Hi guys 29 years in this game but didn't always have UV lights. What explanation do you offer (scientific or otherwise) as to why certain organic matter still "lights up" the day after treatments and cleaning? Thanks..

Because you're a terrible carpet cleaner. Just kidding.

Its actually due to a variety of reasons but just go the CSI route. Why can crime scrne investigators find blood afrernits been cleaned ?

The different elements and molecules that make up the stain will sometimes bond with the carpet filament (especially more worn carpet) there's no 100% guarantee to remove a blakcligt signature

Phosphors or phosphorus substances etch into the fibers and are usually what causes the glow. Pet urine and organic soils can leave these invisible stains that will glow even after cleaning. It wont go easily away. you can remove it but it require harsh chemistry
