Which detergent should I use for the dishwasher?
Gel, powder and tablets are all types of detergents that you can use for your dishwasher.
There are also so-called “all-in-one” products that contain both salt and rinse aid.
It is recommended to use them with a “tablet” programme, if your appliance has one, and to place them in the detergent drawer and not in the cutlery basket.
As you will have understood, it is recommended that you do not pre-rinse your dishes before putting them in the machine in order to optimise rinsing and make further savings.
