There are many different ways that odors can develop inside of your car and they can come from a variety of sources.


Microbial contaminants (bacteria, mold, fungus) are naturally present in your vehicle. Moisture, darkness, and warmth enable odors to develop.

Some of the moisture that condenses on your evaporator remains in the dark plenum chamber. The naturally occurring microbial contaminants utilize the moisture that does not drain out of the A/C system as a food source & breeding ground.

Once your air conditioner is off, the chamber warms up to a temperature that stimulates and accelerates microbial growth.

Once your vehicle provides a home for fungi, you will experience sporadic or continuous odors emanating from your A/C system.

How Vehicle Interior Odors Develop

Vehicle interior odors are usually found to emanate from one of the following:

  • Flood/leak damage (a mildew or musty smell)
  • Beverage Spills
  • Previous cleaning operations where the interior was not allowed to completely dry
  • Vomit
  • Urine
  • Pet odors
  • Perspiration

Odor molecules from these organic sources can get trapped in the fibers of carpet or other interior fabric items, or in any tightly enclosed space.

Your vehicle’s cabin air filter collects many different smells and pollutants over time including, dust, pollen, cigarette smoke, mold spores, and other things that can cause bad odors. You don’t want to be in an enclosed area with these potentially unhealthy irritants which is why we recommend routinely changing these filters. Carpet Care Plus removes these types of odors, leaving you with a healthier environment in your vehicle.

In most cases, our cleaning agents can rid your car of the cause of odor. In the case of odors caused from mold and bacteria, the condition is only going to become worse the longer they’re allowed to grow. And these invaders pose very real health risks as potential toxins and allergens.

There are plenty of things which cause odor besides mold; everything from food spills to bodily projections. And of course there’s the very distinct chemical odor which is caused by smoking. No matter what the unwanted odor is Carpet Care Plus will help get rid of them.
