I have had a couple of DL103 cartridges, and I always use the matchbook striker method of cleaning them. I have never used the liquids, so I don't know about them. I have heard that they can "wick" up a hollow cantilever. I think that there is a type of dry cleaner that you just lower the stylus onto, and it cleans it without applying liquids. I forget the name of it. But using a matchbook striker on the contact surfaces has always worked well for me. I use that on all my styli, and have for years. No damage. Linn recommended this method for years.
