Yellow Stuff Starts Dripping Down Your Bathroom Walls? Here’s What It Might Be

Identifying the Yellow Stuff

So, back to my friend’s yellow dilemma. The yellow stuff dripping down could be several things:

Nicotine Residue: If previous occupants were smokers, nicotine stains are a possibility. These can seep through paint over time, especially in humid conditions.

Soap Scum and Hard Water Deposits: Regular splashes from soap and mineral-heavy water can leave behind yellowish stains as they accumulate.

Mold and Mildew: Yes, some molds can appear yellow, especially in their early stages.

Oxidized Paint: Occasionally, paint reacts with moisture and oxidizes, resulting in yellowish drips.
