Flux HiFI Electronic Stylus Cleaner

I think the Flux is the same as the Hudson, and while it vibrates, it certainly doesn't do so at U/S frequencies (>20kHz)d  

Having gone through this, I did look at the Hudson Hi-Fi Cleaner, especially as it sells for around $35 as opposed to the $149 retail for the Flux Hifi ..

The Hudson version vibrates at around 222hz according to one of the answered questions on the Amazon site.  ( The Flux Hifi vibrates at a similar hz, if I recall correctly ) These lower vibration frequencies seem safer to me on a delicate stylus, though I’m only guessing here. 

Although it’s hard to tell from pictures on Amazon, the bristles on the Hudson seem different to those on the Flux, and may be possibly coarser, than the ones I’ve personally examined on the Flux.

The Flux Hifi was added to Amazon in May of 2018,  and is made in Germany, while the Hudson version was added to Amazon in February of 2021, and is made in China.

So to say that the Hudson is a much cheaper Chinese knock-off may not be entirely inaccurate.

So there’s that .. 

.. and just to add, I did check the cleaning results on a digital microscope I bought for the express purpose of examining my stylus. Clean as whistle. 👍

Don't forget to consider the amplitude of the cleaner's vibrations. My Hudson, be it vibrating at my estimated 100Hz or your reported 222Hz, has vibrations that wiggle the stylus and cantilever considerably. Way more than a record groove could.

The S-Duo makes such fine amplitude vibrations that the cantilever does not move perceptibly. Now what I do not know is how the epoxy or whatever holds the stylus on to the cantilever will cope with either kind of cleaning vibration. I would guess, and it is a guess, that tiny amplitude vibrations at 40kHz are less likely to destroy the glue than large amplitude low frequency—222Hz—vibrations. I suspect more force and larger movements are more damaging than small forces, and small movements at higher frequencies. That's why I'm experimenting with older cartridges and seeing what happens.

I do have a couple of USB microscopes, but I don't know where they are after a recent move. So, if Amazon and the seller do their thing correctly, I have a rather expensive USB microscope and stand (an updated version of Fremer's recommended device for SRA adjustment) on the way. It may be I shall be able to take some comparative pictures.

I've been using the Flux Hifi stylus cleaner for about 3 years.  It's the best stylus cleaner I've come across to date.
