Military Anti Riot Control Helmet

A: Outer shell/visor: Wipe with a soft cloth and mild soapy water. Do not use organic solvents (such as alcohol or acetone), as these may corrode the material.
Inner lining/webbing: Most are removable. Hand wash in cold water and air dry. Avoid direct sunlight.
Chemical contamination: Rinse immediately with plenty of water and consult a professional depending on the nature of the chemical.

A: Natural lifespan: Typically 5-8 years. Even without use, the materials may age. Refer to the manufacturer's specifications for details.
Impact-exposed: In principle, once a helmet has suffered a substantial impact, it should be immediately discontinued and sent for inspection. Even if the exterior is undamaged, the internal cushioning structure may have failed, and the protective performance will decrease sharply.
