I'm of course always in favor of keeping it original, but I can see why you want to clean it given the butt stock. I can't tell you what to do with your own rifle, but I can tell you that as far as my knowledge goes the only way to get that off is going to be removing the finish and using some acetone (assuming that's oil or some similar substance around the butt) and a heat source. You could try just baking the thing at 180* in your oven or wrapped in tinfoil in the back of your car in the summer. I leave all my rifles as is unless I've bought them knowing they have a cracked stock in need of repair, missing parts, etc
That being said, in my honest and unprofessional opinion, what I've observed is unless your Swede is a rarer year, SA marked, officers rifle, or other things that actual collectors are after you wont hurt the value terribly. I've acquired and sold probably a dozen swedes around that condition this last year and only one appeared to have escaped a light sanding before I acquired it; none of the buyers seemed to care as they were the "collectors" of today that have an m91/30 or Turkish mauser and have scraped enough together to get a piece of the legendary M96. They arent terribly picky, nor experienced, and just want something to shoot and show friends that represents that model; if it looks pretty without being too outlandish, all the better. Just look at all the pimp shined K98's from Mitchell's that fetch what a refurbed but original Russian capture gets. With the supply being finite and dwindling, the population of people interested in milsurps growing, and your Swede being run of the mill, very lightly cleaning it up so it presents better isnt going to scare away the majority of people buying milsurps nowadays. I have yet to see an M96 on my local classifieds in any condition at under $600 last for more than a day.
I’m trying to be nice by not dissecting one of the posts above but I can’t restrain myself from saying that the advice given should be ignored.Thanks for your response. Does heating the wood release the oils? Might be better off just leaving it alone. Just a note it is SA marked
Ken:All that handling grung can be cleaned off...
