Ultrasonic vibrations? I kid... I have a Makita air blower/duster, I love that thing and use regularly, just not at full blast and at an angle with one of the wide nozzles as not to create any flutter/flap in the driver or blow directly into the center. Then occasionally I'll bust out the Miele micro-brush set (sadly discontinued) on the lowest setting. For the cabinet, Pledge or a hippy cleanser like 7th Generation or Method, use blower first, then spray cleanser into rag so you avoid getting it on the driver, then use the rag for wiping down the cabinet, then use the blower to dry it off. What do you listen to, by the way? Do you like Huey Lewis and the News? Their early work was a little too new wave for my taste. But when Sports came out in '83, I think they really came into their own, commercially and artistically.
