Some interesting things can be found on a bathroom wall. Numbers are written to “call for a good time.” Sometimes one can find an inspirational or uplifting quote, art, and murals. Alternately, there’s an undesirable or repulsive yellow substance that drips from time to time. However, few people know what that substance is, or how to get rid of it.It’s common to move into a new place and notice small things that need tending to like little places needing a paint touch-up or drawers that could use some WD-40. However, something much more serious also lies in waiting to be discovered. One woman turned to Reddit for advice after she moved into a new place and discovered yellow drips coming down the bathroom wall. Interestingly, there are several reasons for this strange and unappealing phenomenon.

“Recently moved in here and keep noticing these yellow marks dripping down the walls. It also sticks my organizers to my bathroom sinks and leaves marks. Does anybody know what this is?” She questioned. “This bathroom in general was pretty gross when I moved in I’ve tried to clean but the paint is coming off in a lot of parts of it too. Any tips would be amazing!”One person explained: “That’s called surfactant leaching. Usually happens in spots with more moisture, such as bathrooms. It wipes off pretty easily.”Meanwhile, another shared: “It will stop with time, sometimes days, sometimes months, but it will stop. Persevere and just keep wiping it off (no chemicals needed, just wipe while humid).”Lastly, a person suggested using a mixture of ammonia and water to get rid of the unwanted drips on the bathroom walls.
