9 Things You Should Never Put Down Your Kitchen Drain

We all know paper towels are super absorbent, which is great if you're cleaning up a mess, but that same absorbency means they'll expand in your drain and clog it up. Not so great.

Stickers are, well, sticky, which means that they'll stick to your bananas, your avocados, and your drain if you let them get there. And if they don't, they can get flushed out into the ocean.

Pasta might be bae to you, but it definitely isn't to your drain. The semolina in  pasta expands when it touches water, so if you dump it in your sink it'll start to clog up your pipes. Basically, the only place pasta belongs is in your belly. 

All these fatty substances stick to the inside of sewer pipes, so you may want to scrape them into the trash rather than sacrifice your sink. Don't forget,salad dressings and mayo are also basically oils, so watch out for those too. 

 It might seem easy to just dump leftover meds down the drain, but many studies have shown that water plants can't exactly filter out all the ibuprofen you're not taking, which means if you're dumping them they're likely to end up in natural waterways. 

Coffee grounds exist because they can't make it through your coffee filter, so it's pretty obvious that they're all about clogging s**t up. Save your drain and toss them in the trash (or compost them) instead. 

Egg shells may be hella fragile, but they're really tough on the blades of your garbage disposal system. Even if they do get ground up, they create a ton of granular waste that can accumulate with other food bits and block your pipes. 

Just like rice expands when you're cooking it, it expands when it comes in contact with the water in your pipes.
