No arguments that maintaining cleanliness is critical, but I have found as I stated in the paper that even new records benefit from initial cleaning, the pressing plants are not clean. Maintaining cleanliness is addressed in Section VI, what other items should have been addressed? One of the problems is that some 'practices' are doing more harm than good. I now no longer use any brushes, just a quick visual+UV, and if necessary a swipe with the microfiber anti-static cloth to dust away lint/particulate, and my records now play better - but that is my experience.
