What you'll need for light rust:
>Mineral oil (A bottle can be picked up at most pharmacies in the laxative section)
>Clean cloths/rags
>A nylon toothbrush
>Cotton swabs
What you may need for heavier rust (be very careful selecting these)
>scrub pad intended for copper bottomed pots (there are scrub pads that are more abrasive, don't use them)
>Brass wire brush (Only use this when the underlying metal can't be seen beneath the rust. Take a magnet with you when you get it so that you don't buy a brass plated brush which can fuck up the steel's remaining finish.)
DO NOT USE ABRASIVES OR ACIDS ON THIS
Your goal is to remove the red oxide on the sword without removing or damaging anything else on it. Be patient and work at it with the toothbrush, cotton swabs and rags before moving to anything more dramatic, and post pics of what it actually looks like before you start.
