<p>[QUOTE=&quot;desertgem, post: 748349, member: 15199&quot;]Almost all Laundry detergents and many dish detergents contain UV brighteners. Rinsing well should remove these from metal. Some hunters wash their outfits in special detergents with no UV brighteners as they feel this makes them blend in with the background. Also since insects respond to UV extremely well ( UV Kill lamps), a person who hates insects might find it advantageous to do the same.</p><p><br /></p><p>Oils, oil products such as certain coin cleaners and preservatives fluoresces in UV, as do secretions such as saliva, sweat, and &quot;more personal secretions&quot;.</p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
