The Five Worst Things to Put Down a Garbage Disposal, According to Plumbers

“Eggshells, often believed to be disposal-friendly, can surprise you by forming granules that stick to grease, compounding the clog issue”


Al Fagundes, Master Plumber at A. Fagundes Plumbing and Heating.

“Your garbage disposal will do a great job of grinding starches up into a sticky paste – the finer it grinds, the stickier the mess"

Starchy Foods

Roy Barnes of Service Force Plumbing

“Pouring grease down the drain may seem like a good idea when it’s a liquid, but as it cools, it will harden, causing clogging"

Grease, Oil, or Animal Fats

Chris Palmer of Raptor Rooter & Plumbing

“Avoid fibrous or stringy foods such as celery, corn husks, onion skins, and artichokes. These can tangle the blades of the garbage disposal and cause it to jam.”

Fibrous Vegetables

Jimmy Hiller of Happy Hiller

Dumping some coffee grounds may make your sink smell better, but it also creates a sludgy paste that sticks to the drains, eventually causing backups.
