What is the correct way to use the Zerostat?

...and don't do something foolish like press your finger on the tip of the gun to test if it's working, it hurts like hell.

Release the trigger slowly. Don't just let go. I take up to 5 to 8 seconds to completely released the trigger. You can hear it.

Can it damage cartridges?

Audphile, I haven't read every single post that followed on to your first one, but if you use the (old style) Audioquest brush AFTER you use the Zerostat, you are likely putting static charge back on the LP after you neutralized it with the Zerostat, whether you moisten your fingers or not, because the old Audioquest brush provides no electrical continuity between the bristles and the handle.  Zerostat treatment should come last. (There IS a new Audioquest brush that is grounded via the body of the user, by holding its handle during use, thus perhaps it does not create a static charge on the LP. I don't know when the new version of the brush came on the market, but I think it is quite recent.)

I don't argue with the notion that the LP should be sitting still, not rotating, but I do not understand why that would be the case.

I’ve changed my method to the three point plus center.... wow. This thong finally works as I’d always hoped it would.  Thanks audphile.
