For a decade or two I worked in a specialty automotive/m-cycle machine shop.
When we assembled press fit rods and pistons we cleaned everything and lubed the wrist pins and put each assembly in a stout plastic bag, and explained that no other parts were clean enough for assembly. Normally balanced Pistons were returned with pins slid in bores, with pistons wrapped in groups of 2, 3 or 4, with a card advising not to interchange the pins for reasons of balance.

A shop we dealt with for cycle work returned all parts or assemblies wrapped in stout plastic bags.  There would be a pre-printed label saying the part was clean for engine assembly (assembled cylinder heads or multi-piece cranks with rods) or preserved but not clean enough for assembly (cylinders). 

Now it is almost 30 years later, and I work for a company making a MULTI megawatt superconducting motor.  The oil cooling skid is sitting a few hundred miles from here, and it has been determined that the pressure relief valve will need to be set to a new value.  The word has been spread by phone and e-mail but I intend next time I am on site to afix a brown tag with wire to the valve and to the control panel with a warning and 2 contact phone numbers.
