Anyone have a good deep cleaning technique for your microphones? I try and clean my Resound Quatros fairly regularly, but one of the back microphones is either extremely clogged or just malfunctioning. I can brush my fingers agains all the microphones and get a loud sound out of them, except for the rear right microphone. I’ve brushed and brushed with no change. Does anyone use a cleaning solution or a vacuum to clean?
Thanks for any suggestions!
