How to Remove Fish Smell From a Car: 5 Simple Steps

Quick answer: Remove the fish or contaminated material first, blot any liquid, clean the affected carpet or upholstery, neutralize residual odor, and dry the area completely. If there's no known fish spill, investigate the HVAC or another vehicle-related source.

Fish smell in a car usually comes from spilled fish, seafood, shrimp, bait, or liquid that has soaked into carpet or upholstery. Start by finding and removing the source, then clean the affected material and neutralize the odor rather than trying to cover it with an air freshener.

If there hasn't been any fish or seafood in the vehicle, don't assume the interior just needs cleaning. A fishy smell can sometimes come from moisture, HVAC problems, overheating electrical components, or other vehicle issues.

Step-by-Step Guide to Get Rid of Fish Smell in Car

Find and Remove the Source

The first step in eliminating odors of fish is to identify their source. 

• Inspect your car’s interior for any spilled fish fluids, lingering moisture, or forgotten fishing gear. 
• Check under the seats, inside storage compartments, and on upholstery for any signs of contamination that could contribute to the dead fish smell in car interiors.

Spot Clean Affected Areas

For areas stained by fish fluids, use a pH-balanced car shampoo for better cleaning results. 

• Gently blot the area with a microfiber cloth, working from the edges toward the center to prevent the stain from spreading. 
• Avoid scrubbing as it can damage the fabric or push the stain deeper.

Deep Clean Carpets and Upholstery

• Vacuum the carpets, seats, and other fabric surfaces thoroughly to remove any hidden debris. 
• For stubborn stains, use a carpet and upholstery cleaner that is safe for your car’s interior materials.
• If you notice discoloration, repeat the cleaning process until the stain fades.

Neutralize Odors with Natural Deodorizers

Baking soda is an excellent natural deodorizer. 

• Sprinkle a generous amount on the stained areas or where the smell is most prominent.
• Let it sit for several hours or overnight, then vacuum it up. For additional odor neutralization, place a shallow bowl of white vinegar in the car overnight to absorb lingering smells.

Ventilate and Dry the Interior

• Open all doors and windows to allow fresh air to flow through your car. 
• Turn on the air conditioning and set it to circulate air for a few minutes. 

This helps to remove any lingering odor from the interior and ventilation system, ensuring the fish smell in the car is fully addressed.

Why Does My Car Smell Like Fish

A fishy smell in a car usually comes from spilled seafood, bait, or liquid soaked into carpet or upholstery. If no fish has been inside the vehicle, the odor may instead come from trapped moisture, the HVAC system, hidden organic material, or, in some cases, an overheating vehicle component.

If the smell resembles hot plastic, appears suddenly, or becomes stronger when electrical or HVAC components are running, have the vehicle inspected instead of treating it only as an interior odor problem.

Home Remedies to Eliminate Fish Smell in Car

Baking Soda as a Natural Deodorizer

Sprinkle baking soda generously over carpets and seats, letting it sit for several hours. This method helps neutralize odors and leaves the interior fresher after vacuuming.

White Vinegar for Stubborn Smells

Place a bowl of white vinegar inside the car overnight to absorb odors. Vinegar effectively neutralizes strong smells without leaving a lasting scent.

Don't Rely on Air Fresheners to Remove the Odor

Air fresheners and essential oils can make the cabin smell better temporarily, but they don't remove the source of a fish odor. Use fragrance only after the contaminated area has been cleaned and fully dried.

Can You Get Fish Smell Out of a Car Overnight?

You can often reduce a fish smell significantly overnight if the spill is caught quickly. Remove the source, clean the affected carpet or upholstery, absorb as much moisture as possible, and leave the interior ventilated until completely dry. Baking soda can help absorb some residual odor on compatible dry fabrics, but it won't replace cleaning the contaminated material. If fish liquid has soaked into carpet padding or seat foam, one night may not be enough and deeper extraction may be necessary.

When to Contact Professional Detailers

If the fish smell in car interiors persists despite thorough cleaning of the interior or stains being deeply embedded in the upholstery, professional detailing services may be necessary. Professionals use specialized equipment to target hard-to-reach areas and remove stubborn stains.

Auto detailing experts utilize advanced cleaning techniques to remove fishy smells from cars. Professional tools and products ensure that all traces of odor and stains are removed effectively.

Severe odors that remain after the contaminated material has been removed may require professional odor treatment.
