The original two great products in one combo pack with an updated label design.
U-V-Killer ZERO 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 ZERO and ZERO Sport-Wash Laundry Detergent 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. ZERO U-V-Killer absorbs U-V wavelengths and thereby eliminates the blue glow caused by fabric dyes and detergents that contain U-V brighteners.

ZERO U-V Killer and ZERO Sport-Wash Laundry Detergent 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 ZERO U-V-Killer. ZERO 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 ZERO 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 ZERO U-V-Killer useless by depositing new brightener dyes.

Always wash ZERO U-V-Killer treated clothes in ZERO Sport-Wash Laundry Detergent.
