I would use caig deoxit. They have a version that has lubrication properties. I
think it is the "S" series.

The rivets are likely more of a safety thing than an issue warrantee repair
thing. The inside of a Apple II is intended to have user access. The switching
supply has 300 to 400V DC inside. Definitely a potential lethal hazard.

If the contacts are gold then I would suggest Caig ProGold followed by Caig
Shield S5. Use sparingly as it’s highly conductive and may lead to some
strange results from spraying it too freely.
You might also consider one of Caig’s Non-Conductive Buss Lubricants.

Last year I created an LK201 keyboard emulator that uses a USB keyboard.
More recently I extended that work to create a second one that uses a PS-2
keyboard instead. Partly because I had one and figured it would be fun to try.

We used to use DC #4.
As an example, I had a ZX81. I added a RAM pack and had to be real careful
about wiggling or moving the AX81. I put DC #4 on the pins. One could drop the
computer with the RAM attached and it wouldn't lose a bit.
I don't like deox as it has chemical actions that continue ove

MIT, by Dick Waters, and another from SAIL, by Bo Eross. They run fine
on SIMH, but it would be nice to see them on real hardware too.
