Poor ventilation, constant moisture and damaged sealant can cause silicone sealant to become laden with black mould.

However, with an ongoing financial squeeze, many Britons don’t have the cash to spend on specialised mould-removal products.

With this in mind, bathroom and kitchen experts from Drench have shared a simple tip costing less than £1 to banish mould from bathroom sealant – baking soda.

Nancy Emery, a cleaning expert from Drench, said: “When it comes to tackling mould, there are a number of simple, affordable products you can use that may already be in your cupboards.”

Baking soda is a slightly abrasive deodoriser, which means it will remove any unpleasant mouldy smells while scrubbing away mould.

Nancy explained how baking soda can be used to banish mould from silicone sealant mould.

She said: “Silicone sealant can be a haven for mould due to its porosity and use in areas regularly exposed to water.

“Mould in silicone is not only an eyesore but it is also bad for your health. To remove it, rub together a paste of 250ml white vinegar and two to three teaspoons of baking soda into the affected areas.

“Ensure you’ve got a thick layer over the mould, leaving it to soak for around five minutes. Then, using a stiff-bristled brush, scrub the black mould away from the sealant.

“It is important to scrub firmly, but don’t be too rough, as silicone sealant is delicate. Finish with a cold, wet sponge to rinse.”

Britons may start noticing mould in their homes as the weather gets colder and wetter.

Some of the most common types of mould include black mould and blue and green mould.

Nancy explained: “Black mould commonly grows in small, dot-like clusters and can have a slightly unpleasant smell that accompanies it.

“While this type of mould can appear anywhere in the home, it is most common in the bathroom (where there is less ventilation), behind furniture and in corners of bedrooms.

“Not only is black mould unsightly, if left untreated, it can pose serious health problems from breathing in its spores.”

“Like black mould, blue and green mould usually grow in high moisture areas. Although they do not pose the same health risks to most people.”
