I have a bottle of mineral oil from cvs which I am hoping to use on my high carbon steel katana, but I read the ingredients and it says in contains 99.9% Mineral oil, but doesn't say what the other 0.1% is and I'm worried that If it is water it may defeat the purpose of oiling my sword. If some one knows more about this could help me I would appreciate it.
P.S. I wasn't sure where to post this so if it is in the wrong section please let me know. Ty
