Causes of Musty Smells in Cars

Before we dive into the methods to get rid of the musty smell, it’s essential to understand the underlying causes. The musty odor in your car is often a result of moisture buildup, which creates a breeding ground for mold and mildew. This can happen due to various reasons, such as:

  • Water leaks from windows, sunroofs, or air conditioning systems.

  • Spills or forgotten wet items in the car.
  • High humidity levels in the environment.

Vacuuming the Interior

Use a high-powered vacuum cleaner with attachments to thoroughly vacuum the entire interior of your car, including seats, floor mats, carpets, and crevices.

Pay special attention to areas where moisture may accumulate, such as under the seats and in the trunk.

Use a crevice tool to reach into tight spaces and remove debris or dirt contributing to the musty smell.

Steam Cleaning

Steam cleaning is an effective method for deep cleaning and sanitizing your car’s interior, including upholstery, carpets, and hard surfaces.

Rent or purchase a steam cleaner specifically designed for automotive use.

Activated Charcoal

Similar to baking soda, activated charcoal is excellent at absorbing odors. Place a few charcoal briquettes in your car’s open container or bag.

Leave the activated charcoal in your car for a few days to allow it to absorb the musty odor.

If the musty smell is persistent and accompanied by visible signs of mold or mildew, it’s essential to address these issues directly. Follow these steps to tackle mold and mildew in your car:

Sunlight and fresh air help dry out the interior and discourage the growth of mold and mildew.

Leave your car parked in a well-ventilated area for a few hours to let it air out.
