During an outbreak of a contagious viral disease, virtually any surface can become contaminated, especially if the virus is capable of surviving on surfaces for extended periods. As we know, an infected individual can spread respiratory viruses, such as COVID-19, by coughing or sneezing, contaminating nearby objects and surfaces. Once another person touches these contaminated surfaces, the virus can be transferred to their hands and potentially cause infection. Vehicles are among the environments where microorganisms can accumulate on frequently touched components. Depending on how often they are handled, different parts of a vehicle can be classified as high-touch or low-touch surfaces, each requiring appropriate cleaning and disinfection methods. Understanding how to properly disinfect your vehicle is essential for protecting both your own health and the health of your family.
High-Touch Vehicle Surfaces
Door handles, keys, control buttons, the steering wheel, gear shift, and dashboard are among the parts of a vehicle that are touched most frequently. Because of repeated contact, these surfaces are more likely to become contaminated with viruses and bacteria than other areas of the vehicle. Keeping a suitable disinfectant inside your vehicle can help eliminate harmful microorganisms from these surfaces. For this purpose, disinfectants containing quaternary ammonium compounds are recommended, as they provide excellent antimicrobial performance while minimizing the risk of discoloration, staining, or damage to interior materials.
Vehicle Glass Surfaces
Vehicle windows and other glass surfaces make up a significant portion of a car’s interior and exterior. Although these surfaces are generally touched less frequently than high-contact areas, studies have shown that viruses such as SARS-CoV-2 may remain viable on glass for several days under certain conditions. Therefore, it is advisable to clean glass surfaces once or twice daily using an appropriate glass cleaner or disinfectant, particularly during periods of widespread viral transmission.
Ventilation, Heating, and Air Conditioning System
Outside air enters the vehicle through the ventilation and air conditioning system, which may allow airborne particles and microorganisms to accumulate inside air ducts and ventilation components. Over time, these systems can become reservoirs for dust, allergens, and potentially harmful microbes. To disinfect ventilation ducts and air circulation compartments, disinfectant sprays formulated with quaternary ammonium compounds are an effective option. When applied correctly, these products provide long-lasting antimicrobial protection and help eliminate a broad range of microorganisms. Before disinfecting, however, it is recommended to remove as much dust and debris as possible from air filters and both the interior and exterior surfaces of the ventilation system to maximize cleaning effectiveness.
