I've purchased several NOS Petersen Vise Grips (pre-American Tool) and plan to start using them. They have no rust but are covered in old, tacky residue. What's the best method to clean this residue and lubricate moving parts like the screw and rivets? Could you recommend specific brands of grease and oil for this? Are there additional maintenance steps I should consider, such as for the spring? Also, should I apply a protective coating to prevent rust? Thank you.
