The best moisture absorber for cars.

Whether it’s from a humid climate, condensation, or spills, the air in your car is likely to have some degree of moisture which can cause mold and nasty odors. The best way to reduce moisture in your car is with a good car dehumidifier or moisture absorber. Besides improving the air quality of your car, the best car dehumidifiers also remove condensation on windows during winter. Easy-to-use, highly affordable, and reusable, these small, portable car humidity absorbers make driving in any weather a breeze.

Should I use a moisture absorber or dehumidifier?

Most people use the terms dehumidifier and moisture absorber interchangeably, but there’s a slight difference. Moisture absorbers, also known as damp traps, are cheap solutions for trapping excess moisture. They use absorbent materials such as silica gel, bamboo charcoal, or calcium chloride to absorb moisture from the air. Some, like the charcoal-based pouch absorber, are often combined with an air freshener. So, moisture absorbers for cars can help with light moisture issues.

However, you want a dehumidifier if your car has been exposed to a highly damp environment. In such cases, you want to be sure that all the moisture has been absorbed so you don’t get stuck with a build-up of mold and mildew. These handy gadgets come various in all kinds of capacities, types, and sizes. Some mount under the driver’s seat or rear passenger seats, some run on electricity while others are powered by rechargeable batteries.

So, if your car has AC and stays indoors most of the time, you don’t need to buy an expensive dehumidifier – a moisture absorber will do just fine.

 How to Get Rid of Mold in the Car

There are some steps that you can take to deal with mold in your car. But if the mold infestation is severe, you might want to hire a professional- it’s not always safe to clean up mold yourself for health and safety reasons.

First, remove everything from the car that can be dried in the sun. This includes seats and floor mats. Also, remove anything that may be harmed by water or was not properly stored over winter. Next, using a spray bottle, drench the surfaces with a solution of 50/50 white vinegar and water solution and let it sit for 20 minutes. Then wipe away the mold and let the car air dry until all the moisture is gone. This may take hours or days, or you can use fans, blowers, or wet vacs to speed up the process. Finally, wipe down all surfaces with a soft dry cloth to prevent streaks.

If you want to avoid another infestation of mold and mildew, you should buy reusable car dehumidifiers. Also, use the tips outlined above to avoid excess moisture in your car.

You can also use tea tree oil – a natural, chemical-free way to get rid of mold. Mix 10-20 drops of tea tree oil with water and soak the moldy surface with the solution. Leave it for ten minutes, then wipe it away
