This may sound crazy but the best and easiest method I've ever used....Wait till your wife is not around, and run it through the dishwasher on the High Temp water setting. My M1 carbine stocks came out clean as whistle, and with their cartouches intact.
Have done this many times with AMAZING results.
But, regarding your stock, the CMP site states that the wood may not match. Judging by your pictures, you have either two types of wood, or two types of finish. Your choices are:
1) Live with it. After all it is a service grade rifle.
2) Strip all of the wood and hope it's similar enough to looks the same upon refinishing.
3) Buy a new stock set with matching wood.
Good luck,
