How a Garbage Disposal Works

Your garbage disposal uses a spinning plate and a grind ring to grind food into small bits. It can’t handle large amounts of food, grease, fibrous foods, trash, or bones.

Running water is essential because it helps to prevent clogs and ensure that everything goes down the drain properly. Additionally, running water helps to lubricate the garbage disposal.

What You Can Put in a Garbage Disposal

Soft Foods

In general, any food that is soft enough for you to chew is safe enough for your garbage disposal.

Citrus Peels

From time to time, try grinding citrus peels in your garbage disposal. Besides freshening the scent of the disposal, the peels help to break down any buildup.

Cold Water

Cold water should always be run when you use your garbage disposal to prevent fats from melting and sticking to the sides of the pipes.

Dish Soap

Dish soap is an effective tool for breaking up light residue on dishes and in your pipes.

Ice Cubes
