To ensure the longevity of the RFB polyurethane foam chest protector, it should be regularly cleaned with a damp cloth and mild soapy water. After cleaning, it is important to allow the material to air dry and to avoid direct heat sources or prolonged exposure to sunlight during storage to prevent cracking or deformation. The chest protector should also be stored dry and at room temperature, ideally in a bag to protect it from external influences.
