If your bathroom is prone to mildew infestation, you may be curious about how to clean it off. Don't worry; cleaning a mildew-laden ceiling is actually a very simple task.

Step 1 - Make Your Preparations

Before proceeding to clean, you will need to make a few preparations. First off, make sure you have a stepladder that is tall enough to give you comfortable access to your bathroom ceiling. Secondly, make sure to open your bathroom door and windows to ensure proper ventilation. This will help protect you from the adverse effects of prolonged exposure to the fumes emitted by the commercial mildew cleaner you'll be using. Lastly, take care to don a pair of safety goggles and possibly even a breathing mask, as dripping is sure to occur whenever a cleaning solution is applied to a ceiling.

Step 2 - Apply Your Cleaner

Having made the necessary preparations, you are ready to apply your cleaner. Step up on your ladder and vigorously spray your cleaner onto any mildew-infested areas. Make an effort to use only as much as you need to steer clear of any dripping. Leave the cleaner to soak into the mildew for several minutes.

Step 3 - Scrub Your Ceiling

Now that your cleaner has had ample time to sit, you are ready to scrub up the mildew growth. For most types, this task can be performed with the aid of a sponge or washcloth. However, if the mildew is particularly stubborn, you may need to use a hard-bristled scrub brush to successfully purge it. Additionally, if the mildew has found its way into the spaces between your ceiling tiles, an expendable toothbrush can be a surprisingly effective tool in scrubbing it away.

You can also stand on the floor and use a long-handled mop for scrubbing your ceiling if standing on a stepladder is problematic for you. Assuming the mildew deposits aren't very stubborn, this handy cleaning tool should adequately remove them.

When cleaning mildew, make a point of taking periodic breaks, especially if you feel yourself becoming overwhelmed by the cleaner fumes. It is recommended that you take these breaks outdoors, in the fresh air.

Step 4 - Apply Your Finishing Touches

Once you've gotten rid of your mildew deposits, you'll need to dry the ceiling with the aid of a clean, dry cloth. Moisture and dampness are among the leading causes of mildew formation, so when performing this step, be as thorough as possible.

To prevent future mildew infestation, make sure your bathroom is properly ventilated. This is usually a simple matter of installing a window-mounted electric fan in one of your bathroom windows and leaving the bathroom door open whenever your shower is in use.
