A box of Lysol wipes on either side of the door would handle that possible decontamination problem.
Or an old Swipes box with tough tissues, on either side of the door to which you could add more 10 - to -1 diluted bleach on your own (Cheaper-just as effective).
Remember : D I Y , and save .
I tend to use either bleach or vinegar, lemon peels, and a drop of soap for most cleaning jobs around the house, sometimes a little baking soda.
For anything contagious, I always go to bleach and papaer towels or cleaning rags, that are then boiled with bleach and soap before throwing in the washer.
