Stylus cleaning does indeed require care, attention and calm, steady fingers. Good eyesight helps too.
There are risks, but you should also be afraid of NOT cleaning your stylus, particularly a ZYX stylus.
A major part of a ZYX's performance is due to its fine contact ridges, the finest used by any cartridge manufacturer. These gunk up VERY easily, at which point your cartridge will stop sounding like a $3K LOMC and start sounding like a $100 MM. I guarantee this will happen if you use inadequate cleaning solutions, poor vacuuming or fail to clean the stylus after EVERY SIDE.
As the founder of the Magic Eraser as stylus cleaner, I've been using it on ZYX UNIverses, Atmos's and other cartridges for 6+ years. No accidents so far and my styli are as clean as the day they left the factory. That will not be true if you use a ZeroDust (and definitely not if you use a ZeroStat!) ;-)
P.S. You aren't getting many responses because this has all been covered before. Do a search. Your Mint question would be answered with one glance at their website. No offense, but do a little homework. That can be fun too. :-)
