I don’t have no science to back me up , but this has been my experience
Skme years ago I was reading up on deer vision
Supposedly they pick up ultra violet light very well
So looking into it , it seems that most clothes give off a ultra violet light or reflection
Especially the ones washed in color brightner detergent
So I found out about this spray on that kills the ultra violet light
You can also get it as a detergent too
So I laid my camo out and sprayed both sides thoroughly . Hung it across fence and put it on next morning
I am very skeptical about gadgets , scents , and such
But like scotts308 have been busted many times setting very still and sometimes at distances
So late in the evening I was setting back under a holly tree that had some low limbs on it
A 5 point came through , stopped in front of me just looking around
It’s gaze crossed right over me
When it looked back over its shoulder I took the shot and got him
So now I got one positive effect from it
Which don’t hold much water with me
Couple more times I had deer walk right up to me either on the ground
So as years went on I gained confidence in the stuff and use it regularly
I have been busted a few times using it , but it definitely doesn’t happen often anymore
Supposedly you can get the same effect by simply using detergent without color brightners in it
But I continue to use the uv killer spray and kill the hell out of deer
Just my experience

And yes, they are a buisness, and they do design camo to attract the human eye and supposedly some of it I’d high in UV light spectrum
I don't use any detergents when washing my camo.
Washing machines were designed to be used without 'soap/detergent', that is why they have the agitate cycle.
