Put a halt on pre-rinsing. You bought that dishwasher for a reason, right? So why do all the work for it, anyway? Nixing pre-rinsing saves water (all that pre-scrubbing uses up to 6,500 gallons, according to Consumer Reports), and keeps a little more green in your wallet. Simply scrape off the chunks with whatever utensil is handy and allow the dishwashers to show off. You'll be surprised at what they can do!
