I am attemping to refinish a badly worn gun stock. One of the biggest problems to address is getting oil out of the wood so the new finish will take better. Oil is from over use of various gun oil over the years It is commonly around inlet areas for metal fit. Could be WD40 to something thought to be more exotic with polymers or molybdenum disulfide present. I have been using something referred to as white carbonate mixed with acetone that is suppose to draw the oil out of the wood. You mix the two together, making a paste, then let it dry on the wood (after stripping completely of course) and brush it off. It’s suppose to leach the oil from the wood. After 6 applications, it doesn’t appear to be leaching very much oil.
Any suggestions would be appreciated.
