I had to hang up my skates for the summer, and I am always looking for ways to prevent blade rust over the humid off-season. I recently bought a hand-tool from a well-respected manufacturer and they recommend Camellia Oil as a mild, non-toxic rust inhibitor for their tools.
I had never heard of it before, and a search told me that it's a vegetable oil often used in cooking in Asia. Can't get any more non-toxic than that!
I bought a spray bottle of it from the tool manufacturer (

I'm wondered if anyone else has tried this as a rust preventative? If the claims are true (and I have no reason to doubt the tool manufacturer), then I'm switching over to it to avoid the smelly hardware-store oils that I've been using.
