Whether you use a dishwasher or wash by hand, here are some ways to improve your dish-washing to help fight climate change

You’ve probably heard that dishwashers use less energy and water than traditional hand-washing techniques.

While that’s true in most cases, a new study from the University of Michigan found one manual washing technique that is even better from the environment than using a dishwasher.

Researchers found that the two-basin method, in which dishes are soaked and scrubbed in hot water and then rinsed in cold water – is associated with fewer greenhouse gas emissions than machine dishwashing.

The common “running tap” method of manual dishwashing used more energy and more water than any other dishwashing method tested.

If by-hand dishwashers switched from the running tap to the two-basin method, they could reduce associated greenhouse gas emissions by about two-thirds.

Good news if you love your dishwasher

If you can’t imagine life without a dishwasher, the good news is the study also found ways to make doing the dishes a bit greener:

  • Don’t pre-rinse before loading dishes into the dishwasher
  • Don’t select the “heat dry” setting
  • Don’t choose the “heavy” cycle over a normal wash, except for tougher loads.
