I clean up as I go along as well. There is time between cooking things to do that. I can not stand the clutter and the excess mess if not cleaning while preparing a meal.
I have noticed my wife does not do that either.
If you aren't going to clean a pan or a dish, leave it on the counter. Nothing worse than having to pull crap out of the sink so that you can get them properly put in the dishwasher.
I do, I hate the mess, now my wife on the other hand, no matter what she cooks, when she is done it looks like a bomb exploded and takes forever to clean up..........ughhh.........
