Contact lens cleaner for cleaning stylus cartridge ?

Lens cleaner should be fine, alcohol is fine. But I wouldn’t do this often. If stylus is getting dirty fast, focus on cleaning the records.

I don’t remember the last time I cleaned my 2M Black. I play every day and the stylus looks like it came out of the box new.

If it does become slightly dirty, simply playing one side of a new record gets it looking new again.

Avoid blu tack and magic eraser at all costs!

Liquids are not harmful to the stylus itself. However, they can have detrimental effects on adhesives applied to the cantilever and cartridge body. 

Magic Eraser and Blutack are excellent cleaners if used correctly. Ignore those who dismiss either or both. 

thom, +1 for the Magic Erasure / Very effective
