I recently had a number of tools shipped to my home...Although they were used (some were handplanes) they were coated with a protective viscous, sticky coating...I now would like to remove the coating and clean and tune the new "old" tools..What is best way to do that...My google search produced: mineral spirits, kerosene, WD-40....My initial try with these was not good or effective..What am I missing? Let me know your thoughts and recommendations... Thanks in advance.
