A method for a smart-device comprising receiving a user selection of an icon on a display, initiating acquisition of a first image of a target surface using a camera in response to receiving the selection, directing power to an UV-LED disposed proximate to the camera, wherein the power is provided to the UV-LEDs for less than about 0.5 seconds, while power is provided to the UV-LED, initiating acquisition of a second image of a target surface using the camera, determining an image visually highlighting a contaminant on the target surface in response to the first and second images, determining an object type associated with the target surface, in response to the first image, determining geographic data, and storing the image, the object type, and the geographic data in a memory.
