I would use mineral spirits and a scratch awl. Some would warn you against using steel, and perhaps that is wise, but the scratch awl I have seems to be softer stuff than hardened bearing surfaces. If you want to be cautious, use a brass brush. Whatever you use, you will also need a lot of elbow grease and patience.
