In terms of cleaning your washing machine, you have the choice of inserting a cleaner into the detergent tank or drum. The washing machine cleaners also come in the form of a tablet, liquid or powder that need to be used at a certain frequency or timeframe in order to keep the washing machine clean and prolong its life.

If you require a quick answer, the best washing machine cleaner is the Calgon Powerball Tabs, which are designed to be used with every wash. According to the brand, they aim to provide unbeatable limescale protection, long lasting freshness and prevent the build-up of dirt. However, if you require a more affordable option that doesn’t need to be used as often, the Dettol Anti Bacterial is the best alternative that can be poured into the detergent tank every two months.

To rate the washing machine cleaners within this article, we based our recommendations upon testing multiple cleaners in our own machine, plenty of research and a number of factors. Some of the factors that we took into consideration included the ease of use, effectiveness, scent left behind and value for money.

How We Rated The Cleaners

Washing machine cleaners have been a reoccurring purchase of ours for many years and we’ve tried and tested a variety from some of the best brands in the UK.

We personally prefer to use formulas (liquid or tablets) that are placed inside of the detergent tank of the machine but other people may have their own personal preference. As you can see in the photo of us testing the Dettol formula, it takes just a few seconds to pour it into the tank and its for this reason why we prefer to use it.

As well as our experience of testing a number of formulas, we also based our recommendations upon hours of research and multiple factors. Some of the factors that we took into consideration included the ease of use, effectiveness, scent left behind and value for money.
