Re: Your opinion on best method to degrease a gun?
Theres a bunch of products (breakfree, denatured alcohol, mineral spirits, brake cleaner etc) that could be used on the metal parts. It's best to COMPLETELY disassemble and soak parts. If you need to, take pics to help with reassembly. Use an assortment of tools to get into all the nooks and crannies. Everything from toothpicks, old tooth brushes, picks, you name it. Just remember, more soaking = less scrubbing.
As for the wood, i would think just applying heat and "turning it to liquid" would make it penetrate deeper. You mentioned soaking in mineral spirits. Don't soak in anything! Especialy if its a laminated stock like some of the late ww11 mausers. The best thing I've used for cosmoline soaked milsurp stocks is easy off oven cleaner. Dampen the stock with hot water. Stand the stock straight up and down, spray it down with the oven cleaner untill you used enough, then spray it on some more. Let it work for a little while, maybe 10 minutes, give or take depending on how bad the stock is. Wipe down with a ooo steel wool and rinse with a good sharp spray of hot water. You might have to do this several times, but it will get the grease out. I've done this on mausers, p-17, springfields, carbines, garands, you name it. It's some work, but worth it in he end. Let it dry good, maybe go over with fine steel wool, then refinish with the finish o your choice- tung oil, linseed, truoil, lin-speed or whatever.
By the way, what did you pick up?
The Second Ammendment...
