Well, I do everything wrong. I use Hoppe's No. 9 (yellow label) and a stainless steel bore brush of correct caliber. I use an undersize jag for the caliber and soak a patch with Hoppe's and coat the bore good with that. Same for the chambers. I let this set awhile and dry the chambers, then make about ten passes through the bore with the stainless steel bore brush. Finally dry the bore. I use a 50/50 mix of automotive motor oil and Three-In-One oil, oiling the bore and chambers with a light coat. Heavily oil the exterior, then wipe it down with a blue paper shop towel, the kind sold at AutoZone.
I know this will soon wear out my guns, but I only expect to last another fifteen years at most, so my guns, which are about fifty years old in some cases, will probably last that long.
I will soon have had this gun fifty-five years, and put just over 17,000 rounds through it.
It's been cared for in this way ever since day one.

P.S. Given my family history, I might last another twenty-five years.
