The Best Way to Clean and Protect a Car’s Interior

Have you ever wondered how germy a car’s interior truly is? Believe it or not, research indicates that car interiors may be as much as 2,000% dirtier than a smartphone. To put that into context, scientists previously determined that smart phones can be 10 times dirtier than most toilet seats.

If car interior statistics weren’t alarming enough, a vehicle steering wheel is reportedly:

  • Six times dirtier than a cell phone screen
  • Four times dirtier than a public toilet seat
  • Twice as dirty as public elevator buttons

Still, laboratory analysis of multiple cars revealed that the steering wheel ranks fifth on the list of the “germiest places in a vehicle.” See the order below:

  • Cup holder, front seat
  • Air vents (dashboard)
  • Floor mats (driver’s side)
  • Trunk
  • Steering wheel
  • Interior door handle (driver)

Steering wheels are not the germiest places in cars, according to research.

A car is a high-touch object requiring daily sanitizing vigilance.

Dust, dirt, grime, and food particles that collect in obvious as well as hidden places inside a car provide the ideal environment for germs and spores to proliferate. Experts report that mold can grow inside a car within 12 hours in the right conditions, and within six to 10 hours, mildew odor is noticeable.

The guidance on maintaining the safe use of high-touch objects is daily cleaning occasional deep cleaning to prevent the spread of harmful germs.


Cross-contamination of vehicle surfaces can occur airborne-to-surface, by touch, and with shoes that track and transfer dust, dirt, and other contaminates. Rubber mats are suggested over fabric mats to prevent particles from embedding into fabric floormats. Weekly vacuuming, especially between seats, is recommended for frequently-driven cars before cleaning and cleaning the interior.

Washing high-touch surfaces and objects with soap and water before cleansing is also strongly suggested. However, washing a car’s interior is challenging with soap and water. A powerful alternative is GlanHealth™ All-Purpose Surface Complete that is non-damaging to vehicle interiors.

While certain products work well together, others do not. Furthermore, some are hazardous to your health as well as the environment. A trio of efficient tools for maximum-strength vehicle interior cleaning and deodorizing includes a combination of natural UV light, quaternary ammonium compounds (QACs), and electrostatic technology. Both QACs and electrostatic technology leverage electrical polarity to spread materials evenly onto surfaces, creating a microscopic shield that neutralizes harmful germs, spores, and biofilms on contact.

Driving or riding in a thoroughly-cleaned car provides not only safety but peace of mind. GlanHealth’s Portable Protection Kit is ideal for regular vehicle interior maintenance. Included in the kit are:

All GlanHealth™ products create a nano-thin, triple layer of long-lasting germ-fighting protection. Additional benefits include:

  • Hands and body: up to four hours of sanitizing protection per application.
  • Surfaces: up to 28 days of protection per application.
  • Timesaving, easy to use: electrostatic technology, sprays, and wipes.
  • Non-damaging: safe for vehicle interiors (leather, wood, laminates, rubber, plastic, fabric).
  • Anti-static protection: safe for use on electronics and touchscreens.
