As homeowners, we strive to maintain a clean and healthy living environment. However, one persistent issue that many of us face is the growth of black mould on the silicone sealant in our bathrooms. Not only is this unsightly, but it can also pose health risks if left unaddressed.
In this article, we will discuss the causes of black mould growth on silicone sealant, provide DIY tips on removing unsightly mould, guide you on when to contact professionals for your mould problem, and share tips on keeping your silicone sealant clean and mould-free.
Black mould, usually associated with the characteristic growth of Stachybotrys chartarum colony, like any other mould, thrives in damp and humid environments. Bathrooms, with their constant exposure to water and steam, provide the perfect breeding ground for mould to grow.
What's more, silicone sealant, commonly used to seal gaps and joints around sinks, bathtubs, and showers, can become a prime location for mould due to its porous nature. Moisture can penetrate the silicone and create an environment conducive to mould growth.
One of the main culprits behind having a mouldy sealant is poor ventilation. When bathrooms lack proper ventilation systems, moisture tends to linger in the air, settling on surfaces and encouraging mould growth. Water leaks or condensation can also occur behind tiles or in wall cavities, leading to hidden pockets of moisture that contribute to mould formation on the silicone sealant.
If you spot black mould on your silicone sealant, it's important to take immediate action to prevent further growth and eliminate any health risks. Here are some DIY tips to effectively remove mould from silicone sealant:
Safety should always be a top priority when dealing with mould removal. Before starting the process, it is crucial to protect yourself by wearing appropriate protective gear. This includes rubber gloves, goggles, and a mask.
Rubber gloves are necessary to prevent direct contact with the mould and its spores, as they can cause skin irritation and allergic reactions. Goggles protect your eyes from any splashes or airborne particles that may be released during the cleaning process.
A mask is essential to avoid inhaling the lingering mould spores, which can lead to respiratory problems. Make sure to use a mask specifically designed to filter out small particles, such as an N95 respirator.
When removing mould from silicone sealant, preparing a cleaning solution is an important step. One effective cleaning solution can be created by mixing equal parts of white vinegar and water in a spray bottle. Vinegar is a natural mould killer that does not contain harmful chemicals. It's a safe and effective option for removing mould from silicone sealant.
Another alternative to vinegar is baking soda, which is also known for its mould removal properties. Baking soda is a good cleaning agent to remove mould from silicone sealant because it's a mild abrasive that helps break down the mould and remove stains without damaging the sealant. To prepare a cleaning solution using baking soda, mix equal parts of baking soda and water in a bowl to create a paste-like consistency.

Spray the cleaning solution generously onto the mouldy silicone sealant and let it sit for 15-20 minutes. Then, using a stiff-bristled brush, wet sponge, an old toothbrush, or a damp cloth, gently scrub the mouldy areas vigorously to loosen the mould. In the absence of these tools, you may also use toilet paper to do the job.
Rinse and dry: Rinse the silicone sealant with clean water to remove any residue after scrubbing. Dry the area thoroughly using a clean towel or cloth. It's crucial to eliminate all moisture to prevent mould from returning.
Try using a mould-resistant sealant: To prevent mould growth, apply a silicone mould-resistant sealant over the cleaned area. This will create a barrier and make it more difficult for mould to take hold in the future.
In some cases, the mould infestation may be severe, or the silicone sealant may be old and deteriorating. In such situations, it may be necessary to replace the silicone sealant entirely. Here's a step-by-step guide to replacing silicone sealant:
