I've salvaged a few pieces of gear from floods.
My most cherished HP RF sweep generator came out
of the mighty Mississippi river flooding in the
early 90's. *First I carefully brush off the gunk
while washing with tap water. *Then I flush with
DI or distilled water dry with a fan. *Finally flush
with anhydrous isopropanol and dry with gentle warming.
After that a bit of lubriplate on any switch detents
or gears as needed. *I take some things out first for
special treatment, like meter movements.
The distilled water flushes off the stuff we worry
about, ionic contamination and the alcohol removes
the water. *At least that's what I hope for.
I'm trying to reform and not drag so much junk home.
Sometimes I can even pass up junked hardware without
flinching. *With technical books of any sort I'm not
having much success resisting though.
Mmm! Free firewood. *Which reminds me, I need to fill the
wood shed yet. *Oak wilt disease is killing my trees but
at least I'll be warm.

Hi Grumpy: Nags me too!!!!!! (OK spot the pun?)
But got to go; to unload my pickup of a free load of firewood got
yesterday (couldn't say no to a second free batch in a week)!
Gee there were two old SPS supplies lying there too; probably all
soaking wet! I didn't even look at the old 14 inch TV lying there as
well in the junk pile.- Hide quoted text -

About 6 years ago while hauling off some junk from my in-laws home
near Jacksonsonville Fl some stuff caught my eye at the dump. There
were 3 tektronics scopes, a singer communications monitor and an audio
test set. All worked and some of the pieces had current calibratiton
stickers. Up until then I had been grumbling alot about wasting days
of my vaction time cleaning.
