How To Get Rid Of Black Mould On Bathroom Sealant

How to Effectively Eliminate Black Mould on Bathroom Sealant

Black mould (also known as Aspergillus Niger) on bathroom sealant can be an unsightly and unhealthy problem. It can trigger allergies, respiratory issues, and other health concerns. Eliminating black mould from bathroom sealant requires a comprehensive approach involving proper cleaning, addressing the underlying causes, and ensuring adequate ventilation.

Identifying Black Mould on Sealant

Black mould on sealant typically manifests as dark, fuzzy, or slimy patches. These patches may appear along the bottom or sides of showers, bathtubs, and sinks. It can also grow beneath the sealant, causing the sealant to discolour and detach from the surface.

Effective Cleaning Methods

Bleach Solution

: Mix 1 cup of bleach with 1 gallon of water. Apply the solution to the mouldy area and let it sit for 15 minutes. Scrub the area with a stiff brush, rinse with water, and dry thoroughly. 2.

White Vinegar

: Undiluted white vinegar is a natural mould remover. Apply vinegar to the mouldy area and let it sit for 30 minutes. Scrub the area with a brush or sponge, then rinse with water and dry thoroughly. 3.

Hydrogen Peroxide

: Apply 3% hydrogen peroxide directly to the mouldy area. Let it bubble and foam for 10-15 minutes. Wipe the area clean with a damp cloth and dry thoroughly.

Addressing Underlying Causes

Once the mould is removed, it is crucial to identify and address the underlying cause to prevent recurrence: 1.

Moisture Control

: Excess moisture is the primary contributor to mould growth. Ensure proper ventilation by using exhaust fans or opening windows during showers. Consider installing a dehumidifier to reduce moisture levels. 2.

Cleaning Frequency

: Regular cleaning with mould-killing products can help prevent mould buildup. Clean bathroom surfaces, including sealant, at least once a week. 3.

Sealant Replacement

: In severe cases, the sealant may need to be replaced. Remove the old sealant and apply a new, high-quality sealant with antimicrobial properties.

Ensuring Adequate Ventilation

Exhaust Fan

: Install an exhaust fan in the bathroom that vents directly to the outside. Run the fan during and after showers to remove excess moisture. *

Open Windows

: When possible, open a window to allow fresh air to circulate and reduce humidity. *

Dehumidifier

: A dehumidifier can help remove moisture from the air, creating a less hospitable environment for mould growth.

Additional Tips

* Wear gloves and a face mask when cleaning mouldy areas. * Avoid using harsh chemicals or abrasive cleaners that can damage sealant. * Let the cleaning solution sit for the recommended amount of time for optimal effectiveness. * Rinse thoroughly with water after cleaning to remove any chemical residue. * Monitor the area regularly for signs of mould recurrence and address any issues promptly. By following these steps, you can effectively eliminate black mould on bathroom sealant and maintain a clean and healthy bathroom environment.
