Care of your Sword & Armor
For shipping purposes the swords may come to you with an oil base product on it, or the blades will be lacquered. However, you need to keep a coating of oil or lacquer when the sword is not in use to prevent it from gathering rust. You may use any industrial oil like WD40 or any clear lacquer. If you wish to lacquer your blade and it arrives with an oil coat (you will know the difference) use lacquer thinner to first clean the blade and let it air dry. Test by wiping with a cotton cloth. It should be completely clean. Lacquer thinner will work far better than paint thinner, alcohol, acetone or other solvents. You may then put 4-6 coats as above. Do not use vegetable oil as it will go rancid. If your weapon is made from stainless steel you need not keep it oiled. One final note, the single most important thing when storing or displaying your sword or dagger is, if it has a leather scabbard, do not leave it in the scabbard. This goes even for stainless steel blades. It is, of course, fine to use a scabbard when carrying your weapon, but it simply should not be left in the scabbard for long periods of time as the scabbard can trap moisture against the steel. Also the chemicals involved in tanning leather can hasten corrosion if kept in contact for extended periods.
Your mail shirt or coif may come to you with a heavy coat of oil on it. The easiest way to remove this oil is by dipping it or allowing it to soak in lacquer thinner. Once the oil is removed, moisture in the air and perspiration will cause rust to form. There is really no way to avoid this. The best way to remove light rust is to put the mail piece into a sack or pillow case with fine sand and shake it vigorously until the rust is removed. You may wish to spray a clear silicone coat on the mail. This helps to slow rust down. The best thing is to do after use is clean it with sand. If you are going to store the mail for a longer period of time, the best thing is to oil it again and keep it in a dry place. The oil can be easily removed again. Your helmet or armour can be lacquered or oiled or simply keep it dry and wipe it down with a clean cotton cloth after wearing or handling it.
