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

@oldaudiophile thank you for your follow up.

Still have my reservations. And I am going to pull a stylus and take it to our lab in Ohio to see if we see any residue. 

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.

This is a recommended cleaning practice from U Turn.

Thank you for the follow-up with Onzow's response!

I'm in no position to make a scientific assessment or educated guess, so here's my uneducated guesses:

The stylus gunk show in the infamous pics is simply mold release agents and other crap from vinyl records, accumulated over time. The Onzow and DS Audio gel dips are NOT abrasive enough to fully prevent this buildup, over time. They DON'T contribute to the gunk; they're the wrong bogeyman. They simply aren't powerful enough to clean it off. Regular dry brushing, and ME dips may or may not be enough to prevent gunk accumulation. Occasional regular liquid cleaner use, the ME "scrub" methods, and/or ultrasonic cleaners are almost certainly strong enough to prevent gunk buildup when used properly & regularly. 

All of the pics show a filthy, disgusting cantilever that is the telltale sign of an inadequate cleaning regimen. Whatever cleaning regimen you choose, full stylus & cantilever brushing should be a part of it. 

@mulveling .. +1 on this:

"Whatever cleaning regimen you choose, full stylus & cantilever brushing should be a part of it."

Sometime over the last week my vinyl lost some of the magic. As part of this Onzow gunk thread, I've been scrutinizing my cartridge with 8X magnification. From both sides, from the front, from the back. Seems a small hair or fiber wrapped itself around the cantilever and was acting as a leash on the motion. Very carefully unwrapped it since just a back to front brushing wouldn't dislodge it. Adding regular magnified cartridge inspection to my routine.
