M1 Carbine-All WWII Original?

[INLAND44]

Johnny; There was no intention to 'call you out' on the issue. I had actually skipped a page and had not read your comment on Gunscrubber.
The harsher solvents can bleach the patina out of Parkerizing by removing the old oil and linseed oil stains. They will not harm any metal parts. I feel like they are too strong to use on old guns except as a degreaser for refinishing. I used them for general gun cleaning for many years but not any more. Its definitely better IMO to take the gun apart and clean each piece with either a 'one-step' product like CLP or use a mild dry-cleaning solvent as mentioned, followed by a lube/protectant. There are also 'in-between' spray products like Amsoil MP that safely flush out most residues in assemblies like trigger housings while leaving metal protection.
