In addition to being unsightly, bathroom ceiling mold can cause permanent damage to your home and is a health hazard for you and your family. It can be caused by the warm temperature of the room, the humidity from baths and showers, low levels of natural light, and poor air circulation. If you see mold growing on your bathroom ceiling, it should be treated as soon as possible and removed for health and safety reasons, as some mold spores can increase the risk of serious health problems.

Step 1 - Examine Your Ceiling

Take a close and careful look at your bathroom ceiling to check for any green or black spots. These spots can range in size from small specks to large clusters. They can be found in one large, water-damaged area or they could be spread out over the entire ceiling. These spots indicate the growth of mold spores and must be removed.

Step 2 - Make the Mold Remover

Put on your rubber gloves. Fill a bucket with 1 gallon of hot water, 1/2 cup of bleach, and 1/3 cup of laundry soap. Combine the ingredients and mix with a disposable stick, being careful not to let any of the liquid spatter outside of the bucket. The bleach will effectively get rid of the mold, but it could also accidentally damage nearby materials.

Step 3 - Remove the Mold

Open a window in the bathroom to reduce the intensity of the fumes. Then place the step ladder below the area that needs to be cleaned. Immerse the scrubbing sponge in the cleaning solution. Carefully climb the step ladder and begin to scrub the area. Rinse the sponge in the solution as you work. Be careful not to overdo it, as too much solution could mean dripping, which could damage your unprotected skin or clothing. Examine your ceiling again to see if any spots still need to be treated. Continue the process until all of the mold has been removed.

Step 4 - Rinse the Ceiling

Squeeze out the sponge and carefully empty the bucket of the cleaning solution into a sink. Rinse the bucket and sponge with clean water. Refill the bucket with cool water and immerse the sponge in it. Climb the step ladder again and rinse the ceiling area with the water, patting the ceiling dry with a towel. Turn on the fan and allow it to circulate the air in the room for the next 30 minutes.

Step 5 - Prevent Further Mold

Mold spores will grow in damp, humid conditions. Showers and bathtubs tend to produce steam, which rises to the ceiling and settles there in poorly ventilated bathrooms. It is rare that a ceiling gets dried or that it is exposed to sunlight, so spores begin to grow. To avoid the accumulation of mold spores, it is vital to circulate the air when the shower or bath is being used, especially if the weather is hot and humid. Be sure to open any windows in the bathroom when you are showering, even if it is just slightly. A bathroom ceiling fan or room vent would reduce a great deal of the moisture in the room. Another solution would be to consider using a mold-resistant paint and covering the entire ceiling for protection.

Other ingredients that can be used to help include borax, tea tree oil, and baking soda.
