Fully discharge a metal plate?

[hackhard]

is there any way to fully neutralize a charged metal plate ?
connecting it to metal body of relatively huge capacitance will make its charge negligible but not zero?
is there any other way?

High humidity in the air will help to discharge any static charge to the environment and ground...

Perhaps repeat the process until there is a high probability of the charge being less that that of a single electron?

I think you first need to define how you will measure the charge.
