I have two portable radios (one a Superadio II) and another is a Circle of Sound Zenith clock radio. Both of these radios are extremely dirty and i'm cleaning them up.
I've cleaned up the Zenith and have it working 98% except for one minor thing - the tuning condenser. It crackles like a dirty pot when you tune across the lower half of the AM and FM bands (more pronounced on the AM).
Since these little things are very difficult to repair (they're not like the open air capacitors where it's easy to bend back the plates properly if they're touching.
Could it be dirt and dust inside the capacitors or can it bent plates? Would a shot of volume-control cleaner spray clear out the nasties or will I have to replace the condensers? I bought two new ones just in case....thanks all!
Tuner cleaner may work, you might also try applying just a drop of "Rail Zip" on those areas where you can get at that area of rolling contact.

What is rail-zip? And where can I get it?
Many thanks!
