How to Choose a Washing Machine Cleaner

Washing machine cleaners are available in tablets, granules or liquid form, but the possibilities don’t just stop there. There’s also the option of built-in aromas or fragrance-free products. Below are some important considerations to keep in mind that will help you make the best choice.


Most washing machine cleaners have a neutral smell, but the option of a built-in aroma, such as lemon, is also available. Decide whether you prefer the solution to leave behind a scent or choose your own aroma by using fabric softener and washing detergent. 

Bear in mind that some cleaners can be quite pungent, and if it isn’t a smell you’re fond of, you might have to rinse the washing machine several times before this has been completely removed. 

Multi-Use Options

Would you prefer to get your money’s worth and use the washing machine cleaner on other gadgets in the kitchen, such as the dishwasher or coffee machine? Look for a multi-use product that will limit the number of detergents you have stored in the cupboards and will allow you to keep all kitchen appliances clean and odour-free.

Eco-Friendly Factors

There’s a mixture of eco-friendly and non-eco-friendly washing machine detergents on the market. Consider opting for a nontoxic and environmentally safe formula: in this case, it will not only protect your appliances, but it will also be safe for those with allergies.

Keep in mind how concentrated the formula is to make it more long-lasting and environmentally friendly. Also, inspect the packaging to see if it is recyclable. 

Germ Killers

Check what percentage of germs the cleaner is able to kill. The best ones will combat 99.9% of bacteria, helping to keep your appliance free from germs and hygienic for long-term use. Killing germs will also remove nasty odours and descale and clean the washing machine.

Alternatively, some formulas on the market simply remove a buildup of dirt and won’t kill bacteria, which isn’t as effective in preventing germ growth. 

Tablets or Liquid Form

Would you prefer a washing machine cleaner available in tablet or liquid form? The main difference is the application, as tablets already have the appropriate amount of detergent measured out. Alternatively, liquid allows you to adjust the dose, which might be practical if you want to increase or decrease the formula amount. 

Furthermore, how often would you need to apply the cleaner? Some manufacturers suggest adding it to every wash, whereas others are fine to use around every 30 washes.


We selected the Calgon 3-in-1 Washing Machine Water Softener as our Editor’s choice and overall winner. This product boasts an effective formula that helps to prolong your washing machine’s lifespan. It also protects against limescale and residue buildup while eliminating bad odours. You can add it to every wash for the best results, and it’s safe to use on all fabric types. Finally, it minimises energy consumption by cleaning the washing machine’s heating element.
