer? Gimmick to rob people of their money.
