Washing Wednesday’s

This Washing Wednesday I found some wonderful tips about Washing Dishes and Dish Washers. Please enjoy them. I posted the link where I found them at the bottom, in-case you want to find more tips. For me, the whole reason I had kids was so that they could wash the dishes…ha-ha-ha-ha!

Dishwashing Vs. Hand-Washing

Which method uses less energy? Well, it depends on how old your dishwasher is, what settings you use, and how you would wash the dishes by hand. Studies are showing more and more that, when used to maximize energy-saving features, modern dishwashers can outperform all but the most frugal hand washer.
If you currently wash dishes by hand and fill sinks or plastic tubs with water, it’s pretty easy to figure out whether you would use less water with a dishwasher. Simple measure how much water it takes to fill the wash and rinse containers. If you wash dishes by hand two or three times a day, you might be surprised to find out how much water you’re currently using. Newer dishwashers use only 3 to 10 gallons per cycle.

Scrape, Don’t Rinse

Studies show that most people pre-rinse dishes before loading them into the dishwasher. Modern dishwashers—certainly those purchased within the last 5 to 10 years—do a superb job of cleaning even heavily soiled dishes. Don’t be tempted to pre-rinse dishes before loading; simply scrape off any food and empty liquids and let the dishwasher do the rest. This will save you time as well as water and energy. If you find you must rinse dishes first, get in the habit of using cold water.

When Filling the Dishwasher

Load dishes according to manufacturer’s instructions. Completely fill the racks to optimize water and energy use, but allow proper water circulation for adequate cleaning.

Wash only full loads.

The dishwasher uses the same amount of water whether it’s half-full or completely full. Putting dishes in the dishwasher throughout the day and running it once in the evening will use less water and energy than washing dishes by hand throughout the day. If you find that it takes a day or two to get a full load, use the rinse and hold feature common on most newer models. This will prevent build up of dried-on food while saving time and water compared to pre-rinsing each item. The rinse feature typically uses only 1 to 2 gallons of water.

Use Energy-Saving Options

Pay attention to the cycle options on your dishwasher and select the cycle that requires the least amount of energy for the job. Use the no-heat air-dry feature on your dishwasher if it has one. If you have an older dishwasher that doesn’t include this feature, you can turn off the dishwasher after the final rinse cycle is completed and open the door to allow drying. Using the no-heat dry feature or opening and air-drying dishes will increase the drying time, and it could lead to increased spotting, according to some in the industry. But try this method some time to see how well it works for your machine.

Turn Down the Water Heater Temperature

Since the early 1990s, most dishwashers in the U.S. have been sold with built-in heaters to boost water temperature to 140-145 degrees Fahrenheit, the temperature recommended by manufacturers for optimum dishwashing performance. The advantage to the booster heater is that you can turn down your water heater thermostat, significantly reducing water-heating costs. Resetting your water heater to 120 degrees Fahrenheit (typically halfway between the “medium” and “low” settings) will provide adequate hot water for your household needs.

    Fabulous tips … thanks so much! I really like the last tip about not needing hot water to run a dishwasher. It’s really redundant (and a waste of energy) to keep our water heaters at a high temperature when the dishwasher, itself, has a heating coil. Another thing is that most dish detergents are designed to clean and kill germs in cold water so, contrary to what we’ve always believed, we don’t need hot water to do the job.
