Dishwasher Powder

Bottom line: This powder dishwasher detergent performs only just OK overall, but it only costs 16¢ per wash. It's good at removing red wine stains and OK at removing coffee and minced-meat stains, but it's just OK at removing egg-yolk stains and baked-on cheese stains, and extremely poor at removing rice stains.

How we test

Overall score is the average of 6 scores for stain removal.

We test in a controlled lab environment using plates that are pre-stained. We get the plates from the same company that supplies consumer organisations and dishwasher manufacturers globally. We set the dishwasher to a standard cycle at 60°C and test each detergent 4 times. To see how well the detergents have cleaned the plates, we measure the reflectance with a spectrophotometer before and after cleaning.
