fastidious

He had at first tried to clean up as they ate, his fastidious nature kicking in, but Chris had told him to just stop, he was blocking the TV.

If you are fastidious, clean previously used pots inside and out; if not, merely clean the outside (unless you are battling a pest infestation; then the inside will need scrubbing as well).

You're too fastidious, and too indolent, and too rich.
