As an aside I have been rolling through a few cartridges on my FR64S lately, primarily to see whats worth keeping, and one learning was that it is so much easier to clean cartridges when you can take the headshell off. Honestly I dont think it is possible to properly clean a cartridge without removing it.I hear ya brother......
And you're not wrong 👍
Not only is it difficult to properly clean a cartridge whilst it's mounted in a tonearm....
It's impossible to INSPECT the condition of the stylus.
It's one thing to CLEAN your stylus....it's quite another to ENSURE the stylus has been properly cleaned 🧐
To do this....a minimum 60x LUPE is required.
With it's own LED LIGHTS you can see whether the 'crud' has been fully removed and whether the diamond is shiny.
Note: It won't be able to show whether the stylus is 'worn'. A professional microscope and experience is needed for that.
For years I have been using a soft-bristle brush to firstly wipe the stylus from front to back (as recommended) followed by a dip in MAGIC ERASER followed by a dip in ONZO ZERODUST.
It was only after the arrival of my 60xLupe that I saw the 'hairs' and 'dirt' often left on the stylus by the BRUSH 😱
This detritus was often difficult to remove even with the Magic Eraser and Zerodust so that a wet clean with Isopropyl Alcohol was the only successful remedy.
I now NEVER use a brush......
Only the Magic Eraser and Zerodust followed by the 60x Lupe inspection.
And this is done after EVERY listening session.....🤗
