Interesting information from Analog Planet on Stylus Cleaner Onzow Zero Dust.

I've seen a stain form on my graphite platter when exposed to a gel which looks and feels a lot like Zero-dust. So I would take @mijostyn 's caution seriously.

As for waiting until the cantilever is so bunged up with goop that you can hear it, well, you first @daveyf  . The ear just ain't that good at perceiving gradual changes.

"I am sure that is what started the investigation...."

How would you know this???

@terry9 There are many folk here who have used Zerodust for years, do you seriously think that none of them would have noticed major build up of goop by now that someone would have heard a difference in SQ???

stop using mine years ago you could hear the sound degrading 

@daveyf 

Alas, we have no idea how many of them perceived something but did nothing about it. Perhaps they had no access to a good lab, Perhaps they put it down to stylus wear.
