Most every home has a plumbing system that includes a number of drains. One of those drains may have a garbage disposable attached to it. It’s tempting to put all manner of things down it—and other drains, too—because it’s just so convenient. But hold on. Every drain in that system, especially the one attached to the garbage disposal, is vulnerable to breakdowns. Plumbing repairs are not cheap.
In fact, the National Average Price to unclog a drain, as I write, has shot up to $225. To make sure you won’t be calling a plumber anytime soon, do not put the following 11 items down your garbage disposal or any other household drain, for that matter.
Grease & Cooking Oils
It’s tempting, that’s for sure. Especially if it’s just that last bit of cooking oil. Or to drop that last bit of bacon or chicken skin down the garbage disposal.
It does seem reasonable that once ground up, it will flow easily through the pipes, but don’t believe it.
Grease will slowly accumulate and not only stop the disposal from grinding up food particles—it will create drain clogs the likes of which you do not want to experience. Grease and fat clings to the inside walls of pipes and that attracts other stuff to attach as well.
Never put grease, oil, or fat from gravy, meat, bacon, or poultry down any drain, even if it has a garbage disposal attached. Instead dispose of grease, fat, and oil in the trash.
Potato peels, when put down a drain, expand and attache themselves to the drain and pipes. They turn into glue.
As time goes on, that gluey starch hardens and slowly blocks the drain. This applies to garbage disposals as well.
By the time the drain stops draining, you’ll have a full-blown blockage requiring an emergency call to a professional.
Plan on this happening right in the middle of your big Thanksgiving celebration or other meal that features your famous mashed potatoes. Do yourself a favor and put potato peels into the garbage can or compost pile—never down the disposal!
Artichoke Parts, Anything Fibrous
Don’t attempt to grind anything that’s tough and fibrous like an artichoke’s leaves, stalk, or even that furry center inedible part.
Fibers from artichokes—corn husks, celery, onion skins, too—can tangle and jam the garbage disposal motor and block drains.
And by the way, citrus peels, while touted by many as a great way to freshen and clean a garbage disposal—they are a problem just waiting to happen. Trust me on that.
From personal experience, let me say that garbage disposals are, for some reason, most likely to misbehave in the presence of lime.
Fruit Pits, Seeds
Many homeowners assume it’s okay to let the pits of peaches, cherries, avocados, and other fruits go into the garbage disposal. However, fruit pits can easily crack, dent, or break your disposal’s blades.
Don’t put peach pits, pumpkin seeds, avocado pits, sunflower seeds down the drain. Your garbage disposal really can’t stand up to these hard items. A busted garbage disposal is bad enough without adding a clogged drain to the mess.Toss fruit pits and seeds into the compost or the garbage.
This is controversial as there are sources out there that insist grinding chicken bones in a garbage disposal will sharpen the blades and keep the appliance tuned-up.
I don’t know what machine they’re talking about, but this does not work for me. My advice: Don’t.
Even though very small bones will probably pass through without a problem, it’s safest to keep all bones out of your garbage disposal. These hard items can break your disposal or clog up your plumbing. Even if they are ground up, they can end up in the bottom of some pipes, causing a potential blockage. Ka-ching.
Like bones and pits, seafood shells should not be pitched down the disposal.
Whether it’s clams, oysters, mussels, or lobsters, the hard casings can damage the blades or cause a clog.
Let’s call this one debatable, then err on the side of good sense. No coffee grounds down the drain or through the garbage disposal.
While most garbage disposals can easily handle the grounds, the pipes on the other end of that handy appliance, cannot. Coffee grounds attract grease. The resulting build-up creates a gross sludge-like mess, which can then clog up a drain making it, on top of everything else, stink!
There are lots of uses for coffee grounds to give them a second life instead of disposing of them.
Here’s a good rule of thumb: If it expands in the presence of water, likewise it’s going to expand when it hits water in your pipes.
Think about it: We cook pasta and rice in water until it absorbs the water and nearly doubles in size. Think of it doing that in your pipes.
The answer is clear: No pasta, no rice down the garbage disposal. Figure out how to use it up instead!
Or if all else fails, pitch it into the garbage.
It may be an urban legend that eggshells help sharpen the blades of a garbage disposal. The folks at American Home Shield contend that to be a myth:
“Garbage disposals do not have blades. They have impellers that are not sharp, but blunt. So, putting eggshells down the disposal to ‘sharpen the blades’ will not do any good.
“In fact, eggshells are not recommended for the garbage disposal as the membrane can get wrapped around the impellers and cause damage.”
And so we should add eggshells to our list of nevers.

Who among us has not been tempted to toss an expired prescription or OTC medication down the garbage disposal, or into the toilet?
We all have those old medications somewhere in our medicine cabinet. For whatever reason—it’s expired or you no longer need it—the prudent response is to dispose of medications properly.
The garbage disposal is not considered at all proper in this context. The chemicals in medications can impact the water quality near you and that’s about the last thing you want to happen.
Do the right thing: Drop it off at your nearest pharmacy so they can dispose of it with other medical waste.
Whether oil-based, water-based, stain, lacquer, tempera or any other kind of paint—no. Do not throw the excess down the drain. It sticks to the pipes’ sidewalls, and immediately beings to impede foods from getting through. You will long regret having done this!
Instead, inquire with your city or county’s hazardous waste facility that disposes of paints properly ad in a way that is not hazardous to the earth or its inhabitants.
Don’t know how to find that facility? Ask the people at the store where you bought the paint. Or any such store near you.
