Interesting information from Analog Planet on Stylus Cleaner Onzow Zero Dust.

Do you have to use a nanoscissors to cut nanotape?

Insofar as a deposit has mass, it cannot help but affect SQ, I would think, by adding mass to the moving mass of the stylus/cantilever.  It is unlikely to have no effect. The deposit can also affect how the stylus tip sits in the groove or alter the normal stylus contact patches.  Not good either.

An "oligomer" is nothing more than a short "polymer". So, all oligomers are polymers but not all polymers are oligomers. Further, the distinction is vague; the number of units or "mers" that define an oligomer is not specified by the term. One dictionary definition says an oligomer contains from 2 to 100 units, for example. So, to say that a molecule is not a polymer but is an oligomer, does not say much, and it’s technically incorrect. It just means the chains are shorter than long.

I am still wondering about Peter Ledermann’s beef with Magic Eraser. Maybe because of this controversy about Onzow, I just examined a few of my cartridges that have been regularly exposed to ME under my Olympus laboratory microscope, and I see absolutely no problems. Further, the areas of the cantilever that do come in contact with ME are much cleaner than the top side of the cantilever (between the cantilever and the cartridge body), where the ME cannot reach.

In the old days, I used to clean styli with Stylast.  I never had a problem, but I did not own the Olympus Microscope or even think about close examination of the styli back then. I do think it's prudent to avoid liquid cleaners.

Mulv, I certainly hope you don’t “scrub” with magic eraser. I use it too, but down on the ME and up off the ME, preferably maintaining a 90 degree orientation of stylus tip to pad seems the only safe method.
