I used to be obsessed with scent reduction. However, as I've aged and gotten lazier, not so much. And my success has not declined. However, there are still a few practices I still follow. All hunting clothes are washed in scent-reducing soaps, air dried, and then stored in air-tight containers. Inner layers are washed again after every use. Mid-layers, maybe once every three or four uses. Outer layers are just sprayed down with scent-reducers after each hunt, but not rewashed. And when it comes to hunting, every stand on my property is in a spreadsheet listing the best wind directions to hunt that stand. I live by that. Now some stands, where deer could come from anywhere, can be hunted under any wind, as deer are just as likely to be downwind as upwind. But some stands are watching a particular feature, and I don't hunt them when my scent would be blowing towards that feature, only away from it.
