The cedar limbs in the dryer might be a good idea. I usually just put a few branches in a trashbag with my scent free clothes. The woods I hunt are mostly oak with plenty of cedars mixed in, so I use bags with oak leaves and soil from the area also. I just have all my clothes and coats and gloves that I will be wearing for a week laid out in bags full of natural scents. I only wear them one day before washing in scent free detergent and leaving them bagged overnite to soak up the smell of oak leaves or cedar again. Then of coarse wash yourself with scent free soap just before you dress to hunt, and use scent away type sprays on your boots. The deer will still smell you but they may not know you are there, if they smell stronger natural scents, they may think your scent is from hours or days ago because it is not strong. You got to do what you can, keeping your scent from them is best.
The thing is a deers nose can smell every scent separately. When we smell a strong odor we cannot smell anything else. If you could detect individual scents like some animals do you could smell every ingredient in any recipe separately. Like drugs sniffed out of all the cover scents used to fool a dog, plus the natural surroundings the people around, the tires on the car etc.
So you, as a deer would smell human odor, probably the scent free soap, the clothing, the different plastics that make up your gear, the spec of blood left on your knife from last years buck, steel, gun oil, powder residue, and or the stuff you cleaned your muzzle with, what you ate and drank for breakfast and on and on. This recipe makes up a hunter and each and every scent is detected separately. So like I said, do what you can with cover scents, it may help, but stay out of the wind and use thermals to keep your scent away from their nose.
