Drought washing.

Once again another useful tip from Organic Housekeeping:

Wash your dishes as if you were in a drought. Remove all dishes from your sink. Start off with utensils, place them in the sink and add dish detergent to your dish rag. Wet it with hot water and proceed to wash all the utensils with just the rag. Put the utensils in a rack to "marinate" as you wash more. Once you are finished turn on the hot water and rinse off the soap and let the utensils dry.

Then do the same for the plates. Soap them up, set them aside, and once all done wash them off.

Last but not least, your greasy pans. Repeat the process and you're done.

This way you save water.
