Try some WD40 or similar spray lubricant - seriously bet it makes all the

That works, if you don't mind doing it again in about a month. The
residual oils left behind by WD-40 seems to turn to sticky gum. Try
it yourself. Spray some WD-40 on some glass and let it evaporate.
Check the oil after a few weeks of exposure to air. I used some
microscope slides with various contact cleaners. Only WD-40 became
sticky. Note that the "electrical contact cleaner" term was removed
from the WD-40 can at some times in the 1970's. The company also
introduced a product designed specifically for contact cleaning, which
contains NO oils:

If you want to break loose frozen controls, I have no problem using
WD-40. However, for contact cleaner, I use something else.


I have in my mind, a tv tuner on the WD-40 can. Am I right ?

My preferred general purpose spray is CRC 2-26 .
I know that says, improves electrical properties, and plastic safe.

I used to have a lot of problems with volume controls in the desert. Sand?
Also have a can of Blue Shower, with the dohickies in it. I never much used
it. I bought one of the last cans.

The really cool thing about CRC 2-26 . If you just gently push the button,
it foams out of the nozzle, filling voids very well.

I've used most everything. Used more WD-40 over the years than anything.
I also have used Cramolin Contaclean. It has made pots so sticky, they will
not turn. You got to flush that stuff off, like it says on the can, after
cleaning cycle.
