If you want to get the most out of your dishwasher, don’t rinse the dishes before you put them in the appliance.
Pre-washing not only takes time and wastes water, it also prevents you from enjoying the performance of your appliance. And for good reason: by rinsing the dishes, you assume that there will be no more stains on the crockery.
However, dishwashers operate at high temperatures to ensure that the dishes are perfectly clean at the end of the wash cycle.
The hot water with detergent is responsible for the cleanliness of your dishes, not the pre-rinse.
If you get into this habit, you are limiting the potential of the dishwasher, but you are also wasting a valuable resource: water. Simply scrape the dishes without rinsing them and then put them in the dishwasher to rinse.
