U-V-Killer blocks ultraviolet reflection and luminescence. For all fabric, camouflage and blaze orange. One bottle will treat two sets of hunting clothes. The original U-V-Killer and Sport-Wash Combo Pack has changed how hunters think about camouflage. It has been proven that animals and birds have sensitivity to ultraviolet light and the 438nm short-blue wavelengths that humans are blind to. U-V-Killer absorbs U-V wavelengths and thereby eliminates the blue glow caused by fabric dyes and detergents that contain U-V brighteners. U-V Killer and Sport-Wash are two revolutionary products which eliminate the brighteners from your camouflage. They make your camouflage almost invisible to the keen eyes of deer and other game. First wash new or soiled garments in Sport-Wash. Then spray on U-V-Killer. U-V-Killer absorbs the ultraviolet light and literally kills the blue-white glow which animals and birds so easily see on untreated garments. For a better chance at all wild game, treat your camouflage and blaze orange with U-V-Killer. It should be noted that a single washing in commercial detergents or fabric softeners will (while not removing the treatment) render the U-V-Killer useless by depositing new brightener dyes. Always wash treated clothes in Sport-Wash.

I used this and deer scent scrubbed them both in. (I’m using an invisibull3 blind from Gander Mountain, another great buy. Being 6’2″ no need to bend over.) I took the blind out on a hunt the next day set it up, within 3 hrs had a doe run up spotted her about 25 yards away with the wind towards the blind I was under a canopy of trees, blending the best I could with the surrounding area. She come trotting in then slowed to a walk then stopped looked around looked right at the blind no fear was in her. UV killer did the job. Thanks I hope this post helps you.

Soooo anyone with children or pets will tell you that any bodily fluid doesnβt come out of carpets. Had a landlord request a blacklight inspection because we have pets. I have a cat that is a jerk. I cleaned my carpets meticulously. There arenβt and visible stains or odors. Itβs perfect! Until you turned off the lights and shine a black light. Honestly, it could be worse, but any way you slice it Iβm not replacing the carpet when itβs in perfect condition by any other landlords standards. I spot treated, steam cleaned, ect – once it was dry I used this stuff and they disappeared as I was shining a light. I did a crap ton of research trying to find this stuff. Found a company used to make a similar product specifically for carpet that they stoped selling 10 years ago. Thanks to my research and the comment from the dad who reviewed this product I knew it was safe to use.On another note, for those worried about the next home renters. I actually sprayed this in the closet where my cat also sprayed, them spot treated and steam cleaned where I knew the stain was, and the product lasted through cleaning. Still no UV reflection. I will be suggesting this like a mad woman to anyone trying to solve this problem

Have used the product before. Got a bigger bottle this time. Have been within mere feet of deer and elk without them spooking. Of course I use extreme measures for scent covering also.

Look, I’ve tried this product 3 times over the last several years on snow camo. I keep looking for a quality pattern snow camo with a few sticks on it that’s UV dead, but I have yet to find a truly UV dead snow camo suit/shell. And so, out of desperation, I bought the large bottle of this product thinking I would just build up layers of sprayed applications and the result would be a UV deadness that would be near-enough-dead. Nope. Under a black light, you can make out the line defining where it was sprayed and where it wasn’t, but the human eye can distinguish something like 10,000 shades of white alone. Even with 4 coats of this stuff, my camo is still UV hot…it glows.The pant (on the left) was not sprayed at all. The top’s body (on the right) has one coat. The top’s sleeve has 4 coats. The fleece hat is naturally completely UV dead, the way I like it.Might work for cat and dog pee on carpeting (I wouldn’t know), but not on snow camo (for which it is designed).

Awesome product removes the glow just like it says if it helps I’m not sure I use it for coyote hunting not sure if coyotes see the same as deer but it’s Worth the effort to have a edge over game. But I did run into a few deer while I was in a wide open field and I stopped when I seen them and didn’t move they kinda looked at me but couldn’t make out what I was. Stayed still for about 2-5 mins they kept looking but still didn’t see me. My distance was 20-30 yards but my wind was blowing away from them so they couldn’t smell me. They ended up going on eating and slowly moving on then when I started to walk and move towards them they ran. I had no backdrop behind me I was skylined so they should of seen me plan as day but they didn’t so I going to say this product definitely works. Me and my brother had this on are clothing when we this happened he was 3ft next to me.

Since hunting clothing manufacturers doesnβt listen to their customers about manufacturing uv free clothing we have to rely on folks like those at Atsko to make a great product like their UV killer. Thank you Atsko.
