I had a blacklight and figured I'd check mine. About half my clothes were uv free. Seemed like the cheaper cotton shirts and jeans all had uv but I don't wear them really anyhow.. My orange for gun season had uv as well, it already glows though.. lol

I did try the uv killer. Followed instructions but it diddn't seem to work. I mean maybe it dimmed it a bit but not much. I was more curious, but either way.. There ya have it...
