Since moving into my apartment 2 years ago, I've periodically noticed little red spots and streaks appearing just about everywhere. I clean them when I can, but they are difficult to remove. Until recently the spots were limited to the walls, mainly in the bathroom. They always appear in groups, sometime looking like drips, sometimes like spots, and sometimes like splashes. They appear both low on the walls near the floor and high up near the ceilings, near windows and on iterior walls, in just about every room, sometimes behind appliances, sometimes near light switches, and now on my furniture! Today I noticed more on the wall in my living room, and, not to far away, a spray of them on the side of my computer monitor! They are orange/chocolate/rust in color. I cannot figure out whats causing them. When they appeared in the bathroom and under light switches I assumed it was rust stains from the humidity. Then when they appeared in the living room I guessed it might have been rust from pipes behind the walls. Now that I've found it on my computer monitor and other furniture, some of which is nowhere near a wall, I'm completely baffled. Anybody have any clues? It's almost creepy how baffling it is. I feel like Lady MacBeth cleaning phantom blood from everywhere!
