Here's What to Do If Your Sink Is Smelling

A stinky sink can make your whole kitchen or bathroom feel dirty, no matter how much you clean. For many people, the problem is that they can’t reach where the sink odors are coming from. Often, they emanate from somewhere down the drain that’s not easy to scrub.

Luckily, most smelly sinks have simple fixes. Whether it’s food debris, bacteria buildup, or something more serious, here’s how to get your sink smelling fresh again.

Why Does My Sink Stink? Common Causes of a Stinky Sink

If your sink is smelling, there could be several reasons why. Here are the most common culprits of a bad odor coming from the sink:

• Food debris and grease buildup. In kitchen sinks, tiny bits of food and grease can get stuck in the drain, leading to nasty smells as they decompose.
• Bacteria and mold growth. Moist conditions in your drain make the perfect home for bacteria and mold, both of which can cause funky odors.
• Clogged or dirty P-trap. The P-trap (the U-shaped pipe under your sink) holds water to block sewer gases. If it dries out or gets clogged with gunk, bad smells can seep into your home.
• Sewer gas leaks. If your plumbing has a crack or disconnected pipe, sewer gas could be escaping through the drain, causing a strong, unpleasant odor. This could even be a sign of a sewer backup.

How to Get Rid of a Stinky Sink: DIY Solutions

If your sink smells funky, here’s how to clean your kitchen and bathroom sink drains before calling in a pro.

1. Flush the Drain with Boiling Water

Boiling water can break up grease and wash away food particles. Slowly pour a pot of boiling water down the drain and follow with warm tap water to keep things moving.

2. Use Baking Soda and Vinegar

This natural combo works wonders for breaking down gunk and neutralizing odors.

1. Pour 1/2 cup of baking soda down the drain.
2. Follow with 1 cup of white vinegar.
3. Let it fizz for 10-15 minutes, then flush with hot water.

3. Scrub the Drain and Garbage Disposal

Use a long-handled brush or an old toothbrush to scrub around the drain opening. If you have a garbage disposal, toss in some ice cubes and citrus peels, then run it with cold water for a fresh scent.

4. Clean the P-Trap

Cleaning the P-trap is the best way to remove clogged gunk that’s stinking up your kitchen or bathroom. Here’s how to do it:

1. Place a bucket under the sink to catch any water.
2. Unscrew the P-trap, remove debris, and rinse it with warm water.
3. Reattach and check for any leaks.

5. Use an Enzyme-Based Drain Cleaner

When to Call a Plumber for Persistent Sink Odors

A plumber can perform an inspection to see what’s causing these issues. They can also recommend a drain cleaning schedule to avoid future bad odors coming from the sink.
