This just occurred to me since I have started to amass a collection here. I have seen many rusty or pitted razors which means that they were in a situation at least once in their life where they were not used much. (and probably in a humid environment, like a bathroom) I know that you oil a straight razor after use before putting it away but I don't read much about the safety razor getting the same treatment. Does anyone here oil them up before putting them up on a shelf knowing that they wont be in action for a while? If so what kind of oil do you use? I was thinking about using Breakfree CLP because I have it lying around already. Being made for firearms I would think that it would be fine for razors.
