How do you choose the dishwasher detergent you test?
We picked the top-selling brands of dishwasher detergents, that were nationally available. You'll often find differing pack sizes and scents. These have no impact on performance.
How long does dishwasher detergent last?
If you only run your dishwasher occasionally or take advantage of buying detergents in bulk, and are worried about the life of ingredients in these products, we checked with the top performers. Both stated a recommended life of two years.
Costs of dishwasher detergent
According to the ABS, around half of Australian households have a dishwasher. It's no surprise then that the dishwasher detergent market is quite large, and growing. The tablet form of the detergent is the most commonly used, offering greater convenience (especially with dissolvable wrappers) than powders, but also much more expensive - especially when bought in smaller packs. But its all more convenient than doing the washing up.
Your dishwasher detergent will be a significant portion of the running costs over the life of your dishwasher, so invest some thought into whether you need the premium product or something a little less expensive with a similar performance.
While we generally purchased the smaller packs for our tests, you can get larger packs for a more cost-effective amount per wash.
Our testers measure out the manufacturer recommended detergent dose, and use it to wash specially stained plates. We do four test runs in the dishwasher and average the results for each stain. Stain plates used include egg yolk, rice starch, baked on cheese, red wine, coffee and minced meat.
Using a spectrophotometer, which measures how much light reflects off the stain plates measure how much dirt is removed. These readings are more accurate than the human eye – differences of about 5% are noticeable.
