These eventually slow down the disposal. They may end up clogging it necessitating a replacement. They can also dull the blades, and therefore call for replacement.

“Avoid dumping eggshells and fibrous vegetables in the garbage disposal”

Eggshells contain the membrane, which is usually slimy. They may wind up coating the grinding surface of the disposal. This reduces its efficiency as it allows the shredded particles to move past the disposal and eventually clog it. Fibrous vegetables can tie up the joints of the disposal and disable it from moving.

“Keep off bad smell”

Foul smell is a sign of decomposition. It implies the presence of bacteria. In this case the bacteria act on the food, therefore, releasing the odor. This is dangerous since bacteria action results in acid. The acid may corrode the metallic parts of the disposal. In this case, the areas responsible for grinding the waste. You can avoid this by disinfecting the garbage disposal after washing it.[

“A smelly unit”

This is a sign that there are particles trapped in the system. If the smell will not go away with frequent washing, then that’s a red flag. You need to replace such a disposal.

“Too noisy a garbage disposal”

This may be caused by a metallic object trapped in the disposal. If you remove and yet the disposal still doesn’t work, it may be a sign of malfunction.
