Do NOT use WD-40!!!. I'm not familiar with PUREtronics stuff, but I use
Chemtronics 'Tun-O-Wash' for my applications and it works great. The best
stuff you can use, if you can find it, is Cramolin R-5. And Glenn is right
too...the color TV tuner cleaner at Radio Shack works pretty good too.




Caig industries also makes a good product called DeOxit. What's nice
about this product is you can get it in various concentrations and delivery
methods. I find the 5% spray can works fine but I've heard the 100% in
a dropper works great, too.

You should see what it does for model trains!

Best stuff ever saw for cleaning contacts is a liquid freon spray-
It is clean enough to use on a telephone switch, non toxic, and
removes grime quite well- Problem? well, 1) the stuff is banned in California,
2) you have to be a service shop to buy the stuff! There originally was a
Motorola service notice for the problem of "Fretting" in plugs and sockets.
Use the freon spray, then use an inhibitor that AMP makes. Allows good contact
yet, prevents oxidation/dirt build-up. Think the Freon spray was from INTERTECH
(been few years ago, when I retired) You might be able to get a nearly empty
can from a service shop, for a moderate price. They even had a minature scrub
brush for the freon spray! with about 12 inch hose, and a spray nozzle contained
a small brush like the one you would use to clean the head of a electric RAZOR!.
Worked quite well, as I remember. Might also be available at TALLEY industries.
For normal person, full can would probably last several lifetimes.
