Oil from the seeds of Camellia oleifera (same family as Camellia and tea) is the traditional Japanese choice for protecting tools from rust: use it when cleaning, and as a regular protective coating. Leaves a lovely deep, non-oily finish, and it’s odourless and tasteless (handy for kitchen knives, but don’t try drinking it.)
Cold pressed Camellia seeds blended with white mineral oil. Not for human consumption.
