I see this question often, but immediately think..."Why does it need to
be clean to reuse it?"
It's the outside of the connector. Whether it's covered with tape,
compound, or hot glue what difference does it make? I have lengths of
coax that have had their connectors weatherproofed time and time again,
yet I never bother trying to clean them up unless it's something that
will interfere with the next weatherproofing process.
I rarely reuse (take them off one piece of coax and reinstall on
another) connectors unless they are the big expensive ones used on the
LMR-600. Remember that by the time you've connected and disconnected a
UHF connector 40 or 50 times you've used a substantial portion of its

As I said in the first paragraph, why worry about the stuff stuck on the
outside if it doesn't prevent you from weatherproofing the connection again?
You can reuse it until the connector fails.
