HOW LONG WILL FORENSIC SPRAY LAST ON SKIN / CLOTHING?
SmartWater will wear off gradually as skin exfoliates and will remain detectable for weeks, perhaps even months after the incident, even with excess cleaning or showering. Once the solution has dried it will not be in any way visible on the skin except under ultraviolet light – criminals won’t even know it’s there.
Similarly on clothing, SmartWater will not be visible except under ultra violet light, however the solution will remain on clothing permanently.
Our Laboratory Technicians only require a trace the size of a speck of dust to link an offender back to a crime scene.
