Magic Erasure can leave fibers in the stylus where it connects to the cantilever. Some "wet" cleaners may attack the bond between the cantilever and stylus (I don't want to experiment).
Like sksos1, I use Bluestick (BlutTak or similar) pressed flat on a quarter using the same technique as described. I've used that on carts from AudioTechnia, Lyra and rebuilds from Soundsmith. Does a good job.
Also use it on a stylus between plays an someone else's home with very good A/B comparison results.
