IT SEEMS like mould can get just about anywhere in your home, and experts have revealed that even your washing machine isn’t immune. But with research showing the average load of washing contains around 100 million E. coli ensuring your machine is cleaned properly is essential for your health.

That's why expert Arun Bhatoye has detailed how to keep washing machines as free of bacteria as possible and prevent the build-up of mould. “Washing machine seals are prone to mould growth due to the damp environment they are constantly exposed to,” he tells Hisense UK.
“The seal traps moisture and detergent residues, creating an ideal breeding ground for mould and mildew, especially if the washing machine is not regularly aired out or if low-temperature washes are frequently used, which may not effectively kill mould spores.”.
However, while mould is easily built up Arun says it is also easily banished from your machine. “Prepare a cleaning solution by mixing equal parts of white vinegar and water,” he says. “Wipe down the seal with this mixture to break down the mould. For stubborn patches, sprinkle baking soda directly onto the seal and scrub with a toothbrush.
“For severe mould, use a bleach solution (one part bleach to four parts water) to disinfect the area. Be sure to wear gloves and ensure the room is well-ventilated. Apply the solution, let it sit for 10-15 minutes, and then scrub with a brush before wiping clean with a damp cloth.
“After cleaning, run an empty hot wash cycle (at 60˚C) with a cup of vinegar or a specialised washing machine cleaner to remove any lingering mould and odours.”. When it comes to preventing mould, Arun says it’s important to take a few simple steps after each load.
“After each wash, leave the washing machine door slightly ajar to allow the seal to dry out,” he advises. “Wipe down the seal after every few washes to remove any water or detergent residue. Again, running a monthly empty hot cycle with a washing machine cleaner will help prevent mould build-up.
“Opt for high-efficiency detergents that leave fewer residues, reducing the likelihood of mould growth.”. Arun shares some top tips on how to keep your machine in good nick... He says: "During winter, washing machines generally face more challenges than in the hotter months, with their water supply are exposed to the cold.
"Pipes or hoses connected to outdoor taps are particularly at risk of freezing, which could cause ruptures or water damage. “Insulating these components or relocating your washer into a heated room can help prevent such issues. "Winter often brings bulkier loads like coats, blankets, and towels, so be mindful of distributing laundry evenly in the drum. This reduces strain on the motor and helps avoid imbalances during the spin cycle.”.
