I know this is an old post and I am a new member on the site and so far love what I am reading, very imformative. I have used almost all of the brands out there and I do believe they all work for a certian amount of time, but all of them will stop working and the bacteria that causes the odor will return.
A buddy of mine bought a couple of bottles of stuff a few weeks back and i'm telling you right now it is by far the best stuff I have used ever. Its name is BioExtreme and it is an all in one odor killer. I mean you can wash your clothes, your body in the shower, spray down your clothes and use it in the field all from the same bottle not three or four like the others want you to buy.
I used part of mine to test it on stuff and it worked on gas, and smoke instantley and it did not come back I mean it was gone. So far I have used on the stand this year three times and have yet to be busted and it saves money at the same time.
I have not washed my clothes yet but I am going to, and when I used it in the shower it did not suds up like others I have used but my hair was squeaky clean. I have just used as it said to and sprayed my whole body down and the inside and outside of my hunting clothes and I am telling you this stuff works.
I am sold on it and wont be spending anymore money on the other stuff until somebody else comes out with one that will work everywhere like this stuff does and cost less...
check it out at www.bioextreme.net
and see for yourself, like I said I have not been busted since I started using this stuff and I have always gotten busted using the others...
