Not to try and sound like an arse but if you are going to test it and post it then you should probably follow their directions.

You aren't suppose to wash it in a UV brightning detergent (Tide)before you apply the UV killer.

If you read the directions it is a two step process. First youmust wash your clothes in sport wash and then apply the UV killer to eleminate any remaining UV brightners.




: First wash garment in Sport-Wash. Scent-Free Sport-Wash rinses 100% removing all traces of old soap residue, grease, oil, dirt, and sizing that would prevent U-V-Killer from forming a bond with the fabric. Other soaps do not rinse out and they leave behind residue. Sport-Wash is safe for all fabrics and dyes.

Spray Dry Garments. Spray till surface is covered. Imagine you are applying a color and don't want the former color to show thru. Brushing with a small brush will make coverage more uniform. A ultraviolet (UV) light can reveal "missed" spots even while U-V-Killer is still wet. U-V-Killer extends the life of fabric five times from sun rot.

Treated garments may be worn when completely dry, but 72 hours of adequate ventilation is required for the bond to reach full durability and for the garment to be scent free. Re-washing, waterproofing, and cover scent applications should be delayed for this 72 hours. The U-V-Killer treatment is designed to be permanent, and on most fabrics it will endure for the life of the garment.

A single washing in commercial detergents, fabric softeners, and or "Color Safe" bleach (while not removing the treatment) will render the U-V-Killer useless by depositing new brightener dyes on top of it.

Always wash a load of non-hunting clothes in Sport-Wash prior to washing your treated camo & blaze orange in order to remove residual brighteners from your washer and dryer. It is recommended that you confirm the absence of brighteners each season using a UV light.
