Atsko 1341 Sno Seal UV Killer SprayUVKiller blocks ultraviolet reflection and luminescence. For all fabric, camouflage, and blaze orange. One bottle will treat two sets of hunting clothes.The original UVKiller has changed how hunters think about camouflage. It has been proven that animals and birds have sensitivity to ultraviolet light and the 438nm shortblue wavelengths that humans are blind to. UVKiller absorbs UV wavelengths and thereby eliminates the blue glow caused by fabric dyes and detergents that contain UV brighteners.UV Killer eliminates the brighteners from your camouflage making your camouflage almost invisible to the keen eyes of deer and other game.First wash new or soiled garments in SportWash. Then spray on UVKiller. UVKiller absorbs the ultraviolet light and literally kills the bluewhite 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 UVKiller. It should be noted that a single washing in commercial detergents or fabric softeners will (while not removing the treatment) render the UVKiller useless by depositing new brightener dyes.Always wash treated clothes in SportWash.
