There was an article in the most recent 'Alert Diver' issue but I have not seen it online yet. DocVikingo recommended a 33-33-33 of alcohol-white vinegar-distilled water (I use 70% Isopropyl alcohol and white vinegar to come close to this enough for me when mixed 50-50).

This was the first report on ear care by Ed when he was at NEDU.
