Prime Plumbing, a plumbing company in Baltimore, recently posted a video on TikTok about what to never put in a garbage disposal, and many TikTokers were disappointed at what’s not allowed.

“What is one thing you should never put down your garbage disposal?” the company wrote in the text on the video.

While some of the items the plumbers mentioned arguably weren’t particularly shocking, chicken bones, for example — many TikTokers were surprised to hear a few of the plumbers say “anything,” meaning that nothing should go into the garbage disposal.

According to In The Know, disposals are generally meant for smaller foods and leftover scraps, as the bigger and tougher pieces can cause plumbing issues or dull the blade. According to Trinity Plumbing, a company in Georgia, citrus rinds, coffee grounds, cooked meat scraps, and many fruits and vegetables can go in a garbage disposal without damaging it.

With all the debris and leftovers that go into a garbage disposal, experts recommended cleaning it once a week. While you can clean a disposal by scrubbing the blades with the power source to the unit turned off, many people have embraced a popular hack on TikTok that only requires ice.
