Garbage Disposal Best Practices: What Not to Put Down Your Sink


The disposal is one of the most convenient appliances in your kitchen. It makes cleaning up after meals a breeze, but it’s important to remember that not everything can go down your sink without causing potential problems and damage. Scheduling a garbage disposal service can be costly, so it’s best to follow these practices to avoid unnecessary repairs or replacements. Here are some things that should never go down your sink:

Grease and Oil

Pouring grease and oil down your sink may seem like an easy way to get rid of it, but it can cause major problems for your garbage disposal. As the grease cools, it solidifies and can clog your pipes. This applies to fatty substances like bacon grease, cooking oil, and butter. Instead of disposing of them in your sink, pour them into a container and throw them in the trash once it’s solidified.


While most garbage disposals are advertised as being able to handle bones, it’s not recommended to put any bone down your sink. They can damage the blades or get stuck in the disposal, causing it to malfunction. It’s best to throw bones in the trash or compost them.

Non-Food Items

It may seem obvious, but non-food items should never be put down your sink. This includes plastic wrappers, rubber bands, and bottle caps. These items can damage the blades or clog your pipes, leading to expensive repairs. Always make sure to double-check before rinsing off any dishes or utensils.

Coffee Grounds

Many people think that coffee grounds can be easily disposed of in the garbage disposal, but they can cause major problems. The grounds can accumulate over time, creating a thick, muddy substance that clogs your pipes. It’s best to dispose of coffee grounds in the trash or use them as compost for your garden.

Pasta and Rice

Pasta and rice may seem harmless but can cause major clogs in your pipes. When mixed with water, these foods expand and can easily get stuck in your pipes. It’s best to dispose of them in the trash or compost them.

While garbage disposals provide convenience, using them properly is important to avoid potential problems. By following these best practices, you can keep your garbage disposal running smoothly and save yourself from costly repairs in the future. Remember, when in doubt, throw it out! Don’t hesitate to call a professional if you experience any issues with your garbage disposal.
