Corroded wave guide
Corroded wave guide
(OP)
I am working with the military. The soldiers left their spare waveguides out in the elements. A massive amount of corrosion has built up both inside and outside of the waveguides. Replacements will be a long time in coming. Any suggestions for cleaning the corrosion? Any suggestions for coating to stop future corrosion? It looks like there was a lacquer on the wave guide before. There is pitting. I just need to try to keep this all functional till replacements arrive.

For a simple physical cleaning, get a long string or monofilament fishing line, use a block or smaller waveguide that fits inside your larger waveguide, attach scotchbrite to the smaller waveguide and pull it back and forth to clean out the waveguide. That still may not work to clean it if plating is corroded away from the inside of the waveguide for low loss. You'll have to measure the loss and hope you don't have very high power going thru it, arcing is fun to watch, but harmful.
Good luck soldier,
