Mould is just one of the many causes of stains on silicone sealants that are neglected in homes, particularly in bathrooms.

Silicone sealants around the shower and bath are typically the most prone to mould if they are not cleaned and wiped down regularly.

When mould and stains occur, Lina DaSilva from Toronto Shine Cleaning claimed that there’s no need to resort to chemical-filled products when there are home remedies on hand.

Speaking exclusively to Express.co.uk, Lina recalled the first time she encountered a mouldy silicone sealant. She said: “It was early in my career, and I was determined to tackle it without using harsh chemicals.

“It was a revelation to discover how simple household items could solve the problem effectively.”

For those struggling with stubborn mould stains that look like they won’t budge, Lina has recommended one particular product - hydrogen peroxide.

She said: “Hydrogen peroxide serves as a backup for stubborn mould. It’s a potent mould killer and can whiten the sealant.”

Hydrogen peroxide is a powerful cleaner, antibacterial, antifungal, antiviral, and natural bleaching agent. 

The common three percent solution found is potent enough to cut through most stains and grime and disinfect a range of surfaces and materials.

To use hydrogen peroxide on your silicone sealants, it is important to first wipe down the area as you want to remove any loose dirt or grime before getting into the deep cleaning. This step ensures that you're not just spreading dirt around during the cleaning process.

You want to remove any loose dirt or grime before getting into the deep cleaning. This step ensures that you're not just spreading dirt around during the cleaning process.

Next, fill a spray bottle with hydrogen peroxide (preferably three percent solution). Lightly mist it over the areas that still show signs of mould. Let it sit for about 20 minutes, and then scrub it with a soft-bristle brush. Rinse thoroughly with water.

For slight mould and stains, households can tackle the task with vinegar before going in with baking soda. Vinegar is a mild acid that not only “kills mould but also helps in breaking down soap scum or mineral deposits”. It's your go-to for tackling multiple issues at once.

Soak cotton balls or a cotton cloth strip in white vinegar. Place them directly on the silicone sealant, ensuring complete coverage. Let it sit for at least an hour to give the vinegar time to “work its magic”.

Baking soda acts as a gentle abrasive that can scour away persistent grime without damaging the sealant. When vinegar and baking soda combine, they create a fizzy reaction that further helps in lifting grime.

Mix baking soda with a bit of water to create a paste. Apply this paste over the vinegar-soaked sealant. Using a soft-bristle toothbrush, gently scrub along the sealant lines.

Whichever natural remedy you choose, ensure you are wiping down the sealant after cleaning and patting the area dry with a towel to prevent moisture buildup, which could lead to more mould.
