If you are worried about oil smell try this: Give it a good cleaning, then use brake cleaner to get rid of all the solvent or oil present. It will evaporate completely, leaving nothing but dry metal. Then lubricate those parts that need a little with a spray on dry lubricant. Remington makes a good one called Dri-Lube. It dont have hardly any smell at all. If you are going to hunt in wet conditions, use Johnson' s paste wax on the exposed metal areas. Once you buff it out it dont smell neither. I have used those methods a lot because I hunt in a very humid climate. Finally I just got smart and bought a stainless/synthetic rifle and quit worrying about it.
