I know the older guys will get laugh,but (for us new guys still learning the tricks) just found that Tarn-X work great for cleaning all the brass & copper elec.ends an connectors.They come out looking new!
Hope,this helps someone out.Bill WY

Be aware that many copper and brass cleaners leave a film of an anti-tarnish component to inhibit future tarnishing. This may or may not interfere with electrical conductivity so just to be sure I'd give contacts so cleaned an extra cleaning with some solvent designed for cleaning elecrical contacts.

A standard of the electronics industry is a contact cleaner called DeoxIT, which dissolves connector contamination and leaves a light lubricant protection that does not inhibit conductivity. Deoxit is manufactured by CAIG Laboratories and is available through electronics and maintenance suppliers.

G'day 40clubcoupe,
First post, although a PackardInfo member for a fair while, so

And I invite you to include your '40 Club Coupe in the Packard Owner's Registry here on PackardInfo!

I use a product of CAIG labs for cleaning and lube of copper and brass - good stuff.

I use a polish called Met-All for brass and copper. I started using this to polish brass lamps and things on brass cars I use the aluminum version of Met-All and I don't believe it leaves a film. I buy this in one pound tins I get from aircraft supply places. I usually wash a small part off in hot water and dish soap after I polish it.

I use Meguiars #20 for all plastic material.

I do not use WD40 for a lubricant although it works nice to clean up a painted surface. I wipe down the black crackle finish on the motor of my Harley and it looks new until I get it muddy.

WD-40 cleans up all kinds of painted surfaces and it does leave a residue which hardens.

I play with things like antique radios, clocks, and other mechanical things and I use the above for most projects.

For clocks and similar, I only use appropriate lubricants with accepted practices.

I have used lubricants in a spray can for larger mechanical things.

Jim, the first time I saw WD-40 being used to clean the body of a car was at an SCCA Grand Prix in Dallas, Texas many years ago. Tom Walkinshaw (sp.?) had two 5-cylinder turbo charged Audi Quattros in the race. They could go anywhere on the track at any time. They just out drove the competition, including the late Paul Newman, who was driving a Nissan V-8 powered Z-car. They won first and second places. After the race my brother and I went down to the paddock area and watched the pit crew clean up the cars using WD-40. I still use the stuff to clean painted surfaces in the engine compartment and chassis. I do not use WD-40 as a penetrating oil. Thanks for the memory.

The CAIG product is CAIlube M260cp. I use it on toy train armatures and they show marked improvement.
