There are two main routes of transmission of the coronavirus that causes COVID-19: respiratory and contact. These enhanced cleaning and disinfection guidelines focus on minimizing transmission through contact, specifically on frequently touched automotive surfaces such as keys, exterior door handles, trunk latches, and vehicle interiors.
While it is not currently known with certainty how long the coronavirus survives on surfaces, a recent study published by the National Institutes of Health suggests that SARS-CoV-2 (the coronavirus that causes COVID-19) can last up to two to three days on plastic and stainless steel. Therefore, to reduce transmission, it is vitally important that all frequently touched vehicle surfaces be properly cleaned and disinfected before and between trips.
Cleaning refers to the removal of dirt and impurities, including germs, from surfaces. Cleaning alone does not kill germs, but removing germs decreases their volume and therefore the risk of spreading infection.
Disinfecting works by using chemicals, like EPA-registered disinfectants, to kill germs on surfaces. Disinfecting doesn’t necessarily clean dirty surfaces or remove germs, but killing germs remaining on a surface after cleaning further reduces the risk of spreading infection.
The CDC has published broad guidelines for cleaning and disinfecting various types of surfaces — porous, semi-porous, and non-porous — but because some of the guidelines recommend disinfectants that may discolor or damage delicate materials found in automotive interiors, Turo has compiled recommendations from the CDC, EPA, and car detailing experts on how to safely clean and disinfect vehicle interiors.
Protect yourself by wearing disposable gloves and an approved face covering, and avoid touching your face during the cleaning process.
Familiarize yourself with the porosity of common materials found in automotive interiors so that you can clean and disinfect them appropriately.
Get acquainted with frequently touched “hot spots” in a vehicle — surfaces with increased risk of contact transmission. Take special care to clean and disinfect these areas thoroughly to reduce the spread and transmission of COVID-19.
Gather the supplies recommended for proper cleaning and disinfecting.
Porous
Carpeting
Upholstery fabric
Foam and insulation
Leather
Semi-porous
Soft plastics & vinyl
Hardwood surfaces
Non-porous
Glass
Metal
Hard plastics
Vinyl flooring
Most painted surfaces
Most automotive rubber
Diluted alcohol solutions with at least 70% alcohol, or EPA-registered household disinfectants. Although the CDC recommends using diluted bleach solutions for disinfecting, these solutions can discolor and damage delicate vehicle interior materials and should be avoided for most car interiors. Please consult your manufacturer’s instructions for more details on recommended disinfectants.
Open the vehicle’s doors and windows to air out the car before you start cleaning, and leave them open during the cleaning process if you can.
Clean from top to bottom, starting with sun visors, rearview mirror, etc., moving down toward the dash, steering wheel, center console, and seats, and then down to the floor to avoid contaminating surfaces as you clean. Pay special attention to the frequently touched “hot spots”.
Clean interior non-porous and semi-porous surfaces with soap and water, being careful to avoid radios, gauges, or any electrical components — wipe those down with your multipurpose cleaner and a microfiber cloth.
Vacuum interior porous surfaces like car seats and carpet, or use car upholstery cleaner.
Spray your soap and water mixture directly onto non-porous and semi-porous materials and gently agitate with a small soft-bristled brush to create a lather, then wipe up excess lather with a microfiber towel until dry and repeat as necessary. Clean interior porous surfaces with an automotive upholstery cleaner, scrub gently and blot dry using a microfiber towel. If available, use a portable upholstery cleaner to speed up the cleaning process and remove excess moisture from the porous surfaces.
Make sure your vehicle interior is cool before applying any disinfectant. Applying disinfectant to warm or hot surfaces increases evaporation and reduces the “wet” or “dwell/contact time” of the disinfectant, reducing its ability to kill viruses.
Refer to the "contact time" or "dwell time" on the disinfectant’s instructions; the surface must stay wet for the entire dwell or contact time to kill germs effectively.
Apply the disinfectant, moving from top to bottom, according to the instruction label, paying special attention to frequently touched “hot spots”.
Clean and disinfect the key/key fob and place it on a clean surface.
Remove gloves and any other protective gear and properly dispose of it in the trash. Gloves should not be reused.
Wash your hands immediately after removing gloves with soap and water for at least 20 seconds.
Keep a small bottle of hand sanitizer (with at least 70% alcohol content) and a package of disinfecting wipes for use throughout the trip to minimize the spread of germs.
Download and print the cleaning checklist (available in the “Resources” section below) and leave one in your car after you clean and disinfect and before each trip to help make your guests feel safe and confident in your car.
* Please note these are recommendations, not requirements.
The pro detailers at AMMO NYC aggregate tips and best practices from the EPA, CDC, and WHO on how to clean and disinfect car interiors without damaging them.
Download the checklist to help guide you as you clean, and leave it in the car afterwards to reassure your guests that it’s been thoroughly cleaned and disinfected.
