Flux HiFI Electronic Stylus Cleaner

.. 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.
