Why should black mold in the bathroom be removed?
Black spots appearing on silicone gaskets or joints are not only a visual defect. They also pose a real health hazard, which should not be ignored. Mold in the bathroom most often appears in the shower cabin and around the bathtub, areas exposed to constant contact with water. Moisture and high temperature create a specific microclimate conducive to mold growth.
If you don't pay timely attention to the spots appearing on the silicone that accompany mold growth, you will have a significant problem. In a short time, the joints or gaskets will be covered with black mold, which has a negative impact on our health.

Home methods to remove mold on silicone
Sanitary silicone is an excellent solution for ensuring tightness between various connections. Unfortunately, it is also a great environment for mold growth, particularly in the bathroom, where there is high humidity and temperature. If you want to remove mold from silicone, you can use home methods.
Baking soda and hydrogen peroxide
Combine the powder with pharmacy-grade hydrogen peroxide (3%) in proportions to obtain a thick paste. Apply the prepared mixture to the black spots and leave it for about 15–20 minutes. The active oxygen produced during the reaction safely oxidizes the dark pigment of the mold. Gently clean the joint with a soft toothbrush after this time. Be careful not to scrub too aggressively—your goal is to remove the deposit, not to mechanically damage or tear the flexible silicone. Finally, rinse thoroughly with clean water.
Tea tree oil
It is a natural anti-fungal agent. Add it to baking soda, and then apply to the contaminated area. The action of the essential oil is not only a beautiful scent, it is a proven method to combat mold.
Distilled vinegar
A natural agent that can help when mold is developing rapidly. Pour it into a spray bottle. Spray the surface to remove the mold. Leave it for 30-60 minutes. Wipe the silicone with a dry cloth. Acetic acid effectively inhibits spore development, but does not remove the characteristic dark discolorations. To restore the silicone's snowy white shade, it is worth applying a homemade paste of baking soda and hydrogen peroxide (3%).
What to use to remove mold from silicone when home methods fail?
If home methods for removing mold do not work or you simply do not want to use baking soda, you can turn to more radical ways aimed at eliminating mold. The market offers a wide selection of products specifically designed to remove mold from silicone in the shower cabin. The use of specialized products from the professional chemistry range allows for quick handling of the problem. However, it should be remembered that agents based on concentrated sodium hypochlorite have a strong corrosive effect—application should always be carried out in rubber protective gloves and in a well-ventilated room.
- An effective agent for black mold on silicone should contain active chlorine in low concentration, sodium hypochlorite solutions, and enzymes breaking down the mold's structure.
- It is worth protecting hands with rubber gloves while using them.
- Apply the product to the moldy area, wait for the time specified on the package, and rinse it along with the mold with clean water.
What to do if the dark residue on the silicone in the shower cabin does not want to disappear?
