I also thought the product would be good until I went and bought a black light and tested my cloths that I have washed in un-scented Tide, etc. Non of the cloths glowed? I sprayed the UV Killer on one amo shirt, and the spray goo itself ACTUALLY GLOWED?

Go figure.
Anyothers have similar results?
Just could be the Tide I use, Unscented Skin Sensitive brand has no uv brightners for skin sensitive consumers? I would recommend testing your cloths first prior to spending so much money on the sprays, etc. $2.99 for black light! JIMO
