Full dishwasher detergent test results
By Patrick Gallagher
We’ve rounded up the results of our tough dishwasher tablets test to help you choose the best dishwasher tablets for your dishes, glasses – and budget.
Simply want to know which all-in-one dishwasher detergents will lift even the toughest dried-on food without leaving watermarks? Go directly to our best dishwasher tablets.
We’ve put branded dishwasher tablets, including Fairy, Finish and Ecover, plus supermarket own-brand dishwasher tablets from the likes of Aldi, Lidl, Morrisons and Sainsbury's through our tough lab tests. This means we can tell you which dishwasher detergents are the best – and the worst.
Put one of the very best dishwasher tablets in your dishwasher and your dirty plates, pots and glasses will show no traces of last night’s dinner. They'll also be shiny and watermark-free when you take them out of the machine. But our tests have also revealed dishwasher tablets that will leave your dishes stained, so you'll have to redo them by hand, and turn your glasses cloudy over time.
No one else tests like Which? – our independent lab tests recreate the tough dried-on food and drink you put in your dishwasher. So you can be confident that our Best Buy dishwasher tablets will get your crockery clean and shiny.
You might be surprised by our results – the priciest cleaning products aren’t necessarily the best. Save money with Which?, as we reveal the great value dishwasher tablets that are a Best Buy and cost a third of the amount per wash of the priciest on test.
