Cleaning a Japanse Sword

By Twillie2 ( January 10, 2017 at 4:15 am) · Filed under History forum

I have a Japanese sword that had cosmoline applied to the blade. I understand the cosmoline has been on the blade for almost 40 years. What’s the best way to clean the blade? And will the cosmoline damage the blade? Thanks much. R/ Twillie2
