Covid-19 and Your Car

by Larry Carley copyright March 28, 2020

COVID-19 virus
COVID-19 is a micron sized virus that attacks the lungs
and can be deadly in many people.

In these challenging times of world pandemics, social distancing and travel restrictions, you may be concerned about COVID-19 virus contaminating your car. A virus may enter your vehicle IF you have handled or touched another contaminated surface such as a gas pump filler nozzle, a door handle at a convenience store or gas station entrance, or a public restroom door or faucet handle. A virus may also enter your vehicle if someone who has the virus (knowingly or unknowingly) is inside your vehicle and sneezes or coughs, or their hands are contaminated and they touch surfaces inside or outside your car (interior or exterior door handles, radio or climate control knobs, the glove box or seat belt).

Vehicle contamination is probably NOT much of an issue for you or your family as long as nobody who rides in your vehicle has COVID-19. But it can be a real concern for UBER and LYFT drivers, and taxi drivers who transport random people in their cars.

We've seen a number of YouTube videos posted in recent weeks that describe how to clean and disinfect your car. Some are very informative and some are rather sketchy. The main points in most of these videos are (1) use a product that is EPA approved to kill the coronavirus, and (2) avoid using harsh chemicals (like bleach!) that may fade or damage interior upholstery, plastics and fabrics, and in some cases (3) buy their brand of cleaning products.

Many of the professionally produced videos do contain good advice for Germaphobes. But is all this cleaning and disinfecting really necessary? It depends.


If someone who has COVID-19 enters your vehicle and leaves their germs or grubby fingerprints in your car, there may be a risk of exposure for you or future passengers. However, the COVID-19 virus does NOT survive long outside the human body. So unless you touch a contaminated surface within minutes or a few hours at most after it was contaminated, and then almost immediately touch your nose, eyes, mouth or ears with dirty fingers, the chance of contracting COVID-19 via this type of transmission is extremely low. The greater risk of exposure and catching COVID-19 is breathing the same air as a passenger who has COVID-19 in the small confined space inside your vehicle.

If you do not have COVID-19, and you are the only person who drives your vehicle, don't worry. There is ZERO risk of exposure in your vehicle. Ditto if your vehicle is only used to transport yourself and your family members as long as none of your passengers have COVID-19 or have been exposed to someone else who might be sick or a carrier of the disease. There is no need to wear gloves, a face mask or respirator when driving your car. Save the gloves and face mask or respirator for visits to high traffic stores or locations where a lot of people are coming and going.


COVID-19, like any other virus, needs a dark moist environment (like that inside a human body) to survive and remain viable. Lab tests have shown that is does NOT survive long outside a human being. Various studies have shown that most contagious viruses die within in minutes outside the body, although some may persist for several hours. Some lab reports have shown that COVID-19 may (and we emphasize the word "may") survive as long as 1 to 3 days on some hard plastic or metal surfaces. This would include car door handles, steering wheels, dash buttons, turn signal levers, gear shift handles, even seat belts and cup holders. The question is even if the virus can survive that long on some surfaces, is there enough virus left to actually infect somebody? That's something no one has been able to prove one way or the other (yet).

The important point to keep in mind is most viruses don't survive long outside the human body, only minutes to a few hours. Some airborne virus particles can persist for several hours IF they are in tiny droplets of moisture (a sneeze, for example). Thus, airborne transmission is a far greater risk than contact transmission of the virus. You need to be really close to someone who has the virus to catch it (within 6 feet of someone for 10 minutes or longer). Or, you have to be inside a room or confined area where air circulation is limited and everyone is breathing the same air (such as inside an airplane, train, bus, car, school room, meeting room, social gathering or family gathering indoors, etc.).

Direct sunlight kills viruses in minutes. Even the toughest viruses won't survive for more than 30 to 45 minutes in sunlight. Ultraviolet light C (UVC spectrum) kills the bugs. Sunlight is nature's way of disinfecting the great outdoors.


So rather than spend a lot of time cleaning and disinfecting your car with chemical products that may be toxic or might damage interior fabrics, just park your vehicle outside for an hour in direct sunlight. Let nature disinfect it for you.


Or, just park your car for 2 to 3 days. Any virus that may have been present in your vehicle will have died the next time you need to drive your car. And we are all supposed to be avoiding unnecessary travel, right?

Viruses may be on ANY surface inside your vehicle that has been touched.


If you suspect someone with COVID-19 may have been in your car, or that you may have come into contact with a contaminated surface somewhere, and you can't just park your vehicle to allow any COVID-19 virus to expire on its own, here are the surfaces you should disinfect with a suitable chemical or wipe:

Interior and exterior door handles (front and back)

Power window buttons (front and back)

Power lock buttons

Steering wheel (the rim and all control buttons)

Turn signal stalk

Gear shift handle

All control buttons on the radio and climate control system

Power seat buttons

Seat belts and clasps

Seat surfaces

Cup holders and center console

Glove box (if recently opened)

Your keys or key fob

clean key fob
If you came into contact with COVID-19 before you got into your car, your key fob may also be contaminated. Be sure to clean it too!

Also clean your smart phone if it was used during your most recent trip

Power mirrors adjuster buttons and interior mirror (if recently adjusted)

Trunk release inside or outside (if you opened/closed the trunk or rear hatch)

Gas cap (if recently used)


Gas station pumps are one of the dirtiest objects any driver will come into contact with. Everybody who fills up touches the pump handle and buttons, and few if any service stations ever clean the pump handles or buttons. The best advice is to wear gloves or use a paper towel when touching the pump handle and buttons.

Most newer vehicles are factory-equipped with a CABIN AIR FILTER that helps clean air entering your vehicle. The filter can also clean air recirculating inside your vehicle as it recirculates through the Climate Control system. A cabin air filter can trap virus sized particles when your climate control system is set on RECIRC. It may not add a lot of protection, but it can help reduce the amount of airborne dust and virus particles that may be floating around inside your vehicle. Opening the windows to blow out stale air also helps reduce your risk of exposure.

The Cabin Air Filter is usually located behind the glovebox or in the cowl area compartment at the base of the windshield.

Stay Well!

We all need to use caution and social distancing to avoid catching the COVID-19 virus, but we don't have to become Germaphobes or live in fear of catching this pandemic disease. Use common sense, protect yourself and your passengers in situations where these is a real risk of COVID-19 contamination (planes, trains, buses, crowded confined rooms, etc.), and stay well!

To reduce the spread of COVID-19, many states are requiring people to "shelter in place" or "work from home." But we still have to go to the grocery store, and many people (like Amazon warehouse employees) still have to go to work, increasing their risk of exposure to the virus.

One way to reduce the presence of airborne COVID-19 in any indoor work environment is to install some HEPA AIR FILTER MACHINES. The primary means of COVID-19 transmission appears to be tiny aerosol particles that may circulate for up to 3 hours in indoor air. A HEPA filter is 99.97 percent efficient down to 0.3 microns which will trap many (but not all) airborne COVID-19 virus particles. The COVID-19 virus is really tiny, about 60 to 140 nanometers (0.06 to 0.14 microns). By comparison, a N95 face mask is 95 percent efficient at trapping particles down to 0.3 microns.

A good quality portable HEPA Air Filter Machine that has airflow capacity to treat a 12x16 sized room can be purchased online for less than $200. Larger more expensive commercial grade machines with higher airflow ratings are available for larger rooms. Several of these machines placed in an office, repair shop, small store or other enclosed area could significantly reduce the risk of airborne COVID-19 exposure.

Another way to fight COVID-19 that is floating around in the air or on hard surfaces is zap it with Ultraviolet light (UV). You can do this by installing several SUNLAMPS. The UV-B and UV-C wavelengths of ultraviolet light attack the DNA inside a virus, and will disable most viruses after 20 to 30 minutes of exposure depending on the intensity of the lamp. Noon day natural sunlight does the same thing. You don't want to expose the people indoors to too much UV light, so the lamps should only be turned on before work, during breaks and after work to sterilize the environment.

U.S. COVID-19 Death Toll Continues To Rise

UPDATE 4/28/2020: The U.S. Death Toll has now exceeded 53,000 and it continues to climb...
The scary part is that all of these deaths have occurred during a period of only TWO months!

To put the death toll in perspective:

Americans killed by Drunk Drivers: 10,500 per year

Americans killed in all types of Traffic Accidents: 38,000 per year

Americans who died by Suicide: 47,000 per year

Americans killed by Gun Violence/Shootings: 39,800 per year

American military killed during entire Korean War (1950-1953): 34,000

American military killed during Iraq and Asscrackastan wars: 7,500 over 18 years and still counting.

Today, the total number of Americans who have died as a result of the COVID-19 was 58,365. This is more than the total U.S. military deaths during the entire 14-year Vietnam War (1961 - 1975): 58,220

Hopefully, we will NOT exceed the number of Americans who were killed during World War Two (1941-1945): 417,000. But as this drags on, nobody knows what the ultimate total will be. Over 250,000 have already died world wide.

Update: 5/14/2020: U.S. COVID-19 Deaths Now Exceed 85,000!

The death toll continues to climb. We have now lost more Americans to a little microscopic invisible virus over the past two and a half months than those killed during the 14 year war in Vietnam, plus those killed during the past 20 years in the Middle East, plus about two-thirds of those killed during the Korean War.

And now we are rushing to "reopen" America. Really?

I realize people have to get back to work for families and businesses to survive, but at what cost? With limited testing, no vaccine and poor treatment options, it is a prescription for an even greater toll. It's like restarting an engine that has a known fuel leak: very risky and likely to blow up in our faces.

Update: 7/15/2020: U.S. COVID-19 Deaths approaching 140,000!

Obviously, we are not doing a very good job of managing the pandemic in the U.S. Early hot spot cities like New York and Chicago have cooled down, but new hot spots have arisen all across the southern states and California. Florida just set a new all-time record of 15,000 cases in one day! Meanwhile Disney World has decided to reopen in the midst of a surging outbreak. That says a lot about where we place our values as a country.

People have also turned the issue of wearing masks into a political issue. "I'm an American and the government ain't telling me to wear a mask. I got my rights." Be sure to tell that to the doctor in the ICU as they shove a ventilator tube down your throat.

Update: 8/27/2020: U.S. COVID-19 Deaths surpass 180,000 and continue to climb!

Premature reopening of bars, restaurants, schools and other places where people are in close proximity to each other are fueling the spread of COVID-19. People don't seem to realize this is a serious pandemic and people are dying as a result of ongoing community spread of the virus. We have learned more about the virus and have gotten better at treating patients who end up in the hospital. Even so, over 1,000 Americans a day are still dying from this virus. Until we have a safe and effective vaccine, and significant numbers of people have been vaccinated, this damn pandemic will continue to play havoc with our lives and economy. Be smart. Wear a mask (N95, KN95 or surgical masks are best). Social Distance (6 feet). Wash your hands. Let's get this pandemic behind us.

Update: 11/19/2020: U.S. COVID-19 Deaths blow past 250,000!

People who refuse to wear masks, social distance and take the pandemic seriously are paying a terrible price. We are now into the third wave of this pandemic. Hospitals are filling up, many cities have had to roll back rules regarding indoor dining, allowing bars, gyms and other indoor public venues to remain open. Many people have wisely cancelled their Thanksgiving plans to reduce the risk of virus spread.

In spite of all the bad news, there is also good news. Three manufacturers have announced successful vaccine trials. As soon as they are approved for emergency use, the vaccines will be made available to first responders, health care workers and older Americans. As production and distribution ramp up, the vaccines should become widely available to the general public as early as March or April 2021.

Update: April 6, 2021: U.S. Death toll from COVID-19 climbs past 550,000!

Vaccinations have been increasing every week since January 2021, with more than 40% of U.S. adults having received at least one vaccination shot to date. But the death toll hasn't declined. In fact, we are currently experiencing a 4th surge in COVID-19 cases, with more hospitalizations and deaths from the virus that refuses to go away. New variants of the virus that are more contagious and deadly continue to appear across the world and U.S., making mask wearing and social distancing more important than ever. Yet many people are behaving as if the pandemic is over. They are not wearing masks or using common sense to avoid situations that could expose them to the deadly virus. Mask wearing has been politicized as an issue of "personal freedom" not common sense. So stupid is as stupid does. The death toll will continue to climb in spite of all the efforts that are being made to end the pandemic.
