A fish scale rag has a surface texture like fish scales. It has a good cleaning effect as its material is polyester and nylon with small fish scale grid lines and delicate edge lines on the surface, making it less likely to leave watermarks or shed, and suitable for wiping glass products like cups, windows and coffee tables. However, it has limited water absorption capacity and is not suitable for wiping large - area water marks, being more suitable for the final pass.
