Milty Zerostat 3 Completely effective at neutralising static charges on virtually any surface without the need for sprays. The Zerostat 3 is highly rated for its ability to improve the sound quality of records and CDs by harmlessly removing static. The Zerostat 3 incorporates a unique piezo-electric crystal device which generates a powerful stream of negative ions with one gentle squeeze of the trigger, and an equally large positive stream on release of the trigger. In this way the negative charge, on a vinyl record for instance, is harmlessly swept away. Constructed from durable hard plastic, it requires no batteries or refills and when used in combination with a Goldring cleaning brush will keep your vinyl collection dust free.
