In short, yes, dishwashers are generally the eco-friendly choice when used correctly.

Does a dishwasher save more water than hand washing?

As highlighted in our 10 Benefits of Using a Dishwasher, modern models are designed to reduce water and energy consumption.

Does handwashing clean better than a dishwasher?

Not usually. Dishwashers:

● Maintain high water temperatures (60–70°C) for better sanitation.

● Remove more bacteria than hand washing can.

When is handwashing better?
