How to Get Rid of Musty Smell in Car
A musty car smell usually comes from condensation trapped in the AC evaporator, and spraying disinfectant into the vents at the base of the windshield fixes it in most cases. A grimy cabin air filter can also recirculate mold spores, so replacing it regularly helps prevent the smell from returning. This guide covers the full fix, from DIY sprays to professional ozone treatment.
1. Clean Your Car Thoroughly The first step to getting rid of musty smell in your car is to clean it thoroughly. Start by removing any trash, food, or debris from the car. Use a vacuum cleaner to clean the carpets, mats, seats, and other surfaces. Make sure to clean the air vents, dashboard, and other hard-to-reach areas as well. Use a damp cloth to wipe down the surfaces and remove any dirt or grime. 2. Use Baking Soda Baking soda is a natural deodorizer that can help absorb and neutralize odors in your car. Sprinkle baking soda on the carpets, mats, and seats of your car and let it sit for a few hours. Afterward, vacuum up the baking soda and enjoy a fresh-smelling car. You can also place an open box of baking soda in your car overnight to absorb any lingering odors. 3. Use an Air Purifier An air purifier can help remove musty smells from your car by filtering out pollutants and other impurities from the air. There are many different types of air purifiers available on the market, ranging from small portable units to larger, more powerful models. Choose one that is designed specifically for use in cars and has a HEPA filter to effectively remove odors and allergens. 4. Use Vinegar Vinegar is another natural deodorizer that can help remove musty smells from your car. Mix equal parts of vinegar and water in a spray bottle and spray the solution on the carpets, mats, and seats of your car. Let it sit for a few minutes before wiping it away with a damp cloth. The vinegar will help neutralize any odors and leave your car smelling fresh and clean.
