I mixed a product called "Whiting"
This stuff is flamable and do not inhale it.
I would not try this on anything other than just wood. Not sure how it reacts to the rubber grips
This is not advice, but what I have done. Are the grips checkered? I've not done this on any checkered stock. Years ago I purchased a Garand. The wood was stained and had a lot of oil in it.
I mixed a product called "Whiting" I have no idea if it is still available. But I made a paste of that and used the replacement for carbon tet. Forget what that is called now. This was described in some old gunsmithing books I had. But you need to heat the stock with a heat lamp. This way the heat allows the liquid to move into the stock. When you apply the paste put the heat lamp back on the area you are working. It rather boils the oil and grease out of the wood. When the gunk boils out it goes into the whiting so it does not soak back into the wood and that turns rather brown. Then it is scraped off.
I guess you could use a toothbrush on checkering but the risk is still there to damage the checkering.
It worked on the Garand stock, no guarantees and you are on your own. This stuff is flamable and do not inhale it.
