There are obvious drain cloggers that most of us know to avoid disposing of in the kitchen or bathroom sink, and then there are the sneakier culprits that build up slowly or dry in the pipes to cause a clogged-up mess. No matter which variety of drain clogger you succumb to, it'll result in an annoying task for you, or worse, an expensive call to a plumber.

Having worked in kitchens and as the proud new owner of a home, I've learned the hard way what not to pour down a drain.
Here are 9 common household items you should never pour down the drain and some tips on what to do if the sink water starts backing up.
9 household items that will clog your drain
Vegetable peels
Carrot, potato and other vegetable peels may fit down the drain but that's about the worst place you can put them. That organic refuse will cause backups and clogged drains faster than you can say "compost pile."
Speaking of which, a compost pile or organic waste processor is exactly where those materials should go. Here's how to start a compost pile if you're new to the game.
Oil and grease
Bacon fat shouldn't be poured down the sink, but it can be saved and used in your next recipe.

Oil and grease are two of the most common drain-clogging substances. Large amounts of cooking oil left in the skillet or a mound of leftover bacon fat from breakfast are surefire ways to build up gunk in your kitchen pipes over time.
Oil should be fully cooled and placed in a sealed receptacle before being tossed. Pork fat and bacon grease can be used to flavor your next recipe or season a cast-iron skillet.

Oil-based foods: Salad dressing, mayo, marinades, chili crisp
Try to avoid putting large amounts of mayo or salad dressing down the kitchen drain.
MemoriesThe same goes for oily foods including salad dressing, mayonnaise, marinades and more. A small spot of mayonnaise may not cause an issue, but dumping a whole bottle of past-its-prime balsamic dressing or teriyaki marinade could cause problems.
Heavily oil-based foods can't be composted and should be tossed in the garbage.
Coffee grounds
Coffee grounds can be composted but they shouldn't go in the sink.

If you make a pot of coffee every morning, disposing of the grounds is just part of the routine. Coffee grounds can be composted, but they should not go down the drain. Over time, coffee grounds will build up in the pipes and cause a backup.
If you don't have one, consider starting a compost pile to keep food scraps from ending up in the sink and garbage. Use this helpful trick to avoid that compost pile stench in your kitchen. Or add a countertop food scrap processor like the Lomi or Mill Bin if composting isn't in the cards.
Flour
Extra flour should be composted or thrown away.

If you've seen what happens to flour when it mixes with water, you know why it's not a good idea to pour it down the drain. Imagine a dense bread dough trying to make its way through your pipes. Not pretty.
If you have leftover flour from a baking project or a recipe, you should compost it or else throw it away.
Dirt and soil
Fight the urge to flush excess potting soil down the kitchen drain.

I'm admittedly guilty of this one. The kitchen sink seems like the perfect place to transfer an indoor plant from pot to pot, but soil and other dirt types can very easily clog your drain.
If you can do it without letting more than a few granules down the sink, you'll probably be OK. If heaps of potting are involved, you'd be wise to take the project outside.
Rice and pasta
Be it cooked or uncooked, rice does not belong in your pipes. Compost it instead.

Unless you have a garbage disposal, no food scraps should be going down the drain. Rice and small pasta are especially tricky since they can sneak past your drain guard and end up in pipes they shouldn't be.
To stop a starch-based clog before it happens, discard leftover grains and pasta in the compost pile or trash bin if you're not composting.
Paper products
Paper products, no matter how thin, do not go down the kitchen drain.
Angela Lang/CNET
There are no paper products that should go down the drain, even those made from thin compostable. Certain kitchen products like plates, bowls and napkins can be composted, but check carefully before adding them to your kitchen pile or smart kitchen bin. Otherwise, they should be tossed.
Paint
Oil-based paint is about the worst thing you could pour down the kitchen sink. Try mixing it with kitty litter until it dries before disposing of it.I've been guilty of this one, too but it's time to break the habit. Because paint is liquid, it might seem like a candidate for the kitchen sink but it's not. Paint adheres to pipes and if it dries, it becomes a serious plumbing problem.
One genius hack for disposing of old paint: kitty litter. Mix some litter with the old paint can until it turns solid and toss it in the garbage. Check with your local sanitation service for certified disposal facilities for oil-based paints.
How to unclog a drain with household items
Is there anything baking soda and vinegar can't do?
Angela Lang/CNET
If your drain does clog, try a combination of vinegar, baking soda and boiling water water. There are many reports from LifeProTips and Lifehacks Reddit threads of this quick fix saving homeowners in a pinch.
There are also chemical drain cleaners to help get things moving -- although a plumber we spoke to told us why you should be cautious with chemical drain cleaners. To stop food and solids from getting into the kitchen drain, a $10 sink strainer will save you grief later on.
Most important is knowing which foods and household materials to keep out of the kitchen sink and avoid a clogged pipe catastrophe in the first place.
