Moldy bathrooms – Tips to remove mold

removing mold from bathroom
Molds are undesirable in our bathrooms since they stain the walls, they degrade our house and cause a bad smell and unbearable humidity.

However, the reason why we should worry more to eliminate mildew stain is linked to health problems.

In fact, molds such as Aspergillus, Alternaria, Acremonium, Cladosporium, dreschslera, epiccocum, Penicillium, Stachybotrys, Trichoderma, etc. produce allergens (substances that cause allergic reactions), irritants, and in some cases potentially toxic substances (mycotoxins).

Inhalation or contact with mold spores or mold may cause allergic reactions in sensitive people. Allergic reactions can include sneezing, runny nose, red eyes and a rash (dermatitis).

How to remove mold that grow in the bathroom? Here is a list of 10 tips and tricks. In this article we will talk about 3 household products that are of great help to destroy fungi and spores: baking soda, bleach and ammonia.

In subsequent articles, we will mention the benefits of vinegar, borax, hydrogen peroxide, essential oil of tea tree and grapefruit seed extracts.

Baking soda is well known as a natural cleanser and safe. A good trick to remove and eliminate mold in your bathroom or elsewhere in the house is to use baking soda.

Unlike other chemicals used to get rid of fungi, baking soda has a pH “soft” 8.1 and is safe for your family and your pets.

Baking soda has these three valuable properties: It destroys the mold, it eliminates the strong musty smell and it absorbs environmental humidity which is partly responsible for their development.

How to remove mold with baking soda?

Add a quarter of a teaspoon of baking soda in a spray bottle filled with water. Shake the bottle to dissolve the baking soda in the water. Spray the area covered mold with this solution.

Then use a sponge or brush to make sure to remove all the mold on the surface of the wall, the ceiling, a tile joint, a shower curtain, a cupboard or cabinet . Rinse the surface with water to remove residual mold on the surface.

Spray again the same surface and leave to dry. This will kill the fungi that remain in place and prevent them to grow again.


Bleach virtually destroyed all the species of indoor mold and the spores, leaving a disinfected surface resistant to the growth of new mold thereafter. Unfortunately, the use of bleach is only effective if the mold is growing on non-porous materials such as tiles, bathtubs, or glass. Bleach can not penetrate into porous surfaces such as wood and plaster.

How to remove and get rid of the mold with bleach?

Before handling bleach, be sure to ventilate the bathroom and put on rubber gloves to protect your hands. Mix the contents of one cup of bleach in a quart of water (approximately 1 part of chlorinated water to 10 parts water). The solution should be applied to smooth surfaces using a spray or sponge. It is not necessary to rinse the surface so that the anti-mold effect of bleach persists.

Another drawback of domestic use of bleach is that it can damage the materials where it is applied as it is a corrosive chemical.

Like bleach, ammonia destroys mold on hard, nonporous surfaces, but it is not effective to kill mold on porous materials like wood or plaster. Another disadvantage of the use of ammonia is that it is an aggressive and toxic chemicals.

Make sure you never mix ammonia with bleach because the combination of the two liquids produces a very toxic gas. The bleach mixed with ammonia was even used as a chemical weapon during World War II.

How to remove mold with ammonia?

In a spray, make a 50% ammonia solution (half and half pure ammonia water) prior to the spray of places covered in fungus. Exit the bathroom or shower and do not come back until an hour or two to avoid breathing toxic gases. Then rinse and clean.
