I used to use unscented sprays and it varied on which brands. Now, however, I've been thinking about how much money I might be wasting on this stuff. I've just been careful in the past not to expose my clothing and hunting equipment to any unusual "nonwoods" odors, wash and dry them without chemicals, and leave them outside during hunts. I've tried the spray's but kinda determined it probably was an unnecessary step if I continued to do the same things I've been doing. I've harvested big bucks without sprays in the past, no reason I can't now with some attention to details. I do try to hang stands well before the season, so it sees rain to wash away any of my left over odors. I don't know a lot of this stuff is probably wool being pulled over hunter's eyes. Including my scentlok suit, but I must say I get winded much less of deer downwind since I purchased on a few years back. But, I shower with unscented soap and what not too before each hunting outing, so really not sure. I'll be extra careful when ground hunting or putting on a stalk.
However, during rifle season I do not wear scent reducing suit, hunt in a ground shack a majority of the time, have oil on my gun, use a propane heater, have been known to have a dip and fart in my stand too. LOL!!!:) I do hunt the right wind though for each stand and that's helped more than anything I think.
