I did some research on this as well. What I found was some camo will "glow" more than others under a black light.. Especially faded camo that has seen repeated washing and drying.. So I don't dry my camo any more and I use the scent free/uv free detergent where I used to just use regular detergent.. I believe the deer can see UV light more than humans.. I mean how else can you explain the ability for them to run thru the woods in pitch black and not run into a tree..
.. Most of the modern camo companies have figured this out to.. So if your using name brand camo your probably OK..
