Stop 'musty' smell from building up in washing machines with simple £1 solution

If you've ever gone to hang the washing up and cringed at that acrid, musty odour wafting from the washing machine drum, you're certainly not alone. Foul smells in the washing machine are amongst the most common household issues, and countless people have no clue where the stench is originating from.

Professional plumber James Clarkson, who has worked on residential and commercial plumbing systems across the UK for over 15 years, said: "The smell usually comes from trapped detergent residue, fabric softener, and lint mixing with warm, damp conditions.

"This creates the perfect breeding ground for mould and bacteria. Once that builds up behind the drum or in the rubber seal, the machine can quicklystart smelling."

If you want to get your washing machinespotlessly clean, and prevent that revolting smell from developing there is a straightforward and incredibly affordable solution.

The expert recommends a simple £1 household staple: bicarbonate of soda (baking soda), reports the Express.

James said: "Baking soda is a natural deodoriser and mild abrasive.

"When you run it through the machine, it helps break down soap scum and neutralises odours without damaging the drum or pipes.

Most households already have a box in the kitchen cupboard, and it costs about a pound."

How to clean your washing machine with baking soda

• Add half a cup of baking soda directly into the drum.
• Run an empty hot wash cycle (60°C or higher).
• For extra freshness, add a splash of white vinegar in the detergent drawer to cut through limescale.
• This simple routine can be repeated once a month to keep odours at bay.

It's also crucial to maintain regular upkeep of your machine to prevent odours accumulating.

A simple way to keep stenches at bay is to ensure you ventilate your washing machine properly.

Avoid leaving damp laundry in the machine for extended periods, and ensure to leave the door slightly ajar after each wash to allow the drum to dry out.
