It's just that the pen light test does show everything. That is its value. It is up to the person making the test not to over-react to every mote and bit of fluff. However, an outright cloudy appearance does indicate the need for disassembly cleaning.

That being said, I always look through a lens I'm considering with a penlight. Carl Socolow
