When we moved in together, 25 or so years ago, we had certain agreements. #1 was that the cook doesn't wash dishes. When we started out, we pretty much shared cooking duties. Over the years, hubby has more or less taken up washing (an me cooking), and he doesn't seem to mind any equipment I use. I agree -- graters are right up there. Especially when it is cheese, toss it in hot water asap, and hubby appreciates that I do that. I tend to wash my mandolin myself simply because it really needs to be washed immediately or it is a finger-threatening-disaster. But Hubby doesn't seem to mind anything I toss his way. We don't own a dishwasher, so big parties we do share the duties (both cooking and washing up). I have very unsteady hands, so I put the crystal on the sideboard until the next day, then when hubby wakes up I make up a sink of clean hot soapy water and let him do the honors (I'd break more than it would be worth)(and we don't try to clean them after a big dinner party at night -- i.e., after all that wine has gone down the throat).
