Barrel rust removal from a rifle

I used Kroil once to loosen-up a beautiful Borchardt that had been stored for years and was "frozen-up" to the point it couldn't be dismantled. I simply removed the grips and then submerged the entire pistol in a container of Kroil for three days. After the extended soaking I was able to completely dismantle the pistol for cleaning. The only thing effected by the soaking was the crud and what little rust there was. The bluing was not in any way effected.

An old trick I have used for years is use oven cleaner on a warm barrel let it set for awhile. And use a cleaning rod with stiff brush attached to a drill motor and have fun going at high R PM's. Amazing results.

So long as you catch surface rust early on, treatment with most gun oils and very gentle abrasion to remove the rust (but not the finish around the rust) has worked for me. I have both brass brushes and some stiff nylon brushes that have taken care of all my issues.

How do you get into areas the brass brush cant get to? There are a lot of nooks and crannies on these lugers that I can't get to

Disassembly, completely if needed instead of just a basic field strip. There are plenty of internet videos to help if you are unsure how to.

If you do a search you will find several threads/references to using 0000 steel wool with oil and light pressure to remove rust from areas other than the bore.
