Baking soda is an effective ingredient that can help remove the smell from a flooded car. You can sprinkle it over the carpet for some time, and it will remove all the pungent smell and will give out a fresh feeling. Another advantage of baking soda is its ability to absorb moisture from the surroundings. This also helps in drying out the carpets to a great extent. However, the application should be followed after a thorough clean-up to prevent underlying moisture.
