1. Mold and Mildew

Sometimes a leak that has been overlooked causes a smell, and the sink will take the blame. Water escaping your pipes can soak wood and other materials around it, causing a moldy smell. That’s why, if you’re noticing a bad odor in your sink area, one of your first steps should be to look for leaks.

2. Bacteria Growth

If you’re sure there’s no leak causing the smell, the most likely culprit is bacteria. Bacteria are a natural part of your plumbing system, but when too many, or the wrong kind accumulate, they can cause terrible odors.

3. Clogged Sewer Vent

When your sink smells bad and isn’t draining properly, there’s a chance you have a clogged sewer vent. When this happens, the gases that normally get sent out of your pipes get trapped and build up, causing not only a growing odor but drainage problems too.

4. Sulfates

If your sink has a distinct rotten egg smell, you may have too much sulfate in your water. This isn’t toxic, but sulfates can damage clothing and cause digestive issues when ingested. Too many sulfates in your water can also create drainage problems, meaning the smell may be coming from both the sulfates themselves as well as a clog.

5. Plumping Errors

Sometimes you may notice a smell right after you have plumbing work done or new pipes installed. This may be due to an error made by your plumbers, such as a leaking pipe or a missing component. If you notice a bad smell coming from your sink drain soon after a plumbing visit, contact your plumber to have them double-check the work.

Hot Water and Dish Soap

If you’re really lucky, all your sink needs is a decent wash. Start by filling your sink with at least a few inches of very hot water, and then add some dish soap and agitate the mixture until it seems bubbly. When you’re ready, open the drain and let the soapy mixture run through it.

Ice, Lemon Peels, and Salt
