How to Remove Mildew From Bathroom Ceiling

Have you ever wanted to take a long and relaxing shower but found that you couldn’t relax because there were patches of black mold all over your bathroom ceiling? If you answered yes, don’t worry! We’ve all experienced mold in our bathrooms at some point in our lives. 

Black mold often causes the infected area to smell musty and stale. It can also cause health problems, such as coughing or irritation in the nose and throat. 

In this article, we will take you through a detailed explanation of what causes mold, as well as a few quick and simple solutions that help you get rid of this irritating and harmful problem. We’re also going to walk you through what you need to do once you have finished cleaning the mold and how to control mold from growing on your bathroom ceiling. 

Let’s take a closer look. 

Causes of Black Mold on a Bathroom Ceiling

Black Mold on a Bathroom Ceiling

Here are the leading causes of black mold on a bathroom ceiling: 

  1. Moisture and condensation within your bathroom have no way to escape if the bathroom is poorly ventilated, causing mold to grow. 
  2. When you take a hot shower, steam rises and remains trapped under the ceiling. If you tend to keep your bathroom door closed after you shower, the steam turns into moisture that sticks to the bathroom ceiling. As a result, mold spores will start to grow. 
  3. If your bathroom doesn’t get a lot of natural light, this could further cause black mold to grow. The absence of natural light means that your bathroom cannot dry properly, which in turn means that the moisture in the air can’t escape.

It’s important to note that if the mold is spread across the entirety of your bathroom ceiling, then it would be best to hire a team of professionals to take care of the problem. However, if the mold is located in only one portion of your bathroom ceiling, then you can take care of it on your own. 

Here is a list of the equipment and materials that you will need: 

  • Safety gear 
  • Protective goggles or glasses
  • Rubber gloves 
  • A face mask (disposable surgical masks will do)
  • A bucket
  • A few spray bottles
  • A cleaning sponge
  • A scrubbing brush 
  • A clean and dry cloth 
  • Any container for measuring, such as a bowl or a cup
  • A ladder or a sturdy stool 
  • Bleach 
  • Liquid dishwashing soap
  • White vinegar, if you don’t have bleach 

Now, let’s take a closer look at removing mold from different types of ceilings. 

How to Remove Mold from a Tiled Ceiling: 

If you have a tiled ceiling, the mold is more likely to settle in between tiles instead of the grout. Therefore, you need to be prepared to do a lot of scrubbing! Here’s how you can get rid of it. 

  1. Put on your face mask, gloves, and goggles before handling the bleach. Bleach can irritate your skin if you’re not wearing protective gear, so make sure that you don’t touch it with your bare hands. 
  2. Combine 16 parts bleach with one part water, or roughly one cup of bleach with a gallon of water. If you don’t have bleach, you use plain white vinegar, but do not add any water.
  3. Distill the bleach and water solution or the plain white vinegar into your spray bottles. 
  4. Stand on the stool and spray the bleach solution or vinegar onto the infected areas. Don’t be stingy with the amount of bleach or vinegar that you spray, but take care to make sure that you’ve sprayed a large amount of the solution so that the grout is completely covered with bleach or vinegar. 
  5. Once you’ve sprayed a good amount of the bleach or vinegar solution, let it sit on the grout for 15 to 20 minutes. 
  6. After letting the bleach or vinegar sit for a while, use the scrubbing brush and firmly scrub between the tiles to remove the mold. Scrub the grout firmly and with force to ensure that you’re getting rid of all the mold. 
  7. If you cannot remove all the mold at one time, respray the grout or mold-infected areas with bleach or vinegar, and repeat steps five and six. 
  8. Once you’re satisfied that the mold has gone, do your best to rinse the bleach or vinegar away with water. 
  9. Dry the area with a clean piece of cloth. 

How to Remove Mold from a Painted Ceiling 

  1. Put on your protective gear, and wear clothes that you don’t mind getting bleach or mold spores on. 
  2. Combine one tablespoon of the dishwashing liquid with one cup of water and half a cup of bleach. Mix it well, then distill the mixture into a spray bottle. 
  3.  Spray the mold-infected parts of your ceiling with the mixture. 
  4. Ensure that you do not spray too much of this bleach and soap mixture to prevent the paint from getting damaged. 
  5. Let the ceiling dry. If there are no black spots remaining, you’ve successfully removed the mold. If black spots remain, respray the ceiling.

What to do After You Clean the Mold?
