>>I also try not to touch my face until I can wash my hands.
I keep disinfectant in my glovebox, make a point of not even touching the steering wheel before I've rubbed it into my hands after being in a supermarket. I'm still masking in places like supermarkets and drug stores so it's easy to remember as preparatory to taking the mask off.
Speaking of drug stores - I think of them as "places where people who are not feeling well go for cold remedies" so I'm extra careful there.
