Cartridge cleaning

The Zerodust cleaner is an EXCELLENT cleaning product if you are afraid/skeptical in using a liquid based product.

Yes, this is a topic that has been debated a lot on A'gon! I'm sure the other experts will chime in shortly.

Meanwhile I have the Discwasher fluid & brush. I use the fluid very, very, very sparingly (for the fear of having the fluid run up the cantilever into the coils & magnet system). I have found that most of the time several gentle brushes with *only* the Discwasher brush gets the stylus clean. I shine a flashlight on the stylus & observe if I can see light thru the stylus. If affirmative, the stylus is clean. If not, I use a stingy drop of Discwasher fluid & repeat the cleaning process. With a bit of fluid I can get the stylus clean to my satisfaction.
I do not have personal experience w/ the Zerodust product but my friend uses it. I personally do not think that it scrubs the stylus clean enough. It seems to be good for in-between LP plays but not for getting off the black stuff that sticks to the stylus over several LP plays. Of course, JMHO. FWIW. YMMV.

I've had the Helikon and now a Lyra Argo. Jonathan Carr of ScanTech who designed the cartridge and the distributor, Immedia, both recommend the Lyra SPT liquid cleaner and NOT the Zerodust.

I've used the Lyra SPT for two years and never a problem. Just take your time and use as directed.

I use demineralized water.
