All: Seeking advice on a cleaning solution for N-connectors which have been stored on cable in a barn and show a little verdigris. That is, they have been protected from direct rain, but not ambient humidity.
I considered some TV-tuner and control cleaner I have here, but that leaves a libricating residue with unknown effects on dielectric behavior, etc.
Surely somebody's been thru this before!
Any suggestions?
(Yes, I'm digging out stuff for the FD satellite station . . ..)

Hi Jim,
Acetone should be the solution to your answer.

PC board cleaner/component cleaner, tuner cleaner without the silicon lubricant, works well. Lacking that, follow up with an acetone and/or 90% alcohol solution, and then put it out in the hot sun, or a hot air blower, to dry. Some will wick up the coax, but the vapor pressure is so high it will evaporate rapidly.

PS Only a Navy man would know the word "verdigris!"

Hi Jim, WB4GCS
From GORE-TEX microwave test cable
CLEANING
DO:
First try compressed air only Use pure isopropanol with cotton swabs Clean connector threads Dry with compressed air
DO NOT
Use any abrasives, chlorinated solvents, or lubricants Get isopropanol into plastic support beads Blow into connectors Tap connectors to remove debris

Have you tried White Vinegar? It does a good job on cleaning glass without streaking-no residue. Also, vinegar is used to pickle metals befor painting. Just my two cents worth.

From what I can remember of school chemistry vinegar is acetic acid which
reacts with copper. 73 john g7hia
