Personally, to be scent free, I wash all of my hunting clothes in Scent Away laundrey detergent. Then I spray them all down with Earth Scent, and throw them in a plastic tub with earth scent wafers. I wont put my hunting clothes on until I'm ready to head in the bush.

As far as scent trails go, I simply tie a piece of string to a tampon, pour my Tinks right on it and drag it right behind me towards my stand. I also get film cartridges and drill holes all around it, fill it with cotton balls and spray some Tinks inside, put the lid back on, and then hang them on a limb of a tree about chest high.
