Using this arm and leg protection set is straightforward. Just put it on and get ready for battle! After using it, clean the metal surface with a soft cloth. Then, apply a small amount of oil or WD - 40 to prevent rust. For the bright metal parts, give them a nice coat of car wax for added shine. Always store the set in a clean and dry place. If it gets wet, dry it thoroughly with a dry towel before putting it away. For the leather parts, spray them with wax or silicone spray every now and then. You can also use mink oil in some cases to keep the leather in good condition.
