How effective is the Onzow Zerodust?

Syntax, is that some kind of vibrational cleaner?

Go with Magic Eraser. It really works great. I strongly recommend adhering it to a coin(for weight and convenience)and lowering the arm into it a couple of times. Vs. the method mounted on a toothpick, it seems less likely to do any damage. Cheers,

T_Bone, yes
It is the best and absolutely safe from handling and for the needle.

Wow - thanks you guys!!! I was reading this thread, thinking about the Onzow. I thought Magic Eraser was some kind of audiophile tweak like tube dampers, until I googled it. Obviously, I don't do the cleaning in my house! A $2.79 household cleaning product that makes my stylus sparkle? Holy clean-stylus, Batman! I followed the coin-method and, using a magnifying mirror, my Ortofon OM-30 Super stylus looks totally clean after a few dunks in the ME. I can't thank T_bone and everyone else on this thread enough. You guys rock!

I second ME efficiency on cleaning. I have got new cart which barely has 50 hours and I was using Zerodust. After applying ME the difference, even on new cart, was quite noticeable.
For those non from US, look for 3M product called Scotch-Brite cleaning pads, they use the same (as I understand and read from others comments) melamine material as ME.
