Get clean dishes from your dishwasher

Dishwasher Usage | Pre-Rinsing Dishes

Should I rinse my dishes before placing them in the dishwasher?


Here is what a local “authority” recently wrote in an article in the Arizona Republic regarding pre-rinsing dishes. “Before loading the machine, rinse dishes thoroughly to remove both large and small food particles.” WRONG.

FACT: “Experts unanimously agree that you should NOT pre-rinse your dishes before loading your dishwasher.”

Here's why:

  1. You're wasting time and energy. Today's dishwashers are very energy efficient. It's likely that if you spend time running water to get it hot, and then rinsing your dishes before placing them in the dishwasher that you will use MORE energy pre-rinsing than in the entire dishwashing cycle. Rather than wasting time and energy pre-rinsing your dishes, spend a little extra time in the loading process to make sure that your dishes are carefully loaded. A senior design engineer for one of the leading dishwasher manufacturers says, “The biggest impediment to washing is due to poor loading.”
  2. Your dishes won't get cleaner. Standard dishwasher washability tests from both AHAM (Association of Home Appliance Manufacturers) and Consumers Union are done with soiled dishes. Obviously, scraping off chicken bones and large chunks of leftover food makes sense. Pre-rinsing does not, as dishwashers are proven to get dishes clean without pre-rinsing.
  3. Pre-rinsing dishes not only does not help get them clean, it can actually make matters worse. The active cleaning agent in dishwashers holds dirt particles in suspension in the water so that they can be flushed away when the dirty water is drained from the dishwasher. Absent any dirt, the detergent itself can wind up adhering to and leaving a film on the dishes. Worse yet, lacking soil to attach itself to, gritty detergent molecules can cause “etching” on glassware resulting in blueish cloudy appearance that permanently damages the glasses.
