I always air dry my clothing outside for a couple days at least. But during season, if I happen to be hunting in rainy conditions, I'll toss my clothes in the dryer to dry out. I use the earth scented towels and never had a problem spooking deer. I usually will throw a couple in each of my clothing containers as well to help mask up any scent. I also periodically throw just my under garmets in the dryer with a couple to help mask up oders in them as well.
