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

My biggest questions to MF, which have NOT been answered, is regardless of whether the Onzow leaves a deposit on the stylus ( which IMO has NOT been absolutely proven yet) is a) is the stylus deposit in any way detrimental to the stylus life, and b) does it impact the SQ? These may be difficult questions to answer, but I would think that if the answer was yes to either question, that would have been determined years ago by the numerous users of the Onzow.

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.

Yeah, I was thinking maybe it could affect SQ via added tip mass. And since rigidity is key in this part of the assembly to accurately transmit vibrations, any compliant/damping goop on there could slightly "muddy" the transmission. But beyond that, the pics mostly seem to show the accumulated goop on the stylus shank, not the actual contact lines of the tip (the cantilever crap looks more like a total failure to clean up there). Maybe the tip is actually "clean enough" as far as groove contact goes? But the question on stylus life is a good one.

Either way, a good cleaning regimen would keep all bits - tip, shank, and cantilever shiny clean like new, which must result in the best playback performance. Don’t ONLY use the Onzow or DS Audio pads.

OK, boys & girls, here's the response I received yesterday from Mobile Fidelity Sound Lab:

"We still recommend the classic – LP#9 Stylus Cleaner with an appropriate stylus brush. While we definitely understand the anxiety that comes with having to make any contact on a nice stylus, as long as you are brushing the tip lightly from back to front a couple times there is no risk of damaging the stylus. You have to consider that the tonearm itself puts as much or more pressure on the stylus with daily use – they are definitely fragile, but as long as you are following the proper cleaning technique there is nothing to fear!

I personally don’t have much experience using any of the “gel in a tiny tin” cleaners so I can’t speak much as to their effectiveness compared to a cleaner and brush, but if you are worried about damage from using those then I firmly believe the “if it aint broke, don’t fix it” mantra applies here. Hope this clarifies, let us know if you still had any other questions!

Kind of assumed they would recommend their LP#9 which, BTW, the Music Direct website states is "both a stylus cleaner and a stylus preservative". It's not clear, to me, what "preservative" really means in this case (e.g. putting or leaving behind some sort of chemical coating on the stylus or just the inference that a clean stylus helps preserve or prolong its useful life). Can't imagine it would be the former because the Music Direct website also states it "contains a Mil Spec IPA (Isopropyl alcohol)".

I don't blame MoFi for not wanting to wade into this one. A very reserved and measured response, with a sales pitch too, lol!

He's right though, in pointing out that too many audiophiles are too skittish about applying proper brushing. And in comparing that to the (usually greater) forces it encounters during normal playback. Again, watch a stylus slam into the 1st music groove after being dropped in the outer lead groove of a spinning 12" 45 RPM.
