Are There Any Risks to Your Stylus From Using Magic Eraser

I use Furutech SK3 brush after each play and Lyra SPT only sometimes and my cartridges last for years.

Noromance, that is all marketing crap like "jitter"  All that stuff just causes tracking distortion which is not sibilance. Sibilance can occur with any program source including all digital sources and it has to do with our ears sensitivity in that frequency band. I can erase it immediately with a 3 dB notch filter centered on 3000 Hz. If you had the ability to digitally modify the frequency response of your system at will you would know this to be true. I have that ability and can demonstrate this to anyone in a heart beat. Also I am not trying to sell anything to anybody and because I no longer work in the industry I do not have to be politically correct. I revel in being politically incorrect. Soundsmith unfortunately persists in perpetrating a lot of mythology which is probably the major reason I don't have one of their cartridges.
