Nobody agrees on what "clean code" is. I agree there are rules of thumb most will accept, such as try to be modular (group related things together), manage constants in a table or central class instead of hard-wire them, factor heavily repeated patterns into subroutines/methods/classes, comment at least the "big picture" of sections, and the oddities.
