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

For what it's worth, even though I will absolutely hate going back to using a stylus brush, with or without cleaning fluid, distilled water, purified water, alien Elixer or whatever, I'm now doing some research on liquid stylus cleaners. I asked Music Direct what "both a stylus cleaner and a stylus preservative" meant with regard to Mobile Fidelity's LP#9 liquid cleaner. They responded by saying this solution does not leave behind any kind of coating on the stylus. So, apparently, the mention of "preservative" alludes to the fact that a clean stylus will last longer. LAST Stylus Cleaner basically advertises the same effect but, unlike LP#9, they say their solution does not contain alcohol. They also say their solution removes the most stubborn crud. Mobile Fidelity and The Last Factory are two authoritative sources I have the utmost respect for. I was going to add Michael Fremer to that list, too, because of his support for Audio Intelligent Stylus Cleaner. However, after this latest half *** stunt of his in Analog Planet, he's gone down a couple notches in my pantheon of trusted sources, if you know what I mean.

@rickd1225, God Bless You for your expertise on this!

I have no idea what all the technical polymer chemistry stuff means but, like you, I've been using the Onzow Zerodust stylus cleaner for a while, now, with no unsavory effects I can discern. No problems with sound quality and nothing of any concern I can see on the stylus. However, the magnification I've been using to observe the stylus is pretty pedestrian. I also agree that Mr. Fremer, WAM Engineering/Wally Tools and J.R. Boisclair have gone off half-cocked on this. Strictly based upon what has been reported, thus far, however, I have to say, regrettably, that the brunt of responsibility, here, rest squarely on Mr. Fremer's shoulders.  WAM/Wally Tools/J.R. Boisclair are simply reporting on what they're seeing, thus far, and what the styli owners have, it would seem, reported to them, regarding these styli deposits. It wouldn't surprise me, at all, if Onzow Labo, DS Audio and maybe some other manufacturers of some of these gel-type cleaners consider litigation if their sales are negatively affected by this half *** reporting. It would behoove Mr. Fremer to do everything within his power to get to the bottom of what these deposits really are and where they are really coming from and do it FAST!

Update: Here's a little ditty I found interesting on this subject on Youtube:

Is The Onzow Zerodust RUINING Your Stylus? - YouTube

Yes! This is certainly disconcerting news for those of us vinyl heads who never liked free-handing stylus brushes. Every time I did that, I channeled a special ops sniper holding his breathe before squeezing off a round! The Onzow and some of the other goop stylus cleaners, handled appropriately (i.e. not free-handing, as some instructions advise, but locating a safe, non-movable spot at the correct height so as to allow just the tip of the stylus to contact the goop; not the cantilever and using the TT cueing device to lower & raise the stylus into & out of the goop), seemed like the perfect solution! DAMN! Now, it's back to channeling the special ops sniper?

Some have criticized Mr. Fremer and WAM Engineering for this sort of half-baked alarm. However, half-baked notwithstanding, I would rather know about stuff like this before continuing to use my Onzow. The first article stated: "An analysis of the residue shows it is not silicone but rather a polymer of some sort." Then, in the follow-up article Wally Tools said: "I got more news from the lab yesterday (it is coming in slowly) and the material is an oligomer, not a polymer, so it can't be polyvinyl chloride." I'm not a chemist. So, I Googled "oligomer". Some sites say it is a polymer. Some say it's a polymer intermediate. Well, is or are the residual deposit(s) still "not silicone"? Isn't the Onzow and some of the other goop cleaners silicone or silicone-based? If it's "not silicone" would it be reasonable to conclude these residues are not coming from the Onzow and silicone-based goop cleaners? Is it possible use of these goop cleaners cause, in some or any way, the build up of these deposits? Seems, to me, we need to know where this or these deposits are coming from and exactly what they are. At this point, we are all chasing our tails. It also would be instructive to know if this or these residual deposits are all the same from one stylus to the other. There are simply not enough controls, thus far, to come to any hard & fast conclusions. It would be great to hear from Onzow, DS Audio and the others.

Just thought I'd post this as a follow-up, for what it's worth. I got tired of waiting for people like Michael Fremer, WAM Engineering and J.R. Boisclair to do the obviously right thing under the circumstances (i.e. ask the manufacturers or makers of Onzow Zerodust and other gel stylus cleaners for their feedback or response). So, I took a stab at it. I was hoping for more detail. However, I'm just some guy, some audiophile out there in the great ether asking general questions about their product. I would assume someone with considerably greater stature in audiophile circles would get a more substantive or in depth response. I would think Michael Fremer, at least, owed that to his readers & followers. I hope Onzow Labo takes the time to read the articles published in Analog Planet and respond directly. Anyway, here's the response I got from Mr. Akira Ishibashi of Onzow Labo of Yokohama, Japan:

"Thank you for your inquiry:

We carefully select resins that do not build-up residue from the beginning of develop ZERODUST. No residue build-up to the stylus. The materials are completely different from the products of other companies. ZERODUST has no adverse effect on vinyl records too. This is because ZERODUST is made of material with the same properties as mold release agent used when pressing records. Please use it with confidence.

Sincerely,

Akira Ishibashi

Onzow Labo"

I must confess I'm more than a little disappointed we haven't seen or heard much in the way of substantive follow-up, lately, on this question from Mr. Fremer, WAM Engineering, Wally Tools, Onzow, DS Audio or whomever. Seems all the audiophile gods have been silent for a while, now.

I contacted Mobile Fidelity a few days ago to see what they might recommend with regard to stylus cleaning and, also, to see if they had any thoughts about the Onzow Zerodust or gel cleaners, in general. They've never failed to respond, yet. When (or if) I get a response, I'll share. In the meantime, here is my experience with regard to using the Onzow:

I haven't been using the Onzow for very long. Only records I've ultrasonically cleaned, first (even new ones), have been played on my relatively new TT & cartridge. I use the Onzow before and after every side. All my records are in anti-static poly sleeves and have been very well cared for and stored since I bought them. All the records I've played have been treated with LAST record preservative. I use an AudioQuest carbon fiber anti-static brush before & after every play. For what it's worth, I also use a Michell record clamp. One change I'm going to make, now, is to use the AQ brush BEFORE I use the Onzow and immediately after, right before play, instead of using the Onzow, first, and brush, second, right before play. Probably obsessive overkill but what the heck! Doesn't really take that much time.

When I use the Onzow, I do not free-hand it (i.e. raise it to the stylus by hand). I set in on a little block, on the plinth, at the proper height, so I can use the TT's cueing lever to lower the stylus onto and off of the Onzow's gel pad. I do this 2 or 3 times, moving the block & Onzow around just a little each time to give the stylus a clean landing spot each time. When I first started using the Onzow, I didn't notice any deposits on the gel pad at all and wondered if my records and stylus were really that clean. However, lately, I've noticed ever so tiny little black spots or specks, here & there, on the Onzow gel pad. I'm assuming this means the Onzow is doing what it's supposed to do. Is it getting everything? I've used the magnifying cover of the Onzow box and, also, a very small hand-held stylus microscope I have to examine the stylus. However, both of these are extremely limited and don't really give as good a view of the stylus as I'd like. I just might invest in a jeweler's loop or something better. From what little I have been able to see, the stylus looks relatively clean. I can't really say with any degree of certainty what the black spots on the Onzow gel pad really are. My assumption has always been that it's probably whatever dust & crap the Onzow picks up from whatever the stylus picks up in the grooves. My non-scientist's assumption has always been that these tiny black specks are probably PVC shavings from the records, dust and whatever other crap hides in those grooves. LAST treatment or not, considering you've got a highly polished diamond doing a complicated dance in those tiny little PVC grooves, the friction and heat going on in there has to be wearing away some amount of PVC. Anyway, that's what my non-scientist's mind without an electron microscope has always thought.

As for continuing to use my Onzow or going to a liquid cleaner, dry stylus brush, stylus brush with distilled water, ultrasonic stylus cleaner, combination thereof, etc, etc, etc,, I haven't decided, yet. There are SO MANY opinions on this! It would be nice to see a showdown review or several showdown reviews on this with a healthy amount of scientific acumen applied, including, of course, electron microscope shots. However, I doubt this will ever happen. Something like that would put some people & products out of business. Then again, there are some minds impervious to science who would just go on using whatever they firmly believe in, anyway. So, I don't see the harm. Might even be a good marketing investment.

I've used a stylus brush and liquid cleaner in the past and would really, really hate to go back to that! Music Direct has said, in the past, that they use the Onzow and, occasionally, Mofi LP#9 for stylus cleaning. Don't know if they are still using that approach. I'm not sure if Mofi LP#9 is a non-solvent cleaner, per se. Fremer says he subscribes to the use of non-solvent cleaners and uses Audio Intelligent stylus cleaner, an enzymatic formula. Aren't enzymes just another solvent? If memory serves correctly, I believe LAST stylus cleaner is also a non-solvent formulation. I'm sure there are probably other non-solvent type liquid stylus cleaners and all sorts of other concoctions out there, as well. As for the Onzow gel breaking down over time, I can't remember where I read this; might have been reviews, but I do recall reading that this gel is supposed to last a very, very long time; virtually forever, even after cleaning (by running warmed distilled water over it). Nothing lasts forever! And then, of course, there's Magic Eraser, BlueTack, etc., etc.

What's a poor confused vinyl head audiophile to do?

In the end, I suspect we may very well learn that many, if not all, of the different reputable stylus cleaning approaches are effective; just different. Either that, or we will all be left to our own devices and this will prove to do be much ado about nothing, like many things in audiophilia nervosa.

Here's some news or, rather, pseudo-news from someone who claims to be the New Zealand DS Audio Distributor, on behalf of someone named Aki who is... the creator of the DS Audio gel stylus cleaner? Not terribly clear! This was posted recently as a comment under the follow-up article in Analog Planet:

"Hi Stephen here from Soul to Sole Audio.... I am the New Zealand DS Audio Distributor and Aki has been made aware of the comments, regarding his ST-50 Stylus Cleaning Pads, that have been dragged into this conversation about Zerodust.

Here is the info he has posted:

"DS Audio designed and manufactures our ST-50 stylus cleaner for numerous good reasons. Before developing the ST-50, many people used a liquid-type cleaning brush with resulting problems such as compromising stylus adhesive and oxidation of metal parts. There were instances of customers damaging the stylus/cantilever using a small brush for the cleaning or impacting the cartridge suspension by brushing incorrectly.
This is why we developed the ST-50 pad-type stylus cleaner. It is mechanically safer and there is no chemical fluid that may damage the cartridge. The shape of the pad and its low profile allows you to cue down the stylus gently on the pad with no cantilever contact.

We specifically chose a lab grade of urethane gel that is ether based. The two basic formulations of urethane, ester and ether, have some important differences. Water attacks ester-based urethane, causing a significant reduction in physical properties. Ether urethanes exhibit far superior hydrolytic stability (water not reacting with another chemical), especially in humid environments. Ether-based materials also resist fungus growth better than ester-based materials."

Don't know how you folks feel about this comment but, to me, as a non-chemist consumer audiophile, this is nothing but obfuscation. This comment is like that scene in "Peanuts" where Lucy pulls away the football right as Charlie Brown is about to kick it. Misses the point entirely! Stating that the DS Audio gel cleaner is "mechanically safer" is reassuring but I think most of us who bought a gel type stylus cleaner figured that out before we bought one. Indeed, I think that's why most of us bought one in the first place! We still need or would like to know what the deposit or deposits on the styli are. No news from the Wally Tools Lab on this in a week and nothing of any substance on this from Mr. Fremer in longer than that. If Mr. Fremer isn't closely following up with Wally Tools Lab/WAM Engineering's J.R. Boisclair on this, I will consider this extremely irresponsible! If these folks end up leaving us all swinging in the wind on this one, it will be tantamount to starting a fight in a bar and, then, cowardly slinking out the back door!

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)".
