I used to use baking soda but now I use Sport Wash. Just a capful (1 oz) does an entire load of my hunting clothing. Then, even though I hunt the wind, I alway use Scent Shield. And several times I had deer so close I could have almost reached out and touched them.
As for the orange thing. I only wear it when required. And I too have not noticed any difference in deer detecting it. And I only hunt public land where there is considerable pressure.
