Hi people, I have heard that you can use both olive oil and baby oil to protect a razor from rust, I know that a mix of alchohol and mineral oil is probably the best but I need a purchase that wont take much explaining to the wife (saving up credit for a posher razor in a few months or so), so I was hoping that one of these would be acceptable as I have them lying around the house, does anyone have any thoughts as to which would be better?
I am hoping to use it for daily protection as my bathroom can get pretty humid, also hoping that either of these wont need to be cleaned off prior to a quick strop and shave.

Cheers, Sillyfishyboy
