If your washing machine smells, it's likely you need a washing machine cleaner to freshen it up. It makes sense – after all, we use our washing machines many times during the week, sometimes more than once a day, so it’s important to keep the insides fresh and free from mould, mildew and limescale.
There is a range of special washing machine cleaners on the market, ranging from liquid solutions to tablets that you add to the detergent drawer. Look for value for money with something that goes a long way as well as added benefits such as those that kill bacteria or protect the inner plastic parts to keep the washer working well for longer.

How to buy the best washing machine cleaner
By keeping the inside of the washing machine clean, you’ll benefit from an appliance that won’t break down every few years or need a new part, which in turn saves you money and hassle in the long term. Here's what to look for in a good washing machine cleaner.
Does it tackle limescale?
In order to keep your washing machine working properly, it’s important to clean the inside regularly. Not only does this deal with any unpleasant odours resulting from damp, mould and mildew, but it will also help prevent limescale build-up, the enemy of any appliance that uses water, especially if you live in a hard water area.
Does it tackle odours?
A good washing machine cleaner will tackle odours inside the appliance caused by soap scum, grease and grime from clothes, which will in turn leave your laundry smelling fresh.
Does it kill germs?
Look for a cleaner that doubles up, removing stinky odours as well as descaling, cleaning and helping to protect plastic inner workings and the drum itself makes sense. But some solutions are antibacterial, too, killing germs at the same time, while others can also be used in dishwashers.
