Most mold growth on car exteriors is caused by the accumulation of moisture, which can be due to leaks or poor weather conditions. This growth can spread out, damaging the paint, making it important to start removing it as soon as you spot it.

Once you have all your equipment ready, it’s time to prepare a cleaning solution. While there are several ways to make a cleaning solution, you can combine bleach and water to make a solution.

  • Combine ten parts of water to one part of bleach.
  • Mix the solution and ensure that it’s diluted correctly.
  • Pour it into the sprayer and shake to mix the solution.

Begin the Cleaning Process

Now that everything is set up and mixed, it’s time to remove the mold from your car’s exterior.

  • Allow the solution to sit on the car’s surface for 5-10 minutes.
  • Use a microfiber cloth to wipe the surface of the car.
  • Hose the car down with clean water to rinse the car.

Dealing with Stubborn Mold

While the soap solution should work, dealing with stubborn mold requires a bit more effort. Here’s what you can do:

  • Use a cloth or rag to apply some undiluted vinegar on the mold.
  • Allow it to sit for half an hour.
  • Scrub the mold with a scrub pad until it comes off.
  • Rinse the car with water.

Preventing Future Mold Growth

Finally, as important as it is to remove the mold from your car’s exterior, it’s equally important to prevent it from happening again.

• Dry off the car when it’s wet.

• Park in covered areas when possible.
