A cleaning agent that effectively removes scale and water stains from aquariums. This is a cleaning agent recommended by Azuma Kogyo's house cleaning professionals, from the "Azmagic" series. Developed specifically for scale removal, it powerfully removes stubborn white scale-like stains on mirrors using a combination of two types of abrasive materials (large and small) and the power of the cleaning agent. By polishing with the included sponge, you can clean efficiently without using much force. In addition to mirror scale, it can also be used to remove water stains from bathroom, kitchen, and toilet fixtures.
