What are the best washing machine cleaners to buy?

We think the best washing machine cleaner you can buy is the Calgon Washing Machine Tablets 2 in 1, as they not only clean inside the appliance but help to protect the drum and any plastic parts from limescale build-up, too. We also think the Dettol Washing Machine Cleaner in lemon is worth buying, as it kills 99.9% of bacteria and also acts to remove limescale inside the machine.

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.

Alternatives to washing machine cleaner

All of the washing machine cleaners on our list will do a good job of cleaning your appliances. Having said that, there's plenty of room to experiment with DIY washing machine cleaners.
