What Causes a Fishy Smell Inside the Car?

[Parker]

Reasons for a fishy smell inside the car: 1. Decaying plants or animals: Check the trunk and other hidden storage spaces for rotten bananas, spoiled apples, dead mice, etc. 2. Odor after sun exposure: Car interiors extensively use materials such as plastics, rubber, fabrics, paints, insulation materials, and adhesives. The organic solvents, additives, and other components contained in these materials (including benzene, toluene, xylene, ethylbenzene, styrene, formaldehyde, acetaldehyde, and acrolein) gradually release into the car's environment during use, which is one of the causes of unpleasant odors inside the car, especially in new cars. 3. Dirty air conditioning: After using the cold air conditioning, blow hot air for three minutes before turning off the engine to ensure the evaporation of any moisture inside.
