Using the Magic Eraser with the SL 10 tonearm in the lid is tricky and induces the "chill / fear" of the proverbial cleaning utensil vs cantilever / stylus faceoff.
I run a couple of SL-QL1s and I am surprised to see:

after a period of playtime, even with dust lid closed and a swipe of the D4 loaded with homebrew fluid on every LP.
When I notice distortion, especially on the inner grooves, I know it's time to take the cartridge out of the arm and use my blunt tipped artist paint brush and clean the stylus with a solvent. I then view my cartridge / stylus under the kiddie microscope to visually verify cleanliness / wear then reinstall. Voila, nice clean sound.
With a conventional tonearm, dipping the cartridge onto a ME is quite easy. The automatic features / overides of the Technics linears and the current tt mountings in the audio system make the delicate wielding of a Magic Eraser impossible for me.
As always Your Stylus Cleaning Adventures May Vary.
Good luck.
