Yeah, I agree. There are a lot of factors involved. I
mentioned in my first post when speculating why my SW-54 is in such better shape
that it could be where the rigs were kept all these hears, regional factors, how
the chassis was treated before plating, and lots of other things. I suspect the
Drake engineers who spec'd the copper plating process were not considering how
the rig would look 40+ years later.

Possibly. Obviously, it is not possible to seal up the rig. My reasoning was
that the inside of the rig is going to be close to dead air when the rig is
cold allowing that air to be more saturated with the chemistry involved.
When the rig is on, the heated air will rise and any contamination in the
shack will not remain in the enclosure long enough to do any damage. We
could go round and round on this, but I figured it's worth the try...and
it's free.
It might even be possible to figure out what is needed to grab the sulfur
and other contaminants out of the air. Maybe a chunk of something more
aggressive than a wimpy little paper strip would be needed. I don't know.
I'd be interested to know why all three of my Drake rigs have much more
corrosion than my much older SW-54 receiver. Maybe the SW-54 spent most of
its life packed away in a sealed trunk. Or maybe it lived in a less polluted
region of the country for most of its life. Or maybe the copper plating was
higher quality or thicker. Or maybe the underlying steel chassis was treated
in some different way first.
I enjoyed hearing about the chrome plated DX-100. Before reading that I had
given momentary thought to how one might carefully remove all the components
from, say, a 2-B and having it replated. Maybe when restored 2-Bs are going
for a couple of $kilobucks on ebay I'll consider it. For 150 bucks, its
easier to just use the receiver and not look inside the cabinet too much.

Those strips may not work so well unless you seal the rig in an air-tight
bag. A friend of mine makes jewelry out of silver and she puts those strips
in little ziploc bags for the reasons we're talking about here.
But if you don't keep the bag closed the strips don't help :-(
hope this helps......
