Helmets, armor, and some swords will often come coated in oil whem you recieve it in the mail. The oil helps to prevent rust and tarnishing while shipping the item. This is a good way to protect item when not in use, but you don't want to get oil all over you when you are using it.

How to clean off the oil

The best way to remove this oil is using lacquer thinner to clean it off then letting it air dry. You can then test it with a cotton cloth to see if you've gotten off all of the oil. You are now ready to use your item!

Storing your item

Since helmets, armor, and swords that are not made from stainless steel are prone to rust, it is recommend that you recoat the item if you are going to store it for any extended amount of time. A coat of WD-40 should work well.
