Cleaning receiver circuit board
I'm in the process of restoring a Kenwood KR-4070. The power switch was the first item to be replaced. The next item to be addressed is a complete cleaning of the whole circuit board. It currently has a nice coat of dust and grime all over.
Any suggestions on how to go about a wholesale cleaning? I'm tempted to just dunk the whole unit into a big bucket of isopropl alcohol to get all of the grime off.
