This may have been handled here before but if so I can't find anything on it. Has anyone ever cleaned the heat exchanger internals of their Harman Accentra insert? If so, how? Had mine for going on six years and though I've cleaned it thoroughly many times I can't find any information on cleaning the heat exchanger internally. There is no indication that it is in any way clogged but if possible I'd like to do it.
Suggestions?
