I have a Sterlingworth Fox from the 20s that I've used and cleaned for 50+ years in the following manner:

* Multiple passes with a 12ga bore brush soaked in Hoppe's.
* Scrub each barrel with patches again soaked in Hoppe's until clean.
* Wipe the residue out of each barrel with dry patches.
* Run a patch with gun oil down each barrel.

These barrel look no different to me then they did when I acquired the gun over 50 years ago. The barrels still look brand new.
