Very nice.....

After alcohol always apply a thin coat of oil.
Solvents that remove oil or patina risk accelerated rust.
Alcohol will remove a protective coating of wax or oil
so plan to restore it.

Keep a bit of oiled cloth in a closed tin and wipe
the surface. Gun shops have special purpose
rags with silicon "stuff" to the same end. Common
pharmacy grade mineral oil is a good choice. Special
attention to the pivot can keep it clean.
