You cannot get away with having a perfectly clean stylus all the time, tiny deposits on the playing face of your vinyl will be dragged up and stored on your cartridges stylus, affect sound reproduction , damage your precious LPs and shorten the life of your cartridge.
Simply move the tip of this brush gently under your cartridge from the back to the front to clean your stylus.
You'll hear less noise and distortion and you'll protect your investment. Always brush from the back of the stylus (the end nearest the cantilever) towards the tip.
NEVER side to side, never front to back.
