For the last 30 years or so, every beat up old S&W target gun that's come to live here has been treated to "Ralph's Bath".
The gun comes ALL apart (except for barrels and action studs). Every thing goes to soak in Mineral Spirits for 2-3 days---longer if I have other fish to fry. Then all the bits, pieces, nooks, crannies, and screw holes get scrubbed to within an inch of their life----and rinsed with clean Mineral Spirits---and dried with DRY high pressure air (100-125 PSI).
Then they get hosed down with CorrosionX, and left to soak for 2-3 days---or however long it takes me to get back to it. As much of the CorrosionX as will come off gets blasted off with DRY high pressure air------and everything gets put back together.
The remaining CorrosionX on the exterior get wiped off with Hoppes #9 on a clean cotton cloth. The gun gets dried/polished with another clean cotton cloth, and goes to live with its friends in a large display case.
The case is not air tight, so the guns get the dust vacuumed off of them about twice a year.
That's it---there ain't no more! A whole bunch of guns have been sitting in that display case for upwards of 30 years, and have come to no harm whatsoever.
Now let's talk about fishing tackle. Most folks will tell you fishing tackle is made to catch fish. The fact of the matter is fishing tackle is made to sell to fisherman. So too is any/all super-whiz-bang gun storage stuff made to sell to paranoid gun owners----except for CorrosionX. It's GOOD STUFF!!
