Ok this is weird. In the bathroom of the new place I’m staying in, one wall has odd, dry “drips” that move very slowly downward over the course of days/weeks. It’s not paint texture. You can wipe them off but they slooowly drip down again. Nothing visible causing them. Above is dry & it’s not steam.
Ichor, obvs.
Is this after a shower?
The other walls in the room, same paint, same conditions, do not have this happening. It is very very odd but I’m hoping someone has an explanation I haven’t thought of. Oh & it was there when I moved in. I wiped it off and then it reappeared slowly, dripping down again, over the course of weeks.
Good thing this isn't a month known for horrifying surprises
If you're certain it isn't evaporated steam from the shower, mixed with a bit of dust to turn it brown, the other main possibility is "surfectant leaching"—the paint separating because of how it was first applied
Learn how to fix and prevent the appearance of paint streaks, spots or residue on painted surfaces known as surfactant leaching.
It’s gross. It’s body oil seeping out from the paint.
Probably a poltergeist.
It looks like condensation to me, if that makes any sense in context.
