Contact cleaners ( for you old timers, Tuner cleaner).
This particular product line used to be known as Cramolin
company is now CAIG
They make a line of cleaners/lubes and protectants under the DeoxIT label
http://www.caig.com/
http://store.caig.com/s.nl/sc.2/category.188/.f
is the common red label can
==============
another less common source of specialty cleaners and chemicals is
http://www.miller-stephenson.com/
they have several useful products
while it is not a contact cleaner, I use a TFE spray on a lot of the things
I do
MS-122 is a dry release agent for mold processes, and is an excellent dry
lubricant. I have used it successfully on the 3 inch hairpin jumpers in
our antenna patch bay at some 40 KW and it does not accumulate dust and
dirt
I also use MS122 on the tuning sleeve and shafts of UHF cavities when I
rebuild them - they tune much more smoothly afterwards- years afterwards
MS-124 is a connector lube that really makes life much better with
multi=pin connectors, but does have some residue that can accumulate dirt
at the wrong time
between these two manufacturers, there is certain to be a contact
cleaner/protectant applicable to your task. Just be sure to read
carefully- one of the things Tuner Cleaners would do - since they had a
light oil in the mix- is to soak into the wafer in phenolic wafer switches,
and then attract dirt- with an ugly result after a few years.
Never use a residue cleaner on a ceramic wafer switch (think Tektronix in
the 60-70s)
