Meant to add this to my earlier reply...
Since I typically slightly dampen the brush surface, it is unlikely to generate a static charge.
99 - Here are instructions I found on-line (these are also included with the device)...
"Hold the Zerostat within 12" (30.5 cm) of the surface or object to be treated. Squeeze the trigger slowly for about two seconds, to emit a stream of positive ionized air over the surface of the object. As the trigger is slowly released, a negative show of air ions is produced resulting in static neutralization. Repeat this procedure at several points across the surface of the object."
FWIW, I slowly pull and release the trigger at 3 locations above a stopped record (e.g., 12, 4 & 8 o'clock) from a distance of around 12" or so. The current instructions do seem to differ slightly from those of very early models. The very first Milty I owned included a final step in the instructions of pulling but NOT releasing the trigger above the spindle as the final step. Not sure why.
