RE: Scents...Can you keep or chuck?
What you probably want to do is buy this project made by Hoyes Outdoor Products called "Scent Ammo". It's a porous pellet that absorbs nitrogen & ammonia from any urine or urine based hunting scent, thus increasing its duration of effectiveness. Not only can you prolong the life of a scent, but you can also repair scents that have "gone bad". Hope this helps.
Good Luck
