In cleaning my refrigerator, I realized I overlooked another place where clutter can build up: on TOP of the fridge itself.
If your refrigerator has cabinets or something directly above that prevents you from using it as a shelf, then you don't have this problem. Though maybe you want to consider dusting the top once in a while. Otherwise, I've seen the top of the fridge become a magnet for clutter. I guess the reason for this is pretty simple: it's easy to put stuff on there because it's a flat surface in a common area, but it's not something you often look up and notice often enough to sort through it.
In my own case, I found at least 3 bags of long-since-expired chips of some variety. I was happy to toss them. And from now on I'm going to try to keep this area in mind. I'd insert some poetic comment here about "not seeing the forest for the trees" and trying to relate that two in interior and exterior of the refrigerator...but I can't think of anything clever.
(On a side note, why does "fridge" have a 'd', but "refrigerator" doesn't? I checked several spell checkers and dictionaries on this, and that's how it is. Other people don't understand it either.)
