Not everyone has such a luxury, but if you're lucky enough to have a garbage disposal, you're going to want to take care of it right — because getting it fixed can be quite pricey. While plenty of foods are totally okay to dump down the drain — citrus rinds, meat scraps — not everything should get dumped in your kitchen sink.
They'll just keep spinning around and around with the blades. And if you're lucky enough to get them down, they definitely won't make it down the drain pipes.
The fibrous strings tend to tangle around your disposal's blades. This same rule applies to asparagus and corn husks.
Coffee grounds are deceptive. They appear to go down easy, but really they're going to pile up and cause a sludgy, sediment-like mess in your drain and pipes.
There's a bit of argument on this one. Some people say they're totally safe for the disposal and actually help to sharpen your disposal's blades; while others believe the shells' membrane lining can stick to the sides of the disposal and wrap around the shredder, wreaking lots of havoc. Maybe skip to just be safe.
Have you ever tried to cut through a peach pit or avocado seed? Yeah, that's just not gonna happen.
Grease and oil might not even make it into the disposal. They will likely clog up your pipes instead — so frankly, just skip this altogether whether you have a disposal or not.
Spaghetti, ziti, linguine, fusilli — it always expands when exposed to water, even after you've fully cooked it. So whether you have a garbage disposal or not, you shouldn't dump it down the drain, where it'll swell and either fill the disposal trap or cause even bigger problems. Ditto for rice.
These suckers can cause a soupy mess in your disposal down the road — even if you think you can get away with dumping them down the drain from time to time. The same goes for other starchy vegetables and beans.
