An expert has unveiled a remarkably simple and affordable mattress cleaning technique that can leave your bed fresh and odour-free in just minutes, using an ingredient costing as little as 89p. With rising spring temperatures drawing sweat and unpleasant smells to the surface, regular maintenance every few months is crucial for a hygienic sleep environment.
The Science Behind Mattress Odours
Martin Seeley, CEO of MattressNextDay, explains that mattresses naturally absorb small amounts of sweat and humidity from the air each night. "During winter months, this moisture tends to remain trapped because homes are less ventilated and beds stay covered for longer periods," he notes. "Over time, this gradual buildup inside the mattress fabric can lead to persistent odours and reduced freshness."
The 89p Solution: Bicarbonate of Soda
The expert recommends using bicarbonate of soda, commonly known as baking soda, as an effective odour absorber. This versatile household ingredient works by neutralising trapped smells within the mattress fibres. To implement this method, simply scatter the bicarbonate of soda evenly across the entire mattress surface and allow it to sit for 30 to 60 minutes.
After the waiting period, thoroughly remove the powder using a vacuum cleaner fitted with an upholstery attachment. Repeating this process every few months will help maintain a consistently clean and odour-free sleeping surface. Beyond its mattress applications, bicarbonate of soda serves numerous purposes around the home, making it an exceptionally cost-effective cleaning solution.
Additional Mattress Maintenance Strategies
Beyond the bicarbonate of soda treatment, several other practices can significantly extend your mattress's freshness and lifespan. The expert emphasises the importance of allowing your mattress to breathe daily. "One of the simplest recommendations I make is letting your mattress air out every morning," says Seeley. "If you make the bed immediately, you trap heat and moisture inside. However, leaving the duvet pulled back while you prepare for your day gives the mattress valuable time to dry out."
Maximising Air and Sunlight Exposure
When changing your bedding—which should occur weekly during warmer months—position your mattress near an open window or outside if possible. "Natural daylight and fresh air help dry out moisture that has accumulated in the mattress fibres," explains Seeley. "Sunlight creates a drier environment on the mattress surface, making it more difficult for odour-causing bacteria and dust mites to thrive. Even brief exposure to daylight while changing sheets can provide noticeable refreshing benefits."
Proper Mattress Rotation Practices
Regular rotation is another essential maintenance aspect. Experts advise rotating your mattress every three months to ensure even wear distribution. For memory foam and hybrid mattresses, rotation rather than flipping is typically recommended. Some traditional spring mattresses can be flipped if the manufacturer specifically advises this approach, though rotation generally remains the safer option for most modern mattress types.
By combining the bicarbonate of soda treatment with these additional maintenance strategies, you can effectively combat odours, extend your mattress's lifespan, and ensure a cleaner, more hygienic sleeping environment throughout the year.
