Thanks everyone!  I also have never sprayed or wiped down anything going into or coming out of the incubator.  I've never used antibiotics and have never had a problem.  The lab I'm consulting for now does this paranoid wipe down and they lace their media with antibiotics and fungicide (and carry out their actual experiments with these additives in the media).

And leelee, if you use lab markers for labeling, you won't have to worry about your writing running or coming off.  They are resistant to most solvents including ethanol.  These are the only markers I allow in the lab.  I use the fine-tip for tissue culture and conical tubes and other big things.  For labeling microfuge tubes, I use the extra-fine-tip.  Black and blue are the only colors worth buying.  The red and green are a bit strange and hard to read.
