If you are one of those who find the mold on your bathroom ceiling revolting to look at, then this article is for you.

In this article, we will show you how to get rid of mold on a bathroom ceiling step by step.

Supplies Needed To Remove Mold

It’s sometimes tough to completely get rid of mold. Often, cleaning it alone doesn’t work because the mold can grow back around the ceiling, so in addition to cleaning the area where the mold spots are, killing it is usually the best way to go.

In rare cases, the only solution might be to completely replace the ceiling to prevent the mold spores from growing again! 

Items you’ll need to start cleaning your bathroom ceiling’s mold issue:

  • Gloves
  • Warm water 
  • Cleaning detergent 
  • Cleaning tools 

Before you get started, it’s essential to remove any items from the bathroom that may reside on them, including:

  • Remove bathroom rugs, towels, and underwear
  • Close off all the available vents so that the mold spores will not be able to get to other parts of the house
  • Open up a window for proper airflow

Now we can begin the cleaning process. This part is relatively easy, as mold does not stick too hard to surfaces and comes off with ease.

With a soft-bristled brush, wash away the mold on your ceiling with a simple mix of detergent and water.

After doing this, wait for the area to dry for about 30-60 minutes.

Now, the mold should be visibly gone. But that’s not all. Because although cleaned, mold spores are still on your ceiling, even though you can’t see them.

So the next step will be to kill these mold spores to prevent later mold growth on your ceiling.

How To Kill Mold Spores

To kill mold spores, follow these steps:

  • Mix a quarter cup of bleach with a quart of water.
  • With a spray bottle, apply the solution to the affected area.
  • If you do not have a spray bottle, a sponge can work here as well.
  • Wait for 20 minutes and apply the solution a second time.
  • Finally, Allow the area to dry for another 20-30 minutes. 

When using bleach, it’s recommended to wear a shirt and shorts so that you don’t mind getting dirty. We recommend choosing old clothes so that you’re not worried about a bleach stain getting on your clothes.

Bleach can be very irritating, so don’t forget to open a window for airflow. 

Put on all protective gear, including gloves, face masks, and goggles, for eye protection, as earlier said. 

If you don’t have any bleach, another all-natural solution is to use vinegar. Vinegar can be found at your local supermarket and is just as effective on mold as bleach.

We recommend that vinegar is your best, cheapest option if you don’t have bleach readily available.

If you’re unable to find bleach around, vinegar may also be used to substitute for bleach.

Like how you applied the bleach to the mold on the bathroom ceiling, use the vinegar in the same manner. Once applied to the mold spots, let it sit for 30-60 minutes.
