I use the Sport Wash on all my hunting clothing, down vests and sleeping bag, etc. to wash out the regular laundry UV-brighteners. Hand washing is good, let the item soak for about 30 minutes, then hand agitate, rise well, and let air dry.
If there is still a UV glow, then spray on the UV-Killer product.
I'd recommend using a black light first to see if in fact there is a UV problem. The Atsko special on the UV detector kit with free shipping is a real bargain ... you can easily spend twice the amount or much more for a black light.
