Dishwasher cleaner tablets: how do they compare with bottles?

Finish In-Wash Dishwasher Machine Cleaner is listed as three 17 g tablets. At the lowest displayed price of £4.75, the pack costs about £1.58 per treatment. This is a pre-measured tablet format, whereas the liquid products in the table use a 250 ml bottle.

Finish’s bottle instructions specify an empty dishwasher, the label removed, the cap left on and the bottle placed upside down in the lower basket. The machine is then run on an empty programme at a minimum of 65°C without ordinary dishwasher detergent.

Ordinary dishwasher tablets are different from dishwasher machine-cleaning products. Aldi’s Magnum Triple Chamber Dishwasher Tablets are listed as tablets for washing dishes, not as a separate dishwasher-cleaning treatment.

How to deep clean a dishwasher

A deep clean combines manual maintenance with an empty hot cleaning cycle:

  1. Empty the dishwasher. Remove dishes and loose debris.
  2. Clean the filter. Which? recommends cleaning it every month.
  3. Wipe the seals and door edges. Do this monthly, or weekly if the dishwasher is used frequently.
  4. Clean the spray arms. Which? recommends cleaning them approximately every three months.
  5. Run a dedicated cleaner. Finish specifies at least 65°C for its bottle, while Dr. Beckmann specifies at least 60°C.
  6. Repeat the hot cleaning cycle. Which? recommends an empty hot cleaning run about every six months, while Finish and Dr. Beckmann give more frequent intervals for their products.

Dishwasher salt and rinse aid have different functions. Salt helps reduce limescale by softening the water, while rinse aid helps dishes dry without streaks. Neither is a substitute for a dedicated machine-cleaning treatment.

Is dishwasher cleaner worth using?

Which? recommends using a dedicated dishwasher cleaner during an empty, hot cleaning run about every six months. Finish recommends approximately every three months for its cleaner, and Dr. Beckmann recommends every one to two months depending on usage.

A dedicated cleaner addresses the empty-machine cleaning cycle, while the filter, door seals and spray arms still require manual cleaning.

Can you use vinegar in a dishwasher?

Which? advises against white wine vinegar in a dishwasher because repeated exposure can affect stainless steel, door seals, the pump and drain pipes. Which? also advises against lemon juice, bleach and other strong cleaning products because they can damage seals and components.

Frequently asked questions

What is the best thing to clean a dishwasher with?

Use a dedicated dishwasher cleaner during an empty hot cycle, alongside manual cleaning of the filter, seals and spray arms.

How often should you use dishwasher cleaner?

Can ordinary dishwasher tablets clean the machine?

Ordinary dishwasher tablets are for cleaning dishes during a normal load. Aldi’s Magnum Triple Chamber Dishwasher Tablets are identified as dishwasher tablets rather than a separate machine-cleaning product. For an empty maintenance cycle, use a cleaner labelled for the dishwasher itself.
