If you can take the chassis out of the radio's case without too much
trouble,wash the case throughly a few times and let the chassis sit in
an airtight container with baking soda.No guarantee you will ever get
rid of all of the smoky odor.Cigarette smoke is very bad for electronic
parts in radios,computers,all kinds of electronic thingys and it can
greatly shorten the lifespan of all things electronic.
