[Elecraft] [K3] Keyer Pause

[Bob]

Craig Labs the maker of DeoxIT also has a specific product for gold contacts.  Here:

http://store.caig.com/

I have not used it so can not comment on it.   I do use their S-Shield but my 
old can is labeled
PreservIT.  I use that on all coax connectors and have never had a problem with 
any connector
that had it applied.  Using it *may*  extend the interval between cleaning or 
eliminate the need
for further cleanings.

NFI & YMMV
