You all know that household bleach causes Lumisol to glow too right? So do other chemicals and metals. I mean, not knowing that would make you 'ignorant' of how Lumisol works so you all knew that. My bad.
I mean, the idea that the walls in a clinic would *possibly* be washed with something like *bleach* is so *remote*...
Nah, it must be blood, right?

Washing drywall with bleach would be rather dumb.
