What Causes Black Mold on a Bathroom Ceiling?

Mold on the ceiling is caused by moisture that has no where to go. Mold loves moisture. Steam from hot showers and bathtubs rises to the ceiling, and without proper ventilation it can settle there. If the moisture remains too long, mold spores begin to grow. In addition to being unsightly, mold can also cause health issues. According to the Centers for Disease Control and Prevention, mold can cause “nasal stuffiness, throat irritation, coughing or wheezing, eye irritation…or skin irritation.” And even more alarming, serious lung infections can occur in people with weak immune systems.

How to Clean Mold From a Bathroom Ceiling

  1. To clean mold from the ceiling, wash the affected area with a store-bought mold cleaner, or a mixture of dish soap and water. Let the area dry.
  2. Now it’s time to get out the big guns to kill the mold—bleach. Mix one-quarter cup of bleach with one quart of water and apply the solution with a spray bottle or sponge. Remember when working with bleach to crack a window for ventilation and wear gloves and eye protection. If you prefer to not use bleach, white vinegar can also be effective. Apply straight vinegar to the area with a spray bottle and allow it to sit for an hour, then wipe the area clean and allow it to dry.
