Mold is a fungus that thrives in moist and damp environments, which is why it isn’t rare to find it on bathroom ceilings. Mold builds up on bathroom ceilings because the moisture from the shower produces high levels of humidity, which provides a breeding ground for this fungus to grow. The problem aggravates when the bathroom isn’t properly ventilated.

Apart from being unsightly, mold is also injurious to health and can cause permanent damage to your home. This is why it is important to remove mold spots on the bathroom ceiling. Below we have provided instructions on how to clean mold spots off bathroom ceiling and answered some common questions about the process.

How to Clean Mold Spots off Bathroom Ceiling – Instructions


Step 1: Open the Windows

Open the windows of the affected bathroom before you start cleaning the mold. Also, turn on the exhaust fan if you have one. This will keep the area ventilated and help remove the mold spores. Don’t open the door of the bathroom as mold spores could enter your home and aggravate the problem.

Step 2: Wash the Ceiling

Wash the ceiling with warm, soapy water and a rag. Mild laundry soap would work well. Then mix half cup of Trisodium Phosphate in two gallons of warm water. Dip a stiff scrub in this solution and then clean the ceiling with it. Allow the bathroom ceiling to dry.

Step 3: Create a Diluted Chlorine Solution

Add one part chlorine bleach to two parts of warm water into a bucket. Dip a rag into this solution and then wipe down the affected area of your ceiling with it. Rinse out the rag in the solution frequently while cleaning your ceiling. Leave the bleach to soak into the bathroom ceiling for a few minutes.

Step 4: Let the Bleach Sit

Wait for at least 10 minutes and then clean the ceiling with bleach one last time.

Step 5: Wash the Ceiling with Warm Water

Fill a bucket with warm water and use a rag to clean the bathroom ceiling to remove all traces of bleach.

Q.1) How to remove mildew from ceilings in bathrooms?

Mold and mildew can be removed in the same manner. If mildew has deposited on your bathroom ceiling, follow the instructions we have listed above to remove it, and prevent it from growing again in the future.

Q.2) How to prevent mold growth in your bathroom?

Mold spores grow in damp conditions. Showers produce steam, and that steam rises to the ceiling, providing a breeding ground to mold. To avoid mold from depositing on your ceiling again, keep the window of your bathroom open while taking a bath. If you don’t have an exhaust fan in your bathroom, consider installing it and keep it on when you are taking a shower to prevent humidity. You could also use a mold-resistant paint and cover the entire bathroom ceiling for protection.

Q.3) Should you always clean mold on your own?

You can clean the mold from your bathroom ceiling on your own if it isn’t affecting a large area. However, if you have a problem area over 10 sq. ft, call in a professional for mold removal. When mold starts creeping into the walls, a professional’s assistance is required. If you try to take on mold on your own, you could end up releasing spores into the rest of the property, creating an even bigger nuisance.

Q.4) When mold becomes an issue?

If you notice little white or black dots on your bathroom walls and ceiling and your bathroom is giving off a musty smell, there is a good chance that mold has grown behind your tiles or walls. Some types of mold release toxins and can lead to health issues.

When exposed to mold, you might suffer from several symptoms include headaches, nausea, fatigue, eye irritation, and lung irritation. If you suspect that mold is causing health issues, visit your doctor and bring in a professional mold exterminator to investigate and remove the mold. If the mold isn’t that serious, just follow the instructions we have provided to remove it from the bathroom ceiling.
