Electrets need heating in order to be "electr-rized."   I vote for ions.


Ah, I remember: Richard Hull of TBCOR did some experiments with this stuff.

It's very difficult to take the surface charge off an insulator.  The
usual method is to bathe the insulator in air with + and - ions (with AC
driven needles, or with a radioactive rod), and let the surface charges
pull in just what they need to become neutral.  If the charges had already
buried themselves within the material, it takes awhile for neutralization
to complete.


Hey!   Pranking possibilities!


If you coat a plastic bottle with negative ions, then fill it with, say,
cola, if you wrap your hand around the bottle, when the liquid touches
your mouth, POW.     Hmmmm.   Maybe I should have kept that idea secret.

Take a look at:
