Unless you’re butchering chickens inside the cabin I’d focus you’re attention on scrupulous hand cleaning, not touching your face, and other general cold/flu prevention techniques.
As a practical example, the typical flu virus can only survive on hard surfaces for 24-hours, on skin for significantly less. Unless you’re planning on disinfecting your car more than twice a day it’d be kind of a fruitless effort.
If the concern is avoiding getting sick or transmitting virus or bacteria within the vehicle, I’d suggest keeping some cleansing or disinfecting hand wipes in your truck and using them regularly, while doing routine interior cleaning with any commercially available product approved for those surfaces, they’ll be the best at truly cleaning the material (303 aerospace protectant fan here). Non-disinfecting hand wipes tend to be just as effective for cold and flu and don’t contribute to bacterial resistance, so it’s typically what we recommend.
