James R.,
The engine starting fluid generally contains other petroleum additives which may be worse than the lube in tuner/control cleaner.

Starting fluid, ether, does a good job. Fumes alone get into place and clean contacts. Do not use anything cleaned with starting fluid until it's completely evaporated. I use it but seldom mention starting fluid as it catches fire easily. Do not use it around a heater with pilot light.

:Is there a good cheap cleaner for tube sockets. I noticed that contact cleaner is about $20 a can and tuner cleaner has a lube in it which I might not want everywhere. I was thinking about ether(starting fluid) or brake parts cleaner. They are only $1.99 /can.
I have used starting fluid for years to start diesel tractors, especially in cold weather. I have also witnessed other uses for its explosiveness in the construction area--extremely dangerous and definitely not on the OSHA list of safe practices.
By the way, there are at least two different kinds of starting fluid, ether and one containing petroleum distillates and no ether. The last can of starting fluid I purchased was the latter, much easier on an engine, but also not quite as effective in starting the engine.

James,
About the cheapest thing that you can use is rubbing alcohol on a pipe cleaner. You can buy pipe cleaners with fine wires embedded in the floss that will do a really good job of scratching out any corrosion. May be hard to find any place but a tobacco shop. You can also use MEK available at a hardware store. Remington rifle bore cleaner contains a mild abrasive and might work good too. Just dip the pipe cleaner and swab away.

If you happen to have a Advance Auto near you , they sell the large can (14oz) of the CRC electrical contact cleaner for less than 5 bucks, this is also flammable but evaporates quick like alcohol, I have used it and it works good.

I use a contact cleaner (about $10 a can). But my secret is to use a small brush, which I work into each socket. This combination really gets em clean.

Upon inspection of the area closest to the bottom onf the glass envelope, one is typically going to find a dark oxide encircling the pins.
Tube socket construction varies in the respect of their clinching action.
One type almost completely encircles the inserted pin....~75 percent.
Another type of construction has two opposing semicircles that effectively contact maybe 25 percent of the pin.
The last unit is the common wafer socket with its two hoz planes that spread apart and probably touches but 10 percent of the pin area.
For immediate analysis, one can merely unplug the tube and reinsert and hope that some degree of cleaning was initiated by the scraping action.
For the surest action, I always reserve that to be attained by pulling the tube and initiating side to side overlapping scrapings...(on the longitudinal axis)...of each wire pin using an Exacto knife with its # 11 blade.
A final application of DOW Corning Z5 silicone grease applied with a fine artist brush leaves them in a protected shield. Free, even from tube heat sag /run off.
