While true, the nature of the material is such that it is very hard not to use too much. After which, it is impervious to most of the solvents already discussed here. After which it is hard to deliver exactly where it may be needed.

However, if all of the above problems are solved, it is stable, non-volatile, does not harden over time, oxidizes extremely slowly (years) and so forth.

It won't. You've flushed all the lubrication out of
it.

I don't know if it's still around, but in the old days we used to be able to buy a silicone solution to refill the eject pistons in cassette players. You can also use Vaseline. To do so though means taking the control out, taking it apart, and lightly covering all moving surfaces.

I worked in a TV factory when I was young. When a batch of components
arrived from the supplier I had the job of testing potentiometers. It
took hours to get through a pack of 100. The track lubricant used by
the manufacturer was a dense fat. I've no idea what it was called but
it looked like a dense petroleum jelly. Any attempt to clean the track
ruined the lubrication. The test was just to make sure the wiper moved
smoothly before assembly continued. A component replacement cost time
and time cost money!

I have a built-in cassette player in my 1998 car.
The player froze up long ago and given all the
advice here it may be possible to resurrect it. Do
these devices have rubber pulleys?

Cassette players use 'rubber' belts and 'tires' for various mechanical
drive sections. Most of these parts can probably be found, but it will
take some hunting...
In many cases the old rubber-like compound has turned to goo and first
needs to be cleaned out. Then take out your calipers/micrometer and
start measuring! To figure out the size of the belt (square, flat, or
round) use a piece of string to work that out. Measurement is usually IC
(Inside Circumference) of the circle size of the measured string. Allow
a fudge factor and get at least one size smaller and one size larger
than you think you need to save time.

I've never had that problem.

it doesn't flow like oil, but it's easily moved by squeezing, so will get in there albeit slower. It may suffice.

However, if all of the above problems are solved, it is stable, non-volatile, does not harden over time, oxidizes extremely slowly (years) and so forth.

not only is it long term stable, but unlike most lubes it doesn't break down into corrosive substances when electrified.

Rubber belts tends to have disintegrated, less often rubber pulleys too. Cheap stationery rubber bands are often good enough, but not always.

>"** The name is WD40 - not WMD40. *

You claimed it was the same as LPS2, IT IS NOT. First of all if it smells different it is different. Also, LPS2 is electrically inert and stays that way. Not with WD40. I been to many shops, WD40 would throw the alignment off on TV tuners, you know the old type. I told them not to use it, use LPS2. Now the alignment would not drift.

When more than a very sparing amount of LPS2 is used I rinse it off with a mild solvent. It may remain electrically inert but the dust that it collects maybe not. Even if there are not say carbon particles in the environment, even dander and other types of dust, even though they MIGHT be electrically inert, they won't be when the humidity is high. If it is dander you can be sure there is is/are salt(s) in it. Much dust is dander.

 

>"Dubious that it would still be alive, much less at liberty. "

I say give him a gun and watch the fun...

 

"But it makes a great flame thrower. I think the propellant has
something to do with that. "

Hair spray is much better, but don't use it on electronics.

 

>" ** The propellant is CO2 "

Yup.

What you smell is what burns.

 

"You have two choices with Phil, agree with him, or
ignore him. "

I have a third choice, I can be fifty times as vile without even trying.

 

"To figure out the size of the belt (square, flat, or
round) use a piece of string to work that out."

I tried to do that mathematically. Like OÂşo. The diameters and distance between.

It didn't work out. (pun optional)

ANYTHING that contains oil will make RF tuned circuits drift.

They put that sh it in the shaft/bushing to get the "feel". Not in the whole thing obviously. It has a pretty high viscosity to say the least. Disassemble one like that and you see the shit is like wax.

The little radio is working so well that I'll
leave off the lube for a while. The wheel is a
bit easier to twirl now.

Maybe next time, try damping grease:

I use a similar Nye grease for lubricating microscope gears[1], which
I've also used successfully for potentiometers and controls when
necessary. The stuff is outrageously expensive, but a small tube will
last a long time. You can get a 5 tube sample of different
viscosities fairly cheap from the company. However, I suspect
ordering a new control from Sony might be easier and cheaper.
