Stylus cleaner

First you must have Cardas LP with frequency sweeps that ultrasonically clean the cartridge stylus and degauss the entire system.  Second is Onzow Zerodust stylus cleaner (no liquid). 

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! 

@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. 

@don_c55 i don’t know why there is nothing about cleaning (at all) in the manuals for my zyx airy and zyx 4d, but that’s why we have distributors to address our questions directly to manufacturer. I use fluid cleaning only on cheap mm cartridges, but i do not use it on hi-end mc cartridges if the distributor warning people to stay away of fluid cleaning. Rebuild of ZYX (for example) cost too much to make such mistakes.
