Things You'll Need
Instructions
Remove factory oil or grease from the newly purchased sword with lacquer thinner. In the case of used swords, skip this step.
Cover blade and metal parts of your sword with sword oil or wax. Wipe with gun/reel cloth. This prevents rust and corrosion of the carbon steel sword blade by removing dust that could trap oxygen within the surface.
Treat wooden handles with wax or a specialty wood oil like lemon or tung oil. Coating the handles helps prevent the wood from getting dry and cracking. It also keeps moisture out.
Apply micro-crystalline wax or a specialty leather paste wax to your sword's leather accessories. Also use this wax on leather scabbards, sheaths, belts and even the handle covering of the sword.
Waterproof the scabbard, if so desired, with neatsfoot or mink oil. Apply as directed on appropriate surface.
