I just received a new Yugoslavian SKS ftom J&G Sales and man is it a beauty! It is brand new, no marks of any kind it even came in a matching serial numbered box. It has a ligh coat of oil on it, it seems to thin to be cosmoline. Normally I would just use mineral spirits on it, but the wood and metal is so nice I want to make sure I don't darken the wood or stain the metal. Any advice would be appreciated. One guy suggested acetone as it dries quickly, but that seems harsh to me.
