Almost all of my razors have celluloid handles and I'm leery of putting petroleum-based oils in their pivot joints after they get wet while shaving.

I tried spray silicone, but the solvent-carrier frosted the surface of the ol' Robeson I tested it on.

I'm back to using RemOil, but as I've always found the admonition against using oils on plastic a good one, I'm not happy with it.

Anybody know of a good rust preventative designed for use with plastics.
