What causes fishy smell

Have you ever noticed a fishy smell in your home or office? It can be quite unpleasant and leave your space feeling uninviting. There are several reasons why this smell may be lingering, but don’t worry, there are also ways to eliminate it.

One common reason for a fishy smell is a plumbing issue. If you have a leaky pipe or a clogged drain, it can cause stagnant water to build up and emit an odor similar to rotten fish. In this case, it’s important to address the plumbing problem as soon as possible to prevent further damage and get rid of the smell.

Another reason for the fishy smell could be spoiled food or garbage. Fish and seafood, in particular, can quickly go bad and leave behind a strong odor. Make sure to regularly check and clean your refrigerator, as well as take out the trash frequently to avoid any lingering smells.

In some cases, the fishy smell may be coming from your carpet or upholstery. If you’ve recently spilled something fishy or have pets, their dander could be causing the smell. Consider deep cleaning your carpet and upholstery, or hiring a professional to do so, to eliminate any odors trapped in the fibers.

Reasons behind the unpleasant fishy smell and how to eliminate it

A fishy smell is often associated with a variety of reasons, ranging from poor personal hygiene to certain medical conditions. Here are some of the common causes of the fishy smell and effective ways to eliminate it:

Poor personal hygiene:

  • Inadequate genital area cleaning can lead to a build-up of bacteria that can cause a fishy smell. Ensure you thoroughly clean this area daily using gentle soap and warm water.
  • Wearing dirty clothes, especially underwear, can contribute to the development of a fishy odor. Be sure to change your underwear daily and wash them using appropriate detergents.

Bacterial vaginosis:

Bacterial vaginosis (BV) is a common vaginal infection that occurs due to an imbalance of bacteria in the vagina. The imbalance can cause a fishy odor, along with other symptoms such as abnormal discharge. To eliminate the fishy smell caused by BV:

  1. Consult a healthcare professional for diagnosis and appropriate treatment.
  2. Frequently change tampons or pads during menstruation and avoid using scented products in the genital area.
  3. Avoid douching, as it can disrupt the natural balance of bacteria in the vagina.


Trichomoniasis is a sexually transmitted infection (STI) caused by a parasite. It can result in a fishy odor, along with other symptoms like itching and burning. To eliminate the fishy smell caused by trichomoniasis:

  • Seek medical attention for diagnosis and appropriate treatment.
  • Ensure your sexual partners are also tested and treated to prevent reinfection.

Poor diet:

A diet high in pungent foods like garlic and onion can contribute to a fishy body odor. To reduce the odor caused by your diet:

  • Avoid or limit the consumption of strong-smelling foods.
  • Increase your intake of fresh fruits and vegetables to help neutralize body odors.

Consult a healthcare professional:

If the fishy smell persists despite practicing good hygiene and making dietary changes, it’s important to consult a healthcare professional. They can help diagnose and treat any underlying conditions that may be causing the odor.

Possible causes of the lingering fishy odor

There are several potential reasons why you may be experiencing a persistent fishy smell in your environment. By understanding these causes, you can better identify and address the issue.

1. Spoiled food

One common cause of a fishy odor is spoiling food. When fish or other seafood products are not stored properly or discarded promptly, they can emit a strong, unpleasant smell. Check your refrigerator and pantry for any expired or rotting seafood products.

2. Bacterial growth

Another possible cause of the fishy smell is bacterial growth. Bacteria can thrive in moist environments, such as in a sink drain, garbage disposal, or kitchen sponge. Regularly clean and sanitize these areas to prevent the buildup of bacteria and the resulting odor.

3. Plumbing issues

A fishy odor in your bathroom or kitchen could be a sign of plumbing issues. A dried-out P-trap under a sink can allow sewer gas to enter your home, which can have a fishy smell. Additionally, a leaky pipe or drain can create a favorable environment for bacterial growth, leading to a fishy odor.

4. Water contamination

If your tap water smells fishy, it may be due to contamination. Certain water sources, like wells or areas with high iron or sulfur content, can cause water to have a fishy odor. Contact your local water authorities for testing and guidance.

5. Skin-related factors

Lastly, the fishy odor could be related to personal hygiene and skin care. Sweat, bacteria, and certain medical conditions can contribute to an unpleasant smell. Maintaining good hygiene practices, using appropriate soaps and cleansers, and seeking medical advice if necessary can help address this issue.

Identifying the underlying cause of the fishy smell is crucial in finding an effective solution. By considering these potential causes, you can take the necessary steps to eliminate the odor and create a fresh-smelling environment.

Solutions to neutralize and remove the fishy smell

Dealing with a fishy smell can be unpleasant, but luckily there are several solutions available to help neutralize and remove the odor. Here are some effective methods you can try:

1. Lemon or citrus

Lemon or citrus fruits have natural deodorizing properties that can help eliminate the fishy smell. Rubbing lemon or citrus juice on your hands, kitchen utensils, or countertops can help neutralize the odor. You can also simmer lemon slices in water on the stovetop to freshen the air in your kitchen.

2. Vinegar

White vinegar is another effective solution for removing fishy odors. You can soak kitchen utensils or cutting boards in a mixture of vinegar and water to eliminate the smell. Additionally, boiling vinegar on the stovetop can help remove the odor from the air. Remember to ventilate the area while using vinegar as the smell can be strong.

3. Baking soda

Baking soda is a versatile ingredient that is known for its ability to absorb odors. Sprinkling baking soda on surfaces, such as cutting boards or countertops, and leaving it for a few minutes before rinsing can help eliminate the fishy smell.

4. Coffee grounds

Used coffee grounds can act as a natural odor absorber. Placing a bowl of coffee grounds near the source of the fishy smell can help neutralize the odor. Coffee grounds can also be used to scrub your hands to remove the smell after handling fish.

5. Air purifiers

An air purifier with a HEPA filter can be beneficial in removing fishy odors from the air. The filter traps airborne particles that carry the odor, helping to freshen the air in your home. Make sure to follow the manufacturer’s instructions on how to properly operate and maintain the air purifier.

6. Proper ventilation

Ensuring proper ventilation in your kitchen is essential for minimizing fishy odors. Use stove exhaust fans or open windows to allow fresh air to circulate, helping to remove the smell. If possible, avoid cooking fish indoors and opt for outdoor grilling or cooking techniques that produce less lingering odor.

7. Dish soap and hot water

When dealing with fishy-smelling dishes or utensils, using dish soap and hot water can help remove the odor. Scrubbing the items thoroughly with soap and hot water can eliminate the fishy smell effectively.

Remember, prevention is always better than trying to remove the smell. Properly storing fish, cleaning all utensils and surfaces after use, and maintaining good kitchen hygiene practices can help prevent the fishy smell from becoming a problem in the first place.
