Re: Cleaning Solutions For The Gunk From Hell!
If you're trying to clean cosmo off a gun and out of a wood stock, get a gallon or two of mineral spirits aka charcoal lighter aka parts washing solvent. It's about the safest solvent you can use and it's what is used in auto shop parts cleaners. Bee-bop down to the local Home Despot, it's in the paint isle. Then, head on over to the wall paper department and grab a wall paper tray, the disposable ones are fine if you're careful.
Now you've got a way to soak an entire action (most) or an entire stock and in some cases an entire rifle. Put your parts in it, cover with mineral spirits and let them soak for a while. Cover the tray with foil or you can make a cardboard lid, just something to help control evaporation. Take a paintbrush etc. and clean your parts.
Pour the dirty spirits in another container and save them for next time. Most of the gunk will settle out and you can decant off the clean spirits. When they get too nasty, dispose with used motor oil at your local auto supply place or recyclers.
Now if you are trying to remove carbon, well, I have a top secret formula that I use for that.....
