Sorry for the smarty response. I was just feeling a little sassy or not sure what exactly.

OK on a serious note. I would advise that any cleaning is done with pure water. And yes the water must be completely removed before applying power to the radio. Water is used as a flux cleaner for the water based fluxes used in the soldering process. Water will not actually hurt any of the electronic components, except for things that might trap water inside such as motors and some switches and relays that are not sealed.

So the unit must de dissasembled and flushed with water and then completely dried. I would not recommend solvent type cleaners since they dont do a good job of disolving sugar and milk etc. Water is best in this case.

To make up for my sassyness, I would be willing to service your radio if you send it to me, free of charge of course.. I once had a career repairing consumer electronics. So I have resurected many radios that suffered the same fate.

I wish you luck.
