Diversey General Purpose Handheld Plastic Flashlight - UV/Black

The VeriClean System is a comprehensive cleaning validation solution that includes the use of a fluorescent marking spray along with a UV/black light to allow the user to spray a small quantity of liquid onto a surface that will leave an invisible marker when dry. After the surface is cleaned, the user can use the black light to detect whether the mark was removed, and thus whether the surface was properly cleaned.
