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

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. 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.

Think of mildew as mold’s less threatening cousin. They’re both fungi, but mildew is not as invasive and is easier to clean because it only lives on the surface. Mildew is usually light gray or white in color and has a flat, powdery appearance. To clean it from your bathroom ceiling, simply wipe it with a damp cloth sprayed with any household cleaner. You can use a bathroom cleaner specially formulated to clean mildew, or white vinegar will also do the trick. Fill a spray bottle with equal parts vinegar and water, spray the mildew, and wipe away.

Here’s how to use essential oils to get rid of that mildew smell.

How to Clean Mold in the Shower or Bath

Cleaning mold from the shower or bath can be done with the same methods used on the ceiling. Clean the area with a household bathroom cleaner first, then use either a bleach solution or vinegar to kill the mold. To prevent mold from growing in the shower or bath again, keep the bathroom ventilated and control moisture as much as possible. Use a bathroom exhaust fan, crack a window when showering, and make sure to wipe away any leftover moisture with a squeegee. Take further measures by keeping a spray bottle full of vinegar in the bathroom, spray your bath and shower after use to prevent mold growth.

Psst! Now that you know how to clean black spots in the bathroom—prevent mold and mildew from growing back with an exhaust fan. Here’s how to clean your bathroom exhaust fan to ensure it’s running properly.
