With respect to scent: Yes, brush teeth and shower. I personally use a tiny bit of unscented clothes detergent to shower with as it only costs pennies vs. dollars for special hunting soaps. Rinse your mouth well after brushing with std toothpaste or use baking soda. I use a scent-killer type spray on clothes that I believe works - I have had deer pass 10-ft away while hunting on ground in a blind! For even more cover, store your hunting clothes in or near the corn you use for bait. And keep your clothes outside somewhere away from house or auto/gas odors.
