Dishpan hands go green

You've cooked up a tasty meal of fresh, local ingredients. Maybe you even relaxed with a glass of organic wine. Now it's time to clean up after dinner.

What if your charmingly retro house or tiny apartment doesn't include an automatic dishwasher? Can hand-washing the dirty pots and pans still be earth-friendly? Sure, but it takes a little elbow grease.

An oft-quoted study from the University of Bonn, Germany, found that people who hand-washed dishes used 27 gallons of water and 2.5 kWh of water-heating energy on average to clean 12 place settings.

This was dramatically less efficient than the dishwashing machines tested -- they used about 4 gallons of water and 1 to 2 kWh of energy.

But if you just can't afford an Energy-Star machine right now (or, like me, your 1940s kitchen is too narrow for one to fit into!), you can still learn to wash dishes better.

First, install an aerator on your faucet. These inexpensive little devices turn a wasteful sink into a low-flow water saver, and you won't really notice any lack of drippage. Put one in the bathroom sink too, while you're at it. It'll cost you maybe $3 per faucet.

Next, scrape your dishes after eating, instead of rinsing. You shouldn't need to soak them unless food has burned on. And try not to let food sit and dry on dishes, if possible.

When it's time to wash a load, do it efficiently by using dishpans or getting a plug for your sink. If you wash dishes with the faucet running, you might as well pour money down the drain. Your water bill goes up, valuable resources are lost, both you and the planet suffer. Who wants that?

Wash the dishes in a pan of hot water and rinse in a pan of cool water. Or if you have a double sink, use plugs and fill up the sinks.

One eco-bonus that hand-washing has over the machine is that many of the detergents for automatic dishwashers still contain phosphates. Dishwasher detergents are one of the last types of cleaning products in the U.S. still allowed to include this harmful agent. Liquid detergents used for hand-washing dishes are usually phosphate-free, so they don't gunk up our waterways.
