I am sorry to diagree but Simple Green does work quite well. I used it on the last 2 24/47's that I bought and they were heavily soaked in grease and oil. I do not soak the stocks in a bath of simple green, I brush the stuff on and let set about 20 minutes and then rinse it off using hot water and a brush as stated previously. Drying is usually done in the attic in the summer after I get the grease out. I guess it would be possible to get a stock hot enough to damage it with a hair dryer if you set the hair dryer on high and left it in one spot for a long enough period of time. I have seen stock put into drying cabinets to dry them out and those cabinets get pretty warm with two or three 100 watt light bulbs to heat them. I have also used the "whiting" mix from Brownell's made into a paste with acetone to remove oil. Once you get the worst of the grease off the exterior of the stock, then the whiting comes into play as it will get deeper into the stock because of the acetone and will draw the grease out as the acetone dries. Oil soaked deep into a stock takes a mighty long time to remove and I am not convinced that you can ever get all of it out without damaging the stock regardless of what method used.
