Hi
I've been using DC#4 for years but the makers of Stabilant 22
claim better results in all kinds of environments( salt air being
the worst ).
The effects of these types of products is remarkable. I've even
used it on over heated power connectors that after being treated
never got hot or had any other issue for years. I didn't even
replace the contacts. I just made sure there was still some
spring in the socket part.
It won't fix broken sockets. Many of the style sockets that use
the folded metal strip may have failures that this won't help.
These often have a corrosion failure that happens right where
the sharpest fold is. This fold tends to fracture the plating, exposing
the inside base metal to corrosion. These socket just need to
be replaced.

Well, it reduces corrosion.
I'd say gold/gold is probably best, since it's the most
corrosion-resistant in both these senses. But whether I'd prefer
gold/tin or tin/tin depends on the tradeoffs.

We've had this thread before, but don't forget about stuff like
Stabilant 22. I had endless problems with sockets in AIM65s
(similar to the cheap sockets in a PET) installed in a plant full
of oil and other contaminants in the air; finally pulled them all
out, cleaned and treated the sockets & chips with Stab 22,
and no more problems.
Also did my PETs at that time and never had a problem with
IC sockets in them either; still running fine today.
