A deep clean combines manual maintenance with an empty hot cleaning cycle:
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.
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.
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.
Use a dedicated dishwasher cleaner during an empty hot cycle, alongside manual cleaning of the filter, seals and spray arms. Which? recommends a dishwasher cleaner rather than vinegar, lemon juice, bleach or other strong cleaners. NEFF’s Machine Care guidance pairs its programme with machine-cleaning products.
