A garbage disposal is one of the handiest tools in your kitchen, making cleanup quick and easy. However, to keep it running efficiently, it’s essential to use it correctly. Misusing your disposal can lead to expensive repairs, unpleasant smells, and even plumbing backups. At Castlewood Plumbing, we know how vital a properly functioning garbage disposal is to keeping your kitchen running smoothly. That’s why we’ve put together a list of do’s and don’ts to help you maintain this helpful appliance.

Do Run Water While Using Your Disposal

Always run cold water while using your garbage disposal. The water helps flush food particles down the drain and prevents them from building up in the disposal or pipes. Cold water is particularly important because it keeps grease and fats in solid form, making it easier for the disposal to grind and wash them away.

Don’t Put Grease or Oil Down the Disposal

One of the biggest mistakes people make is dumping grease, oil, or fat into their disposal. These substances may go down the drain easily when heated, but they solidify as they cool, leading to clogs in the pipes. To avoid this, pour grease and oil into a container, allow it to cool, and then dispose of it in the trash.

Do Cut Large Pieces of Food Into Smaller Chunks

Your garbage disposal is powerful, but it’s not indestructible. Large pieces of food can jam the blades or overload the motor. To keep things running smoothly, break food into smaller pieces before placing it in the disposal.

Don’t Put Fibrous Foods in the Disposal

Fibrous foods like celery, corn husks, or potato peels might seem harmless, but their stringy texture can wrap around the disposal blades and cause jams. It’s better to toss these items in the trash or compost bin to prevent issues.

Do Clean Your Disposal Regularly

Harsh cleaning chemicals like bleach or drain cleaners can damage your garbage disposal’s components. Stick with natural cleaning solutions, like baking soda and vinegar, to deodorize and clean safely without harming the appliance.
