When the interior and exterior of the car have different temperatures and moisture contents, condensation results. Because it was left outside in the cold, warmer air became trapped inside your automobile, giving it that moist smell. Because moisture in the automobile interacts with the chilly air on your windscreen, water droplets have formed inside the car. Many factors can lead to condensation. Remember that even if your automobiles aren’t filled with damp goods, leaving wet items inside them—like an umbrella or jacket—can lead to severe condensation.

After-effects of not dehumidifying a car

Condensation can lead to minor annoyances or serious health and safety issues.

Fogged windows reduce visibility, which is risky when driving in the winter or right after a storm. More passengers (breathing) inside the vehicle can quickly cause condensation to accumulate on the window. After de-misting your windows with the aid of your car’s fans, they will have streaky marks.

Mold is a fungus that thrives in warm, moist areas, such as those in your car. A cracked window or sunroof on a rainy day provides the perfect conditions for the growth of mould. Mold spore inhalation has the potential to cause catastrophic lung damage. The interior of your car may be particularly tough to clean of mould stains.

Moisture condensation within your car causes evaporative damage to the electrical system. The seals on the majority of electrical components can degrade over time, allowing moisture to enter. If you do this, your ECU may experience interference and electrical problems.

How to dehumidify a car

Natural moisture absorption

Use your car’s air conditioner or defroster as a dehumidifier if you don’t have an external moisture absorber. Cars include vents for evaporating moisture that help keep the pressure around the doors constant. You may speed up the dehumidification process in your car by using the blower or fan on your air conditioner (instead of your defroster).


Think of a car dehumidifier as a bag full of silica gel particles or other moisture-absorbing materials. It is rechargeable and will never leak. It lessens the likelihood of mould growth and other interior damage by preventing condensation from forming on the car’s interior windows.

Investing in a decent dehumidifier is a simple solution to this problem. Automobile dehumidifiers don’t require charging or recharging, either. A car dehumidifier is your best option if you’re experiencing early-morning window fogging, musty odours, or other moisture problems.

Moisture absorber

A moisture absorber is an excellent solution to get rid of scents in your automobile provided it hasn’t sustained serious water damage from flooding or standing water. You might notice a musty smell inside the car, misting on the windscreen, or leaks coming from the cupholders. If you live in a humid environment, regularly utilising a moisture absorber will keep things smelling good.

Moisture absorbers function by using calcium chloride crystals, which take moisture from the air. They are frequently combined with air fresheners. In essence, the crystals collect the water and then release it into a bottom chamber. A dashboard pouch absorber composed of charcoal can be used as an option to deal with moisture buildup.


If there has been any minor flooding within your home, an industrial blower, also known as a floor dryer, is ideal. The fact that they perform a terrific job of directing airflow to the ground while making a little noise allows the carpet to dry more quickly than it would with a regular fan. In the worst-case scenario, use a wet vacuum rather than turning on the blowers.

Get rid of any standing water before using a blower or other power equipment on your car. Under the carpet, there is a pull-back foam layer that can be used to absorb up as much water as possible. Moreover, you might want to take the chairs out if there is a lot of standing water.

You should think about working in a well-ventilated garage because you’ll be keeping the doors and trunk open for a long amount of time. After a pipe burst and left my carpets soaked, I used these blowers all night to dry them. All that is necessary is to be sure to rotate them frequently.

How to get rid of mold or a musty smell in your car?

Here are some solutions to assist you in getting rid of the problem quickly. 

  • Verify that there are no leaks. This type of opening could allow water to leak in, leaving moist patches. Mold can grow when there is moisture and a high humidity level. Ensure that all of your window seals are functional.
  • To assist in removing the dirt layer that retains and stores moisture on the inside and outside of the car’s windows, use a specialized glass cleaner.
  • Utilize a vacuum to completely eliminate mold. Use diluted white vinegar to wipe down the remaining spores. You might want to thoroughly wash and dry the seats and carpets, apply an interior shampoo, and purchase new floor mats for your car, depending on the extent of the infestation.
  • The interior of your automobile might benefit greatly from the inexpensive purchase of car mats. Carefully wash and dry your automobile seats. Everything must be thoroughly dry before being stored.
  • Ensure adequate ventilation in the cabin. The ability to ventilate and dry off wet areas within the automobile when the windows are open reduces the likelihood of moisture accumulation. This makes it possible for the car to vent hot air.
  • Invest in a car dehumidifier to keep mold that from returning. 


While some moisture will undoubtedly build up in your car, getting rid of it is not entirely difficult. While direct circulation is necessary for flood damage, a spilled beverage or a general musty stench may merely need a moisture absorber and some air circulation. You might not have much luck if water has gotten into your engine, so don’t turn on any electrical systems out of caution. If you are unsure about drying out your car on your own, contact a Roto-Rooter or other water removal service in your region. If the price is affordable for your budget and they commonly have these blowers, they could be able to help.
