I follow a similar procedure. What I found comes in handy is to have a small cloth in a ziplock soaked with lysol.
If I have been touching surfaces such as shopping cart handle I can wipe the car door handle, wheel, gearshift etc and my hands. We are a bit short on sanitizer and I actually find the cloth easier to use.
BTW---Ch312 did have a point. If someone is passing very briefly thru your space all you need to do is hold your breath for a few seconds.
