Instructions
Create a mixture of one part vinegar to two parts neatsfoot oil or linseed oil. Rub this mixture over the leather with a soft cloth.
Allow the oil and vinegar mixture to soak into the arm guards overnight.
Buff the leather with a clean, dry cloth to remove excess oil and polish the guards.
Rub a leather conditioning cream into the leather with a clean, soft cloth. This will protect the leather from moisture, such as sweat, rain and dew.
Repeat the cleaning process frequently. If you keep the leather clean and conditioned, the arm guards will remain useful for many years.
