I recently purchased a vintage NATO rigging knife online. The knife was covered with cosmoline. An online search of this material stated that it could be removed with cascade and warm water. I did this and now i have some staining on the blade and what appears to be some slight pitting. Id like to remove this with some steel wool but i am hesitant as i dont want to do anymore damage. Does anyone have any idea about removing the stains? oh yeah, the cosmoline is still there in some parts, not sure if i have done the right thing.
