Scottyluck - I experimented with UV Killer from Atsko some years ago on other UV brightened camo that I owned at the time with poor results under a black light. While there is some reduction, it is not dramatic. Maybe its personal preference, Id just rather that the brighteners not be in the actual garment in the first place.
Dukkllr is right on with his military camo. Genuine military camo is UV neutral and will not glow under a black light. But I have found the military ripstop fabric to be noisy compared to the softer, quieter fabrics of commercial designs.
Jeff G I havent heard of 20 Muleteam Borax. I this something readily available at WalMart or the grocery store? Is it scent free?
