Knowing how to clean stinky drains will help you keep kitchen odors under control. It’s certainly helped me! Living with two males and two (male) cats, I wind up playing “What’s That Smell?” far more often than I like.
Most of the time, I can trace the source of the stench back to one of the guys. Sometimes it’s their smelly shoes — and, sometimes, it’s them.
Other times, the source is a nasty sink drain and I can’t blame the guys about that at all.
Smelly drains are usually the result of built-up food residue. Fortunately, smelly drains are easy to clean and, if you make a habit of it, you can keep them odor-free.
How To Clean Stinky Drains
There are a variety of ways to eliminate drain odors. Many people find that a combination of methods works best, so choose the one that’s most convenient for you to start, then try another approach if the smell persists.
Pour: Often, stray hair and other debris get stuck in soap scum that’s lining the pipe and create smells. Treat that quickly by pouring a couple of quarts of very hot water down the drain. Don’t use boiling water, though — it can damage pipe fittings and joints over time. Wait for five minutes, then follow with cold water to solidify any remaining grease. Finally, repeat the hot water flush to remove that last bit of congealed stuff.
Deodorize: Heat four cups of white vinegar to until it’s just simmering. Let it cool one minute (again, because we don’t want to pour boiling stuff down the drain), then flush the drain with half of it. Rinse with cold water, then follow with the rest of the hot vinegar. This method usually powers through any small clogs, which are often the source of the smell.
Scour: Run hot tap water down the drain. Turn the water off. Dump a cup of baking soda down the drain and then chase it with two cups of hot vinegar down the drain. (Watch out, it’ll fizz.) Wait a half hour, during which the fizzing will subside and eventually stop. After the time’s up, flush the drain with hot tap water again.
How To Keep Your Garbage Disposal From Smelling
Using any of the above methods every couple of weeks will keep your drain from developing a nasty residue that can lead to small clogs.
Sometimes, though, kitchen garbage disposals need a bit of extra help. Here are two things you can do that will keep your kitchen sink smelling fresh all the time.
Run ice cubes in the disposal: Ice cubes are hard, so they scour the disposal blades while it runs. The cold temperature also helps collect any excess grease in your garbage disposal and carry it away.
Grind citrus peels: My mother shoves half a lemon down her disposal and lets it whir around until it’s gone. That clogs my sink, though, so I slice up lemon or orange peels before grinding them. It does give a pleasant smell to the sink and, thanks to the citric acid it helps remove greasy buildup. You don’t need to waste a piece of fruit on this, either — just stash lemon or orange halves in freezer after using them in recipes. Pop one straight from the freezer down the disposal and it’ll clean and deodorize at the same time.
To keep odors away, make cleaning stinky drains part of your weekly kitchen cleaning routine.

I love the ideas for cleaning bathroom sinks. We usually use drain cleaner but your methods sound so much less corrosive.
Dearest Katie,
You always offer the most practical remedies. Prove of great observation and storing wise words of wisdom to resort to in case of a problem. Have a great day.
Hugs to you,

My dad always tells me to use the ice cube down the garbage disposal method and I always laugh. Glad to see that you recommend it too!
Hi! Thanks for the great tips on eliminating that awful odor which recently invaded my kitchen sink drain. Hot water + vinegar did the trick!
Glad to hear it!
I’ve read all the suggestions when I had this problematic odor from the kitchen sink but none of them worked. On a separate note, I prevent bathroom sinks from clogging by draining them every day by filling the sink with water up to the brim and then draining it. I have not bought Liquid Plumr for a couple years since I started this ritual. I figured why not do the same with the kitchen sink? After I wash the dishes, I turn on the faucet and I run the garbage disposal unit before draining the sink of the water. When I do that, I then drain the sink of the water while the disposer is running. After the water has drained I let the water faucet run for another 15 seconds for good measure. Do this for a couple days after you wash your dishes and presto, the odor has disappeared. What the other suggestions don’t factor into the solution to this problem is gravity. You need to have gravity of the water to do the work for you when eliminating kitchen sink odors and also unclog your bathroom sinks to boot. If you don’t , you will waste money buying drainage products you really don’t need.
Use the same method as above with the addition of Ajax when you clean a disposal with ice. I’ve had very good luck with that method. A very old method used to clean a sink or disposal is to dump in half a cup or a little more of baking soda followed by about a cup of white vinegar. Once the fizzing stops run water and turn on the disposal. Run cold water for 20 seconds or so after you turn off the disposal. If you’re using this method to clean a drain leave it set in the drain until after the fizzing stops and then run in some water to clean any leftover baking soda residue. Another method that works extremely well for a disposal is to put some Dawn dish washing soap into the disposal then run hot water as you run the disposal. Run for a minute or so. Then put Dawn down the drain again and runin a little hot water. This time just leave the Dawn and hot water in the disposal. This method is extremely effective for hard to remove odors.
all great ways to mask the smell for a short while! really wanna fix? have one of “the guys” replace the tailpiece and the trap for around $12
You do realize many of us “girls” can do such things, right?
I used vinegar ,baking soda several times and it still stinks. I have a constant headache from the smell. I live in an apartment housing.no one else complains about it so they do nothing with mine. How can I solve this problem. Other then move out?
Baking soda alone doesn’t work; you need to follow it with hot vinegar. If you’ve done that and it hasn’t helped, chances are you have something stuck in the U-joint of your sink. You can find videos on YouTube about how to open that pipe and clean it.
I highly recommend Drain-FX. Heard about it on the Gary Sullivan show and bought it online on their website. It cleared my drains easily, effective and without the use of chemicals. Odour was gone soon after.
I haven’t heard of that one before. Thanks, Jack!
I ventured into drain cleaning as a result of fruit flies hanging around, even after I used a baking soda and vinegar wash on incoming fruit. After the volcanic baking soda and vinegar portion of drain cleaning my kitchen sinks, DEAD FRUIT FLIES presented their bodies laying in the now super clean sink. Only two, but my imagination immediately kicked into the possibility of an entire fruit fly city beneath the surface, that had just suffered a nuclear bomb.
Very very satisfying house cleaning!
It really is, isn’t it?

The Baking Soda and Vinegar worked a treat. The smell from the drain that took the Dishwasher waste water was proving a real problem. Tried bleach and One Shot ( Sulphuric Acid drain cleaner ) to no effect but the Soda and Vinegar treatment worked wonders. Thanks
Happy to have helped, Steve.
