Did I damage my cartridge?

I had the same problem with an Adcom HO MC after repeated use of Stylast. After it was returned to Adcom, they called me to say the Stylast plus gunk was up in the cartridge, and it was causing the fuzziness. They sent me a new cartridge, though it was my fault for using too much.

You might try one of those canned air dusters blowing toward the top entrance to the cartridge. VERY CAREFULLY!
Otherwise, Theo is probably correct.

Listener57, is it possible to clean the gadget itself, or does it just keep accumulating more gunk until it's totally shot?

I have read that you can clean them, I forget the specifics, the article was in one of my Audio magazines.

Zaikesman, Philjolet is correct. There is a tiny "instruction sheet" which tells a recommended way to clean the Zerodust, so it is usable indefinitely.
I still use Stylast, and have been lucky it has not created a problem for me. Maybe, the Zerodust gel disc which resembles a tiny round pillow, also collects any invisible Stylast residue after each playing, so Stylast does not build up and travel up the cantilever?

Well, It looks like I may have messed up. I pushed the stylus down in the pillow with light force. I most likely through something out of wack.
