I've never tried it. Not sure if it will hurt the bluing if your gun is blued. Make sure you keep it from the finish on your gunstock.I was using acetone recently. I spilled a little on my painted garage floor dripping from the rag.. Instantly it softened the paint.I accidently stepped in it and my foot slide on the paint where the acetone was.The paint was removed by my shoe's sole. I know it will eat the finish off your gunstock. It will probably ruin a synthetic stock ? I don't know.If you dry your barrel out well and apply a light coating of oil you shouldn't have a problem without using acetone.
