You should always be aware of whether you rifle is loaded or not. Keep all parts free of rust at all times. When you will be storing the rifle for an extended period of time, make sure it is clean before you put it away, and prevent the development of rust with a very light coat of oil. A fouled rifle will fail you during a reenactment, and is dangerous to those around you. They will be glad to help.
Neatsfoot oil is recommended.
Shoes may be soaking wet after an event, but will be fine if left to dry in shoe trees. Brass buttons, plates and insignia should be polished periodically, especially before events involving formal or ceremonial activities. More progressive units dispense with brass ornaments altogether. For this reason, any hat brass is discouraged. When drycleaning, be sure to emphasize that no crease should be put in the coat or trousers.
