I think it's relatively clean. EBM (Ebamatsu Shoji) Aluminum Pro Chef Cylindrical Pot 27cm (with markings) (φ270xH270mm) 15 liters Gas only The EBM Aluminum Pro Chef series offers a sure feel for professionals. Its feature is the solid, generous plate thickness. It has the rigidity to withstand harsh commercial use, and because heat is evenly distributed without unevenness, it is difficult to burn and is suitable for long cooking times. This is an entry-level model for commercial use that delivers authentic specifications at a reasonable price. Aluminum has excellent thermal conductivity (about 13 times that of stainless steel), so the entire pot is heated slowly. There is little temperature difference inside, making it suitable for making soup. The thicker the plate, the more the heat is dispersed, making it less likely to burn.
