Support BladeForums! Paid memberships don't see ads! Hi folks, I have some questions and need your expertise suggestions : I have a stonewashed blade knife. The blade's material is N690C. I carried it inside my jeans pocket. Because I sweat a lot and the weather here in Indonesia is humid , there are tiny rusty spots that shown up on the blade. How to get rid of those rusty spots? Which materials(Oils?) can be used to get rid of those rusty spots? Hope to hear from you guys soon. Thank you. Owen.
