Contact lens cleaner for cleaning stylus cartridge ?

The only cleaner that is really safe is Lyra SPT Stylus Performance Treatment.Lens cleaner never use it unless you wish to destroy your cartridge.

In considering the OP’s question, doesn’t contact lens cleaner contain a bit of lubricant? Wouldn’t that potentially form a film on the cantilever and stylus that could pick up more contaminants?

Thanks every one for your good advice 

Has the Mr. Clean Magic Eraser been wiped from the collective Audiogon cultural memory?

Here’s a photo of a stylus that has never been touched by any stylus fluid - only the Magic Eraser:  https://galibierdesign.com/stylus-01/

@thom_mackris Thank you for that hint. I have 3 styli that are 2nd hand ("lightly used") and I have checked their condition under a microscope. apart from a lot of fibre at the neck of the cartridge the needle and rod seem to be in good shape. But as it will be a small while until I use them, I can spend some constructive time to delicately clean them, which on close inspection, the needles and rods are dull; in good shape but with vinyl build-up. The previous owners have tried to keep them clean with dunk gel pads, and the occasional brush, but not the recuperative effect of ME. Thanks again! A.
