A black light, available at Wal-Mart, Spencer Gifts, and many carpet cleaning supply (janitorial) houses, is a necessity for a good urine removal demo. The better the black light, the more successful the result. I use a Spectroline Model EA-160 from Spectronics Corporation, Westbury NY.
To use the black light, go to an area where there is suspected urine (restroom, mattress, patient room) and scan for white or yellow florescence.
Note: Other things glow as well and not all can be removed with OdoSolv. Odosolv removes the glow of urine because it removes the urine, not just the glow. Decaffeinated coffee, for instance will glow blue and permanently stains most fibers because of the dyes used to recolor coffee after the decaffeination process. Optical brighteners used in some carpet cleaning products (not OdoSolv-another selling point) will glow lavender (blue-white). These dyes cannot be removed with any substance. Over time, optical brighteners (dyes) oxidize and degrade turning yellow or completely removing color from the fabric it is used on.
Treat the area and gently scrub the area with your tamping (spotting) brush, then wait 4-5 minutes. Extract the area with fresh water and check for florescence. If stain is removed, but glow is still present repeat procedure but leave the OdoSolv on the area without extracting.
