What Causes Condensation Inside Cars?

At Steve’s Detailing in Denver, we get quite a few customers who are frustrated with having to either keep a rag in their vehicle or use their expensive new sweater to wipe away excess moisture from their car’s windows. Many of them ask us what causes condensation inside cars. Here, we’ll provide you with the answer so that you can take steps to prevent it.

Steve’s Detailing knows that humidity can wreak havoc on interiors, leather and more. So, if you are continually plagued by a condensation issue in your car or truck, bring it to us for helpful advice and superior cleaning, inside and out. In the meantime, let’s discuss what causes condensation inside cars.

Condensation occurs when warm and humid air meets a cold surface. When someone gets into a cold car, their breath and body carrying warm moisture-rich air meet a cold windshield. This, in turn, causes the moisture from the air to collect on the glass. It can also happen if you have wet seats or clothing in the car, leftover food and wrappers, a coffee mug with remnants of yesterday’s beverage still in it, damp carpets, leaks from a sunroof or vents, wet umbrellas, floor mats, dog blankets and even coolant leaks.

Now you know what causes condensation inside cars, follow these simple steps to keep the inside of your vehicle dry:

  • Leave at least two windows slightly open on a sunny (preferably warmer) day in the winter to help circulate the airflow, but be sure to close them by nightfall to avoid dew from settling in.
  • Invest in a moisture absorber, but be sure to keep an eye on it when it needs emptying.
  • Look for signs of dampness, especially under a rear wheel well.
  • Use your air conditioning. Yes, even in winter! This will pull the moisture out of the air, keeping your AC system in tip-top shape and your car from smelling bad when you turn it on. It will also be ready for the arrival of summer.
  • Ensure your recirculating valve is off, or you won’t be doing yourself any favors. Keep that fresh air coming it.
  • Try to avoid anti-fogging products, they seem just to leave a blurry mess on windows.
  • Air your vehicle out often by opening the windows and putting the heat on at the same time while driving.
  • Park in the garage with the windows down if possible.
  • Avoid using unbreathable car covers.
  • Check for a windshield washer fluid leak.
  • Check all your door and window seals.

Condensation is not ideal for any interior because eventually the moisture will destroy and break down the fibers in the materials, causing cracks in leather or even mold, odors and possibly discoloration.
