Anodes are an important component of several metal treating processes, such as anodization or electroplating. However, anodes can build up a heavy surface layer of metal oxides that prevents them from being effective. You can maintain your anodes by treating them regularly, to remove their surface oxide layer. Standard lab equipment is required for this procedure; do not attempt it without the proper facilities and equipment.
