Koetsu Rosewood - Best/safest way to clean stylus


I have a Koetsu Rosewood Signature and have been cleaning the stylus using LAST (I think that is the brand) liquid with a brush, followed by using the cueing to drop the needle onto a Magic Eraser 4-5 times. I think this works pretty well, but I worry about the liquid... having read about liquid wicking up the cantilever, etc.

Could using liquid damage the cartridge? Could dropping the cueing down onto the Magic Eraser "grab" the needle and damage the suspension as I raise it? It seems like the only safe way to use Magic Eraser because I don't trust my hands to be steady enough to do it any other way.

Is there another cleaning method that has actually been proven (via microscope) to clean the needle safely and be safe for the cartridge?

Thanks

My experience is the same as LewM. I used a usb microscope and the ME makes the stylus spotless, unlike liquids or Onzo. Having someone else repeat that result makes me even more confident.

I guess the remaining question is the reality that ME can probably pull a bit on the stylus as the cueing is raised. as Larry mentioned. I think a possible way to reduce the risk would be to use a smaller patch of ME -- so lightweight that it could be picked up by the stylus if it got stuck. This would reduce the maximum pulling force possible on the stylus that might occur in the worst case, and would serve as a warning that the cartridge is getting stuck. I imagine the ME would release quickly once it moves a tiny bit as the stylus pulls it up. And it may never happen anyway.

I may cut a very tiny square of ME and weigh it to ensure it is a fraction of a gram or something ... Then cue the needle up and down a bunch of times to see if it picks up such a tiny patch of ME. Maybe there is an optimum weight of ME that allows the stylus to release but has little enough mass to avoid pulling too hard on the stylus.
(Who knows what "too hard" is though).

In the past I have watched to see if the cantilever is "pulled" downward as I raise the cartridge out of the ME, but have been unable to spot that movement.

Also: I asked the Koetsu distributor and he said there is no one best way that he knows of. He personally uses MoFi or Lyra SPT and worries that anything you dip the stylus into seems "too aggressive" to him, given the potential stress on the cantilever.


As I said before, while I have no evidence the "catching"/that occurs when using ME causes any negative stylus life, it doesn't seem to be a normal issue a cartridge manufacturer would account for.

I don't need to see the "catching" effect, I can feel it.
 The force between the magic eraser and the stylus and cantilever should be equal to the VTF . Unless the stylus snags the magic eraser. But I don’t think that can happen, if you don’t move either the stylus or the magic eraser in the horizontal plane while the two are in contact. And the contact can be extremely brief. One second is sufficient.Like I said, it’s really too simple for most of us.
I was worried about my stylus, thought it could just be dirty but what if its something much worse? So I went to see my doctor. Doctor told me I have a slight hearing loss in my uber-hypochondria.

Oh no wait, that was Hannah and Her Sisters. Nevermind.



Millercarbon, don't worry. Duane can take you to the airport.

Lewm: Yes there can be no more than VTF force while it's going down. It is going up we are wondering about. You would think there would be nothing to "catch", given the shape of the stylus. Unless the cantilever gets below the surface of the ME. Not sure. I feel a little like Slaw in that I do seem to sense a catch when I raise the cueing. But it may be the sound that creates that illusion for me, not something physically catching. I'm going to do the experiment with a very small square of ME and see if it catches and picks up the square, even momentarily.

Amazing and pathetic I am willing to spend time on this, but I am!
