Calling all electrostatic speaker owners

Thanks for the responses. My speakers are ML Aeon i, about 3 years old. I live in a first floor apartment, over the leasing office. The UPS / FedEx / Comcast / etc diesel trucks park every day with idling engines, and since I leave my windows open most of the time, the apartment is fairly dusty. Dry northern California summers contribute to this also.

I have definitely noticed reduced output for a given volume input, as well as a loss of clarity in higher frequencies. Looks like it's time to break out the vacuum cleaner.

Will try vacuuming this evening. Tried closing the windows, but the place heated up and I had to run the a/c - very noisy. Will have to live with the dust, I guess. :(

I recall a thread here some time ago written by someone who cleaned his panels in the shower. I don't smoke, so my speakers don't appear to be that gunked up, but interesting to know the panels can withstand that kind of cleaning.

Thanks again, everyone.
