Garbage (food waste) disposals are popular kitchen appliances. Unfortunately, many homeowners are not well informed on how to use them. It is essential that the disposal’s grinding chamber be flushed with water after each use. Decaying food particles not flushed from the grinding chamber can form acids that can eat away the die cast “pot” metal found in the case of many lower cost disposals. Some manufacturers also recommend the occasional grinding of ice cubes in the disposal.
