3. Keep the windows open

If you don’t have a fan installed in your bathroom, you can make do with what you have. The primary goal of the fan is to allow fresh air into the bathroom and reduce moisture and humidity.

Additionally, if you keep the bathroom windows open while having your bath and for about 30 minutes after each bath, moisture accumulation will be reduced as well.

The aeration will subsequently remove unwanted moisture and humidity from the bathroom, ensuring that mold growth will also be hampered.

4. Remove excess water

Water is the primary source of moisture in the bathroom. The accumulation of water after showering will subsequently cause mold when the water starts evaporating.

To prevent this, get rid of showering water or any other water in the bathroom immediately you are done showering or bathing. You can do this with a squeegee, an efficient tool for water removal.

Don’t leave the sink or tub wet too. Wipe them dry with the squeegee and reduce the possibility of moisture accumulation, and eventually, you will prevent mold from growing in the bathroom.

Once a week, clean the tub, shower, toilet, and sink and keep them as dry as you can. There are commercial cleaners that can assist you to get the desired result. Check your local or online stores for these cleaners and use them as instructed.

5. Fix all leaks

If there are leaks in the bathroom, that may serve as another channel through which mold can grow and thrive. Such leaks are usually the source of unwanted water in the bathroom.

A leaking pipe may pour in more water into the bathroom during water transportation while a leaking ceiling may conduct water into the bathroom through the ceiling as well, leading to wall and ceiling mold.

Thus, whenever you spot leaks in your bathroom, address the issue without delay. If you can personally fix the problem, go ahead and do it without waiting until much damage is done to your bathroom.

If you don’t have the skills to fix the problem, hire a professional plumber to fix it, that way, you reduce the amount of water and moisture in the bathroom. This will invariably reduce the humidity and slow down mold growth.

The sink and bath are not the only parts of the bathroom that should be kept dry. As a rule of thumb, the entire item in the bathroom should be kept water-free.

This is because whenever you are done with bathing, everything in the bathroom including the window(s), door, floor mats, and shower curtains are nothing but wet objects that will be the ideal place for mold to grow.

This highlights the significance of ensuring that all these pieces of furniture and other items in the bathroom should be kept clean. How do you go about this?

For a start, spread the towel on a line to keep it dry. A wet towel will promote mold growth. Cultivate the habit of washing your towels in hot water and then spread them in the open to dry fast.

Make sure that your shower curtains can easily be washed and kept dry, this overrules the use of plastic or vinyl shower curtains. Hemp, cotton, or nylon curtains will be great because they can be washed in hot water and dried as soon as possible.
