If you've never heard of the process of walnut shell sandblasting, it is a very effective way of removing rust and corrosion from an object without disturbing the layers underneath. Walnut shells have some very special qualities which enable them to be used as an effective medium for blasting away unwanted material from any surface, while leaving the layers below intact and unharmed.
