I use a thin sliver of Magic Eraser and just barely touch the stylus before each side.
15 years on and no problems. The stylus is spotless . I also US clean all albums I play and brush each side off before playing
I sent a cartridge in to one of the rebuilders to have a look at it after a couple years of using it because I had bought it used and had untold hours on it. So figured it was time.
He said the stylus didn`t need replacing at all and that it looked very good.
Really appreciated his honesty.
