Step #1. Get rid of surface mold

To remove any visible mold, it is highly recommended to use a power washer. The water pressure from a standard garden hose is simply insufficient.

You can always go to your local vehicle wash if you don’t have access to a power washer. A high-powered water hose like this is commonly found in self-service wash booths.

In using the power washer, you can begin at the roof of the vehicle. Through this, you can figure out how much pressure is necessary during the rest of the mold removal process. You can also start at the top as this will cause the mold to drop back down the bottom.

However, if using a high-powered pressure washer does not do its job, especially if mold has been sitting on your car paint and has been baked on it for too long, you can try other alternatives.


Try an all-purpose cleaner

This cleaning agent is effective on dashboards, upholstery, and many other types of surfaces. All-purpose cleaners are known to do the cleaning trick as they do not contain any harsh chemicals that might potentially damage your car paint. 


Try a heavy-duty car wash soap

For bugs, tar, and other contaminants that are difficult to remove, you can opt to use a heavy-duty car wash soap. As such, you can use it in dealing with molds in your car’s exterior.

However, for this car wash soap to be effective, try doing a pre-wash. Through this, it will be easier to remove the mold.

Also, you can save your energy for something else instead of exerting all of it in additional scrubbing. This cleaning solution is recommended to be used with a foam cannon because you can coat the car with snow to loosen up the mold before scrubbing. 


Try vinegar

Some mold may remain on the vehicle after it has been power washed. If this is the case, apply a solution of vinegar and water. 8 parts vinegar to 2 parts water is the dilution ratio.

This solution can be mixed in a bucket or sprayed using a spray bottle. Coating the car with the spray bottle will be considerably easier.

You have the option of spraying the entire car at once or concentrating on certain portions at a time. If the mold has been smudged on the car for a long time, wipe it with vinegar and let it sit for a while. After a few minutes, stir the mold with a clean microfiber cloth and wash it away.


Step #2. Apply a paint correction

Once you have chosen what cleaning agents fit best in your mold remediation process, you can now proceed into applying a paint correction. If the mold has been caked on the exterior for years, it is crucial to do the following procedures.
