Since the 1930s, our Grandmother, Helene, had been making and using these Dish Nets in her household to clean dirty dishes. It's the only product our family uses to wash our dishes - Why? Helene's Dish Nets are constructed of nylon netting which is tough and durable on greasy, grimey pots and pans - yet gentle and conforming to glassware and cutlery! They create an excellent lather when mixed with dish soap and are very sanitary because food particles that contain bacteria and odors rinse off and pass through the holes to wash away clean, rather than getting absorbed into the material! Even after a few months, a well-used Dish Net can look good as new!
