How to Clean Black Mold in the Shower on Silicone?

The white Silicone lining is often called ‘caulking.’ It is the line that fills the spaces between your bathtub and the wall, or showers, sinks, etc. 

How to Clean Black Mold

Black Mold often grows in this gap filled with silicone because the other substances around it are often smooth and frequently washed, removing any mold growth chances.


The easiest way to handle the mold issue is to spray white vinegar onto the affected areas and then wipe it off. Remember to distill the vinegar with a bit of water to not prove overly acidic to your surfaces.


White distilled vinegar is a powerful cleaning agent and is the safest chemical to use on mold-ridden surfaces. Vinegar is also environmentally beneficial since it does not leave any harmful side effects. If you are looking for an instant solution to mold, then vinegar is your go-to ingredient.

Remember to use protective gear such as gloves before handling mold. Do not allow it to touch your skin. If you cannot reach into fine cracks, use an old toothbrush to get in there, spray vinegar on it, and then clean the gap thoroughly.


Using bleach is another powerful way of driving mold away. It is a whitening agent and will kill off any bacteria or pathogens along with the mold. 


While handling bleach, you need to wear gloves not to touch it or even breathe in it. Bleach is highly toxic when ingested or inhaled.

In the case of showers and bathtubs, which regularly come in contact with our skin, we must avoid using bleach in any form. This is why our first recommendation is always vinegar. Use bleach only if the mold is too thick and vinegar is not working on it.

Toilet Paper

Yes, you read that right – toilet paper can clean mold too. Like any paper, it is thin and can be used with vinegar to curb mold growth. If you have severe mold issues, twist some toilet paper into a roll, dip it in vinegar and keep it on the affected area for some hours. If you constantly keep the toilet paper there, mold will not have an opening to grow.

How to Prevent Black Mold in the Bathroom?

Bathrooms are the best places for mold to thrive because they are constantly moist. To prevent decay from occurring in the first place, here are some things you can try:

Using Exhaust Fans

While you are in the bath or the shower, always keep the exhaust fan running to prevent the water from seeping in. The exhaust fan will prevent moisture from gathering and successfully ban mold spores from making a home there. Ensure that your exhaust fan stays on for at least ten minutes even after you have come out of the bath.


A dehumidifier is one of the best ways to prevent mold anywhere in the house. If your bathroom is too big or you don’t have an exhaust fan, then consider investing in a dehumidifier. The primary purpose of this device is to ensure your surroundings remain dry and the humidity levels stay low.

Soaking Water after Use

Another method to ensure that mold does not collect in your bathroom, then keep your bathroom door wide open. If needed, wipe down the surfaces with remaining water droplets such as tiles, sinks, etc., to ensure a dry environment. 

Vinegar sprays

Keep a bottle of vinegar spray in the bathroom to use after every bath and gently spray it on the areas where mold might gather. Let it be for a couple of hours, and then wipe it off.

Other Ways to Get Rid of Black Mold in Shower

Black Mold is a formidable opponent to beat. Even after cleaning up the mold constantly, you feel like it is not coming off of the silicone, which means you will have to opt for other methods.

One such method is using bleach along with baking soda. 

Even though bleach is hazardous, there is no way to avoid it if you deal with more significant mold issues. 

Remember to wear a mask and gloves when handling bleach, and take extra care not to let it touch your skin.

To treat the mold, take some bleach and baking soda until you achieve a thick consistency, almost like a paste. Use a delicate toothbrush or even a paintbrush to apply the paste on the moldy silicone caulk. Once you have covered that area, put some plastic wrap to prevent the paste from drying out. If the paste dries out, just spray some more bleach on top of the plastic wrap. After several hours, wipe off with a dry cloth and check the results. You can keep repeating this process until you see the mold getting lesser.
