I stopped using ZeroDust a while ago. I use the brush that was included with my Hana cartridge and go gently to remove the dust from the stylus. I use MoFi LP#9 after playing a dozen or so records.
Anyone Still Using Zerodust
Haven’t heard anything since the original scare, but I stopped using it. I think I never had a problem because I always swipe with LP#9 between sides, as per Brooks Berdan’s advice. One recent video said Wally discovered some type of oil on the ZD. I regularly cleaned mine with dishwashing liquid, which could have removed any residue.
