How to Remove Algae and Mould From Car

You might have noticed green stuff on the panels, seals, and plastic of an older car that you’re restoring.

Algae and mold are organisms that can grow in your shower. They’re unsightly but relatively easy to remove.

In this article, I’ll take you through a guide on how to remove algae and mold from cars.

How to Find Mould in A Car and Why Is It Dangerous?

There’s a good chance you’ve never seen the word “mold” and never tried to find mold in a car. It sounds like something from the original Star Wars movies.

The truth is that you can find mold in your car, and if it’s left there for too long, it can do serious damage.

The reason mold is dangerous is because it produces allergens that are harmful to some people who breathe them in.

Mould is also dangerous to you because it produces toxic products that can damage your liver, kidneys, and nervous system.

It’s for this reason that I strongly suggest you take action to remove mold ASAP.

But how do you find mold in a car and how do you tell if there’s mold on your vehicle? Well, it’s quite simple really. If there’s mold on your car, then the smell of the material that was affected by it will be stronger than usual.

A few examples of what that might look like are; the carpet in your car will smell swampy and musty, or there may be clammy growth on the dash and plastics.

What Causes Mold And Why Should I Get Rid Of It?

Mould needs the right combination of moisture, air, and warmth to grow.

Here are a few examples of how that happens on cars:

  • The temperature is relatively warm inside your car compared to the outside. Air conditioning and heaters make sure your car stays at a constant temperature regardless of what the weather is like outside. This is why it’s so easy to get mold in a car. Mould will grow on plastics, carpet, the dash, and even seats if moisture gets trapped inside your vehicle.
  • Condensation. Inside our vehicles, the windows repel moisture, keeping the inside of your car dry. When it’s cold outside and you’re driving for a long time, air condenses on the inside of your windows forming droplets of water. This is known as condensation. It might not seem like an issue now, but remember that moisture will attract mold in your vehicle.
  • Hot humid weather. When you drive your car, it’s exposed to the environment. So there’s a chance that the heat and humidity in the outside air will come inside your vehicle. That humidity will collect on the inside of your windows, and unless you use a window sealant, it will seep into your car through any leaky seals or panels.
  • Damaged seals and panels. Mould can be seen on seals and panels that have damaged edges or gaps around them. These are usually the parts that allow air and moisture to flow freely.

How to Remove Moulds the Natural Way

I’ve compiled a few tips for you on how to remove mold from your car the natural way. That way, you don’t have to call in expensive restoration professionals every time something goes wrong.

Here are a few straightforward steps you can take:

Using Vinegar and Water

Wash the affected area with vinegar and water mix. When mold is found on windows or seals, use a mixture of equal amounts of white vinegar and warm water to wash it off. You can then rinse the affected area with either clean water or vinegar.

Using Freshwater

Fill up your car with fresh water and leave it in the sun to naturally dry. You can even try using a hairdryer and placing it under the affected area for a while. This will naturally dry out all moisture that has been trapped inside your vehicle.

Using Ventilation Fans

Use ventilation fans to get rid of any dust and mold spores in the car, especially inside your trunk. Inspect all panels, seals, and seals for cracks or gaps that can let in air and moisture through as well as sunlight during hot weather.

Using Mild Detergent

Take a mild detergent and a bucket of water and mix it well to create some cleaning solution you can use to wipe down your vehicle. Do this regularly to make sure the mold doesn’t come back again.

Using Natural Sea Salt

Use natural sea salt to clean things like floor mats, seat covers, and carpets. This will kill all germs in the affected areas. You can even mix it with water to make a paste so that you can scrub off the mold.

How Do I Prevent Mould From Running the Interior of My Car?

The best way to prevent mold from getting under your car’s seat is to wash it regularly. The more often you wash the outside, the less likely it that mold will grow on it inside the car.

You can use various methods to do this, but a great way to prevent mold from coming back is with mold killer spray that you can find online or at your local store.

How to Maintain a Car Interior Safely?

It is important to understand that it is the interior of your car which attracts mold. The only way you can ensure that you avoid mold in your car is to prevent it from growing in the first place. The best way to do this is by regularly cleaning and maintaining it.

One great way to prevent mold from growing back into your car’s interior is by using automatic car dehumidifiers. These come in different styles and sizes and they are designed to keep the environment of your car as comfortable as possible.

These are basically ventilated drying devices with which you can increase the level of humidity in your car. Once we start filling our cars with water, we create a perfect environment for mold to grow.

The only way to avoid this is by keeping our cars dry all the time and by using a dehumidifier.


When you remove mold from your car, you should also take steps to prevent it from growing again. Make sure all the seals inside your vehicle are in good condition and free from any cracks or gaps.

In addition to that, you should also pay attention to the temperature inside your car. If it’s too hot, then cool it down by closing the windows or opening up the vents. You should also avoid driving in direct sunlight as this will cause condensation on any windows and will trap molds inside your vehicle.
