Stop Pre-Rinse your Dishes
Every Reason to Stop Pre-Rinsing Dishes
The dishwasher does the dishes worse if you pre-rinse beforehand.
Most of us are brought up to do the dishwasher a favor, and rinse off the dirty cutlery and dishes before stuffing it in the machine, but that's completely wrong,… and actually it prevents the dishwasher from doing its duty properly.
Manual rinsing is the biggest mistake made when using the dishwasher. Large food scraps must of course be removed. But other than that, modern machines does a better job if the dishes are put in directly.
Most newer machines have rinsing programs that remove the worst dirt before the main wash starts. A rinsing program uses only a few liters of water, which contributes less to water consumption than rinsing by hand.
