On white areas it picks up on splashes, presumably laced with bacteria from toilet aerosol after flushing. It also really shows up dust particles on darker areas. On the hands it does show up whiter patches though when I washed the areas they still remained. (must be skin pigmentation). Hope this helps. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Sc *by S***N on 18 March 2026* It killed germs and I had relief. After few moments enigma code got broken.
