If you want to clean up the stock and are concerned with spousal abuse after using the dishwasher, you can just use hot water and fine steel wool, let dry, go over the shiny spots again until the oil finish is gone. WARNING, as well as removing oil finish this will remove any stain. If the stock is not walnut you can end up with a blonde finish. I did, mine was beech. If this happens, blend miniwax stain (I use mix of mahogony and walnut) with tung oil until you get the desired colour (experiment on scrap wood). Looks like a nice little rifle.
