Location codes are the reason nothing moves
In a small-parts store the value is not in any single item but in knowing where each item is. Bins are labelled to a shelf, a bay and a level, and a system somewhere holds that map. Shifting a bin two positions to the left costs nothing in a physical sense and costs a great deal the next time somebody picks against the record and finds the wrong part in their hand.
That makes the cleaning instruction unusually simple. Nothing on a shelf is lifted, slid or turned. Dust on frames and shelf faces is removed around what sits there. If a bin has been left on the floor or on a gangway, it is reported to the storeman rather than returned to a guessed position, since a wrong guess is worse than an obvious misplacement somebody can see.
