A Guide to Efficient Dishwashing

Read Time:3 Minute, 32 Second

Built-in dishwashers were once widely regarded as more energy-efficient than washing dishes by hand, but recent research could cast doubt on that assumption. Now there are reports which may cause dishwasher advocates to reconsider.

A recent study has discovered that handwashing using the two-basin method (using one sink to dilute soap and water, followed by another one to rinse) produced significantly lower greenhouse gas emissions than any other form of hand washing studied.

1. Water

Dishwashers utilize significantly less water than hand-washing dishes by hand. To be most energy efficient, opt for models bearing the ENERGY STAR label – they use up to 13% less energy while simultaneously consuming 30% less water than standard models.

By hand, washing dishes uses more water than you may realize, particularly if you rinse your dishes before loading them into your dishwasher. In fact, it takes around two gallons to cleanse a single sink full of dirty dishes before even turning on your machine!

Additionally, dishwashers heat their water to higher temperatures than what comes out of the faucet, helping sanitize dishes more thoroughly than cold water alone. Unfortunately, however, these higher temps can burn your hands and dry out skin – if you plan on washing dishes by hand be sure to invest in quality gloves, and rinsing delicate or wood kitchenware pieces in a tub of hot water before placing on a drying rack for best results.

2. Energy

Assuming that washing dishes by hand consumes more energy than using a dishwasher might seem bizarre, it is true. Dishwashers reach temperatures between 140 and 145 degrees Fahrenheit which exceed what human hands can tolerate and effectively kill bacteria while simultaneously providing better sanitization than hand-washing using soap and water can.

But according to a recent study, the most energy-efficient way to clean dishes was with two basins in a sink: fill one basin with hot water while using another as the secondary basin for soaking, scrubbing and rinsing purposes – using half the greenhouse gases produced from traditional handwashing! This technique used less than half the energy.

No matter if you use a dishwasher or hand wash your dishes, be sure to run full loads. Running the same amount of energy for an empty or partial load makes no sense at all.

3. Space

A dishwasher can be an indispensable kitchen tool, freeing up valuable counter space for other tasks and providing valuable assistance for large families, households that regularly host guests or individuals with physical limitations who find it challenging to wash dishes by hand. It can also make life simpler for individuals living alone who might find doing dishes by hand a difficult task.

High temperatures used by dishwashers help sanitize dishes by eliminating germs and bacteria that might accumulate, contributing to healthy cooking by providing surfaces on which meals can be prepared more safely. This promotes healthier living.

A dishwasher may also provide an ideal solution for those struggling to wash dishes by hand due to arthritis or other health-related issues, providing gentler treatment to dishes than hand-scrubbing them by combining hot water and detergent, protecting them from damage. Furthermore, many modern models feature energy and water efficiency features to reduce household utility bills.

4. Time

Dishwashing by hand can be both time consuming and tiring, particularly with large loads of dirty utensils to wash. Furthermore, this method can be detrimental to your hands; to make things easier when hand washing dishes use dish gloves or limit how long your hands remain immersed in hot water; otherwise friction caused by this method could result in dry skin or chapped fingers.

Handwashing dishes is also a breeding ground for bacteria, while using a dishwasher reaches temperatures between 140-145 degrees Fahrenheit to kill off any germs on your dishes and leave them sanitized.

If energy usage is an issue for you, energy-efficient appliances are available. Check your local utility company’s website to learn about peak and off-peak hours so you can save energy during more costly hours. Furthermore, purchasing dishwashers certified by the Environmental Protection Agency to reduce carbon footprint may help; such models utilize less water and electricity during rinse and drying cycles than similar models do.
