Using this welding jacket is easy. Just put it on like a regular jacket and fasten the snaps. Make sure the flip - up Velcro collar is in the right position for extra protection. You can use the two large outside pockets to store small tools or other items safely. When you're done welding, take it off carefully. As for maintenance, you can gently clean it with a damp cloth to remove any dirt or debris. Avoid using harsh chemicals as they may damage the materials. Also, store it in a dry place to keep it in good condition.
