Why Bathrooms Are Prone to Stains and Drips

Bathrooms experience constant humidity and temperature changes. After a hot shower, warm steam fills the room and moisture collects on walls and ceilings.

If that moisture doesn’t dry quickly, it can:

• Pull residue from the paint
• Dissolve soap or mineral buildup
• Reveal old nicotine stains
• Encourage mold or mildew growth

Over time, this mixture can create yellowish or brown drips that slowly run down the walls.
