If severe, and the alternative is landfill - I have been known to run an entire chassis through the dishwasher (one without an exposed Calrod)

Back when projection TVs were plagued with coolant leaks, I used to soak the entire circuit board in an ammonia and soap solution. But *first*, everything that can trap water must be removed. Back then, that meant SMPS transformer, HOT and flyback XFRs, inductors,etc. A lot of work but it fixed stubborn symptoms and no call backs.

In a transistor radio, this means removing the IF transformers, audio transformer, and even removing the gang tuner is a good idea.
