I never wash my clothes with that stuff, and do not use all those different cover scents, never have. I get deer every year. I go down alot all year long, I pee all over the area around my cabin, stands and feeders. The does are so used to me and not afraid that they come up and watch me and the bucks are so used to my scent they are not so spooked. I have a fawn without a mother that will not leave me alone, see her almost every day I'm there, comes within 20 ft of wherever I am. Sunday she came up and layed down behind my shed and watched me. She makes a great live decoy. Kind of cool.
My point is, deer are alert to smells that are out of the ordinary. If they smell something they are used to as not a threat, they are fine but put an unusual smell out there and they will be alert. Leave your scent in the area more than a couple of weeks a year!
