The volume control of the cheapie Sony "transistor" AM FM radio I
bought about a year ago does not operate smoothly at low volumes.
Could I try spraying it with something, and if so, what do people
recommend?

Even if not cost-effective, I hate to throw things away. Further, it
has the best FM performance of any small radio I have ever had.


Why does no one ever seem to mention desoldering the pot and taking it
apart. Then you can actually see whether it is wear,dirt, hardened
lubricant, weak wiper springing or misalgnment, bad paxolin rivets,
cracked
paxolin etc.


Because its best to look on the bright side till all else fails.




As something in excess of 95 percent of the "dirty" pots I come across are
anything else but dirty, I've long since been in the habit of removing and
dismantling rather than wasting time with various potions.


Absolutely, pots that don't get 'twiddled' much might be dirty but a
volume pot is prone to being worn 'out'. Sometimes a little bend of the
contact wiper to an unworn part of the track (on older pots) can extend
the life.
