Cartridge cleaning


There is a lot of information in the forums reagarding record cleaning and preperation but, little about the art of cartride cleaning. In the past I always used the discwasher stylus cleaning solution and brush. Now I have a Lyra Helikon cartridge and the paper dust cover has made me afraid to use a liquid.
What are the accepted cartridge cleaning rituals among all you more experienced than I? Is the Zerodust cleaner a good product?

I use a Zerodust on my Orotofon Jubilee - works great. Ocassionally, I use an old (circa 1985) Signet SK305 electronic stylus cleaner, with a very, very small bit of Last stylus cleaner. That also works great.

Here's a tip (assuming your records are squeaky clean to begin with) - use a carbon fiber brush (like an Audioquest) on each LP side *both* before *and* after each play - - since following this procedure (for a couple of years now) my stylus stays much, much cleaner longer - - which means less use of any cleaning agent/mechanism applied directly to the stylus.
I agree with use of carbon fiber brush before each play, but have not used after each play by personal habit. I have been impressed how much the Zerodust collects from the stylus which I do clean before and after each play. Very simple compared to use of Last stylus cleaner with its brush. Bombaywalla's idea to see if light passes through the stylus seems quite clever, and I'll have to try it. Hope it doesn't force me back to wet cleaning again.
Light passes through my stylus easily enough, although the color is more amber than clear. Does this seem right?

The ExtremePhono stylus cleaner works alot like the ZeroDust for a substantially lower price. I'm too terrified of breaking my cantilever to try Tom's match striker.
