Platinum Plus All in One Lemon
We’ve put branded dishwasher tablets, including Fairy and Ecover, plus supermarket own-brand dishwasher tablets from the likes of Aldi, Lidl, Morrisons and Tesco 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.
Besides revealing our Best Buys, our results show how good each dishwasher tablet is at removing certain foods and drinks, keeping your glasses shiny and preventing cloudiness and watermarks from building up. You'll also unlock the results of our pricing research, where we analyse supermarket prices to reveal how you can save money on dishwasher tablets.
