Stylus cleaner

Fluid stylus tip cleaning is strictly prohibited for most of the hi-end cartridges such as ZYX etc!

Onzow is the best solution, you will find it for reasonable price from japanese sellers on ebay.

Cardas LP with ultrasonic cleaning signal works also like demagnetizer but can not harm your MC/MM/MI cartridge.  The best tool ever! 

@ chakster

ZYX makes no mention of "strickly prohibiting" cleaning their stylus tips with a liquid cleaner on their website!

The Ozono does not clean "above the diamond on the cantiliver", and also needs the use of a brush.

Mmmmm...the Vinyl Passion is beginning to sound more appealing then...!

As many have noted the key to a good cleaning regime is actually not letting the stylus get dirty in the first place so

1. Clean LPs
2. Inspect and clean tip at least once each session (Oznow Zerodust or magic eraser)
3. Keep dust and dirt away from cantilever (i.e. keep the room clean)
4. Infrequently more thorough clean with brush/liquid or ultrasonic

As it's step #4 that is most likely to damage things it's the one to avoid as much as possible and if you are doing #1-3 regularly you should not need to go to step #4 very often at all

@don_c55  google it, i tend to trust Nakatsuka-San and Zyx distributors:

Be careful with stylus cleaning fluid. Too much over time and you can dissolve the bond between the stylus tip and the cantilever. Zyx actually warns against using fluid for that reason. I've used a Zero Dust for years now. 

Many Cartridge Manufacturers today do usually discourage the use of Liquids, and the Distributor of ZYX told me either Onzow Zerodust, or Mister Clean ME Eraser only. The fluids needed many times to remove baked on Stylus Crud can no doubt be also agressive enough to harm Stylus Bonding Adhesives.
