The reason I use the Zerodust after the Magic Eraser is that the ME may leave microscopic white particles on the stylus that have rubbed off. The Zerodust gets these off the stylus and they stick to the goopy surface and can't become airborne. A strandard stylus brush may wipe the particles off the stylus BUT if they become airborne, I would hate them to settle on the vinyl LP surface to reek untold havoc in the grooves. Perhaps I'm being overly cautious, but I agree with Doug that the Zerodust used alone does an inadequate job of cleaning the stylus.
