When it comes to bathrooms, most people try hard to keep theirs clean. But sometimes, no matter how much you scrub, there’s just that one lingering smell: the bathroom sink. If you’re struggling with a smelly bathroom sink, don’t worry—we’ve got you covered. Here are a few simple tips on how to get rid of bathroom sink smell.
Why does my bathroom sink smell inside the sink drain?
It’s a frustrating problem to have cleaned the bathroom, scrubbed the toilet, and removed the trash, yet still find a remaining odor. If this happens to you, it very well could be smelly drains, one of which could be your sink. There are a few different causes of this odor:
A very common cause of a smelly bathroom sink is poor drainage. When the pipe has a clog because of soap scum build-up or any other reason that water can’t drain, water can pool and stand. This standing water is the perfect breeding ground for bacteria, which can then lead to that unpleasant drain odor.
A Dry P-Trap
This is another common problem, and it can cause a nasty sewer smell. The plumbing trap or p-trap is a u-shaped portion of pipe beneath the sink, and it is supposed to hold a little water at all times. This prevents sewer gas from traveling up the pipe and into the bathroom.
Therefore, if the water in the p-trap dries up enough, then those foul odors can seep through the bathroom sink.
Mold or Mildew
Drain smells can also permeate your bathroom if mold or mildew is growing in the pipe. This happens due to moisture, hair, soap scum, and toothpaste that coats the pipe walls over time. It leaves that signature musty smell that mold provides.
How do I get rid of a smelly bathroom sink?
Luckily, there are a few simple things you can do to get rid of bathroom sink smell, no matter what the cause may be. Read on for our tips!
1. First, Clean the Sink’s Surfaces
When your bathroom sink drain smells bad, it’s sometimes because there is a build-up of gunk and bacteria around the sink drain. To get rid of the smell, you’ll need to clean the sink and drain thoroughly. First, clean all of the surfaces in your bathroom sink area, including the countertops, faucets, and fixtures.
If your bathroom sink is made of porcelain, you can clean it with warm water and liquid soap, bleach on white porcelain, or hydrogen peroxide on colored porcelain.
If your sink is made of a non-porcelain material, such as stainless steel or plastic, you can also clean it with a combination of vinegar, water, and baking soda.
Vinegar and water can be used for stone sinks if needed, but don’t leave the vinegar on the surface for too long. Your best bet with stone sinks is to buy a mild cleaner that is made specifically for stone.
No matter what cleaning solution you use, wipe everything down with a clean cloth or sponge afterward. You may even want to use an old toothbrush. Dig the brush’s bristles deep into the sink’s grooves, especially down around the drain where mold and mildew can grow.
Pay special attention to mold or mildew growing in or under your sink–problem areas will often be dark and damp.
You may be asking, why do you start by cleaning the sink’s surface? The answer is simple. Because sometimes the odor isn’t coming from the drain after all.
You will want to eliminate any possible smells arising from the surface of your bathroom sink before you blame it all on the drain.
2. Second, Check for Blockages and Eliminate Them
Once the sink’s surface is clean, if odors persist, then the bathroom sink drain may very well be the problem. Before anything else, you’ll want to make sure that nothing is blocking the drain. As mentioned above, types of blockage might include soap scum, hair, or any other type of debris build-up.
If there is indeed a blockage, you can try to clear it out with a plunger or a plumber’s drain snake. If it’s a fairly mild clog, you can also try pouring boiling water down the sink drain, wait five minutes, then pour down cold water to congeal any possible grease in the pipe to flush it away.
3. Third, Eliminate the Odor
Once you’ve cleared out any debris from the drain, or if there wasn’t a clog, to begin with, you can try using a commercial cleaner to get rid of any bacteria or mold. Just be sure to follow the instructions on the product label.
If you’d rather avoid commercial cleaners, try making your natural cleaner mixture with vinegar and baking soda. Simply mix a cup of white vinegar and a cup of baking soda in a bowl, then pour the mixture down the drain. Let it sit for about 30 minutes, then flush with hot water.
The bubbling solution creates carbon dioxide and water, which can break through the clog if it is small enough.
4. Finally, Keep Your Sink Smelling Fresh
If you successfully eliminate the terrible smell in your bathroom sink drain, you will surely want to find ways to help keep your bathroom smelling fresh for longer. No one wants that nasty odor to creep back in anytime soon.
One way to do this is to try using an air freshener. These can easily be bought at the store and plugged into the bathroom wall near the sink.
However, if commercial air fresheners make you wary, you can so use a natural air freshener consisting of citrus fruits or essential oils. Some great essential oils for air fresheners include lavender, cedarwood, eucalyptus, and chamomile.
To try your hand at making your air freshener, you can try simmering a pot of water with some lemon peels in it on the stovetop (or even in the slow cooker for an aroma that lasts all day). This method also works with cinnamon. It will help to fill your home with a refreshing and invigorating scent–which is much better than a sewage smell any day!
With these easy and simple tips, you should be able to get rid of that pesky bathroom sink smell for good!
