Dead Bodies.
Eveyrthing else goes in the compost.
Our disposal burnt out months ago. We honestly don’t miss it. Our plumber told us the same thing about maintaining them = nightmare.
I was always told:
No coffee grounds
No fat whatsoever (animal or veg)
No bones
No banana peels/onion skins/celery
No corn cobs (not that we eat corn on the cob anyway)
For coffee grounds, we empty what we can into the kitchen trash. Put a paper towel down over the sink drain, run a little water to loosen the grounds on the sides of the basket, and let the stuck-on grounds fall into the paper towel. Wrap up and toss.
Fats always go into a glass jar. When the jar’s full, toss into trash (I have a collection of jars behind the dish drainer for this very purpose).

They are designed to capture orts (tiny scraps of food from plates) that are washed off when you rinse dishes. The orts sit in there and decay and eventually you notice that your water doesn’t drain as quickly and you macerate it by flipping a switch and running lots of water. This way, food does not accumulate in your sink trap or on the sides of your pipes, creating a concrete-like barrier that requires a very large man with ill-fitting pants to come to your house and deplete your bank account.
Wow, in-sink garbage grinders are picker than I thought!
They aren’t encouraged here; we’re supposed to compost organics or throw them out with the garbage.
They’re one of those items that manufacturers convinced consumers that they needed. Either that or the plumbing cartel came up with the scheme to drum up business. For your own home, not a big deal I guess. For rental properties, public housing, military housing, etc. it’s a gigantic maintenance headache.

And to those who advise “lots of water”: Ever heard of saving water ? And don’t you pay for your water ?
This sounds like a great frat-house prank.
Using blanks, of course. I hate when pranks end in fatalities…
Sounds steep.
If it makes you feel better…I had always read that you could put pieces of lemon down the disposal to clean your drain/make your kitchen smell nice. Shortly after the installation of my family’s new disposal, we had fish for dinner with accompanying lemon wedges. I scraped the fish leftovers into the disposal, and followed it with a lemon wedge.
The lemon wedge clogged up the whole works. My dad used a plunger on the sink. Somehow, God knows how, we ended up with the fish from the disposal on the roof. There was some pipe up there that connected to it I guess?
Anyway, be careful with the disposal, unless you want to help scrape tilapia off shingles.
No.
Or in the furnace.
