Ok Folks..
I have been in contact with Brad Miller to get the 'de facto standard' by which Cleaning Media should be used.
The reuseability of Cleaning Media is highly subjective and likewise dependant upon several factors including ( but not limited to ) quantity of dirt on film, 'type' of dirt on film, film tension, film speed, film warp, 'if' cleaning solution is being used and the type of cleaning solution in use.
In a THEATRICAL environment Brad will reuse the cleaning media on the same print.
In a NON-THEATRICAL environment Brad says, "It should be changed anytime a different print is to be cleaned on those media pads, but many people have successfully used one set of pads on 2 different 'similarly dirty' prints before with perfect success"
Bear in mind that Brad is talking about 35mm films which become very dirty very quickly/easily as compared to 16mm and Super8. Likewise 35mm is used in professional venues where projectionists dont often care about their craft - versus collectors whose prints tend to be handled more carefully.
So ...
There are a number of concerns and constraints that come into play and there is no 'one' safe answer for 'how dirty is too dirty' in terms of reusing/replacing cleaning media.
Officially ? I have to take the position of " Change the Cleaning Media after one use for maximum safety, and reuse Cleaning Media at your discretion. The user must determine when the Cleaning Media requires replacement or may be rewound and reused, based upon the debris on the Cleaning Media. "
UN-Officially ? I will say you can 'probably' reuse the Cleaning Media many times - UNLESS your prints are very dirty. I have reused the cleaning media as I posted previously with great success... but my prints arent covered in sand.
The bottomline is use your common sense - if you are cleaning sand or grit off your film .. change the media since that can scratch your film. If the film is 'dusty' or has tape residue or grease .. its probably ok to reuse the media.
