Calling all electrostatic speaker owners


What are the sonic symptoms of a dusty electrostatic panel? Is vacuuming the best cleaning method?

Thanks.

be careful to run the brush from the vacuum in one direction starting from the frame so that the bristles bend and do not penetrate the panel, dont change directions with brush to avoid same problem.
Great info above. Question for you guys. Can I paint the electro static panels and not change the sound? Or will the paint destroy the sound? 
The paint will destroy your electrostats. The panels will no longer hold an electrostatic charge.
