Best and worst dishwasher detergents

Our experts put Finish, Earth Choice, EcoStore, Fairy, Aldi and more to the test. Which detergents make dull dishes shine?

Last updated: 12 October 2021

Need to know

  • Our expert dishwasher testers rated 27 detergents to find which performed well and which should be avoided
  • A supermarket own-brand product was the best performer in our tests, beating premium brands that cost more than twice as much 
  • Earth Choice Dishwasher Powder Lemon Fresh was the worst performing detergent in our tests

Bargain lovers, we've got some good news for you: the best detergent for getting your dishes sparkling clean will only cost you 19 cents per wash! 

In our latest dishwasher detergent test, Aldi's Logix Platinum 18 in 1 Dishwashing Tablets Lemon beat premium products costing more than twice as much, proving that you can be hard on food stains while being gentle on your hip pocket. 

Our experts tested 27 products and rated their cleaning performance on food stains such as egg yolk, baked-on cheese, rice starch, red wine and bolognese sauce.  

You may notice that the top three performers are all tablets, while the bottom three are all powders.

"Dishwasher tablets make up over two-thirds of dishwasher detergent sales," says CHOICE dishwasher expert Ashley Iredale. "And although they cost more per wash, our tests show they generally perform better than cheaper powders and gels."

CHOICE tip: If you're finding that your dishwasher tablets aren't dissolving fully when you put them in the dispenser drawer, just put them loose in the bottom of your dishwasher before running the load. 

Best dishwasher detergents

First place: Aldi Logix Platinum 18 in 1 Dishwashing Tablets Lemon

  • CHOICE Expert Rating: 78%
  • Cost: 19c per wash

One of the cheapest tablets in our test, Aldi's Logix Platinum outperformed products costing more than twice as much – even beating out Finish's premium Powerball Quantum Ultimate Pro products which cost from 32 cents to $1.13 per wash. 

"The Aldi tablets that received first place were actually one of the cheapest detergents in our review, at just 19 cents per wash. This goes to show that price is no indicator of performance, and you don't always have to spend a lot of money to get a good result," says Ashley. 

"However, one of the Aldi powders that we tested received a place in the bottom three, so make sure you don't grab the wrong one at the supermarket."

Equal second: Finish Powerball Quantum Ultimate Pro 0% Tabs and Finish Powerball Quantum Ultimate Pro Tabs Lemon Sparkle

  • CHOICE Expert Rating: 76%
  • Cost: 42c per wash (0% Tabs); 43c per wash (Lemon Sparkle)

Coming in at more than double the price of the Aldi dishwasher tablets, you'd almost expect better results from these two Finish tablets – but they were outclassed by the cheaper brand. 

Still, 76% is a great score and these products did a fantastic job of cutting through cheese, egg yolk and minced meat.
