WHY We can each waste about 6,000 gallons of clean water a year by pre-rinsing dishes. We will save that clean water by scraping off dishes instead of rinsing.
HOW Before dishwashing by hand or machine*, scrape off leftovers with a fork or rag. (Rinse just the rag to use again.) A little food left on your plate can actually be good. *If your machine is newer, you probably don't need to wipe or rinse.
