doof, these pots are extremely hard to come by. Not only is
the spacing of solder pins not found on any currently
manufactured pots, but the shaft-length is also an odd size.
A few hours of research and you'll come to the same
conclusion.</font></blockquote>

convenient shaft opening and work the wiper over the wafer
repeatedly. Yep, the pot doesn't even need to be disassembled as
the wiper assembly is clearly visible through a small
opening. Just solder those old suckers right back on. For
future reference: don't desolder if there's an easier solution.
The OB-8 pots can be cleaned simply by removing both pot pcbs (held in
place by about 12 hex nuts).</font></blockquote>

<div>Not to sub up and start criticizing, but cleaners with lubes are
generally a bad idea.</div>
<div>You want to flush out what's in there. Any good solvent will
remove a lube though.</div>
<div>Flushing out a pot with a cleaner and lube mixture will result in
lube on the pcb, attracting dust and causing increased capacitance and
lower resistance paths. Really bad for high impedance circuits.</div>
<div><br></div>
<div>Usually when this type of service is attempted, the pots work
great at first, gather more dust over time and fail, worse than
before, sometime later. There's a reason that pros don't go to Radio
Shack and this is one of them. There is no magic elixer or miracle
juice and if there is, it doesn't have Radio Shack or Caig on it's
label.</div>
<div>Fwiw, you could spray cooking oil or WD40 in a pot and it will
quiet it up, but it's not the right thing to do either.</div>
<div><br></div>
<div><br></div>
<div>Sorry for the opinion. This is all I do.. everyday... for
years... decades.</div>
