Stylus cleaner


Which have you found to be very effective...?
128x128infection
Funny, I just researched this yesterday on these forums and beyond.  I needed a solution other than dry brushing, so after the research, which included talking to the people at Music Direct, reading a Michael Fremmer review, and reading some threads here, I ordered a Flux HiFi Sonic Electronic Stylus Cleaner, just last night.
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). 
Slaw: none yet!
I'll be trying the 'Dust Buster' by Vinyl Passion but I haven't heard of the ones mentioned...
How good is the Onzow & Flux?
