last stylas cleaner is safe, last stylas preservative is questionable.
I am always open to the possibility of a cleaner or technique doing damage, but still to this day, I have yet to hear of anyone having a problem with the last cleaner.
I evan clean up and inside the armature occasionally on my clavis dc (this is against lyra's instruction) and to me the sound is just like new as far as I can tell. I onced used it to unclog thick dustballs that were cloging another lyra, so the whole cartridge had to get this stuff on it, including the coils and rubber and any glue (this was taking a risk, but the cartridge was actually clogged to the point that I would have to have sent it in to be at least partially disassembled!?). It worked. That is to say, it disolved the grime and the cartidge sounded good without mistracking or any evidence of loose parts.
That's my experience of how I have taken this stuff to far.
Don't take this as the know all end all of cleaning with last, but rather good solid evidence that it should not clog or leave a film under normal use.
