The coating improves eye protection via its high degree of surface reflection. Finish : Anti-Scratch Hard coated. RST Mirrored Shields: HJC does not recommend using any chemical products on our RST mirrored shields as they will degrade the mirror finish. For cleaning, we recommend washing the shield with warm water and soft cloth only. We also recommend cleaning the shield as soon as possible after dirt and debris have accumulated. Do not let debris sit on the shield for any extended period of time. If debris has accumulated over time, it is recommended to clean the shield in several applications. This allows the debris to weaken and break up with every application. Excessive rubbing can lead to scratching as the hard debris will act as a scuffing agent.
