We’ve discovered a supermarket own-brand dishwasher tablet that will leave your dishes sparkling for less than a quarter of the price of the most expensive branded products.
Our latest dishwasher detergent tests found just one Best Buy, which scored top marks for overall cleaning. But while the most expensive dishwasher tablets on test will set you back more than 30p per tablet, the supermarket own-brand Best Buy costs less than 12p per wash.
We’ve tested 10 all-in-one dishwasher tablets from big brands – including Ecover, Fairy and Finish – and major supermarkets, putting each tablet through tough tests to separate those that will leave your dishes sparkling from the ones best left on the shelf.
A low-scoring dishwasher tablet will leave you having to wash your dishes again by hand. Save yourself time – click to reveal our Best Buy dishwasher tablets.
Great dishwasher tablet savings
With some tablets costing as much as 32p per wash, dishwasher detergent may well be the most expensive cleaning product in your shopping trolley. However, you can save money without compromising on cleaning power. Our tests revealed a great-value Best Buy dishwasher tablet that costs less than a quarter of the price of the most expensive option.
If you run your dishwasher four times a week, that could mean a saving of £50 across the year. Read all of our dishwasher tablet reviews to see which ones will save you money, which ones are worth spending a little more on, and which ones are best to avoid.
Our tough tests
We test dishwasher tablets’ ability to remove everyday food and drink stains, including burnt-on milk, tea stains and egg, as well as scrutinising how much film builds up on dishes after multiple washes, leaving them looking dull. We also check for spots and watermarks left on crockery and glasses.
Below, you can see how a Don’t Buy dishwasher tablet fares against a Best Buy when tasked with removing tough tea stains from a mug.
We also test for grease removal, in order to separate out the cleaners that can tackle the dirtiest roasting tins and casserole dishes.
We make up a blend of peanut oil and lard, which is mixed with albumin (a protein found in egg whites) to imitate the types of greasy stains you’ll find in an everyday kitchen. This is then spread evenly across a set of metal tiles, which we wash in a dishwasher alongside cups, plates and glasses. We weigh the tiles before and after the cycle to see precisely how much tough grease has been removed.
Our bargain Best Buy managed to remove all of this tough grease, scoring full marks and an impressive maximum five stars for this part of the test. For all the details of our rigorous tests, find out how we test dishwasher tablets.
