We skip the sink and put our dirty dishes right into the dishwasher throughout the day, and start the cycle as we're locking up the house to go to bed...and empty it again first thing in the morning while making breakfast. I scrap the big chunks off and give the plates a quick rinse if there is a lot of gunk, but that's probably not necessary since we have a very new/heavy duty DW. Hand-washed things are usually washed right after use; wooden cutting boards, the good knives, wine glasses, cast iron, that sort of thing. Everything else goes in the DW, and on the top rack if I'm nervous about that. To save energy, I always turn off the 'heat dry' feature since the things have several hours to dry overnight.
