How fast kills 70% ethanol

Dear newsgroupies,

We are a molecular biology lab, using mainly E.coli and mycobacteria in 
our research. We routinely spray 70% ethanol on surfaces etc to clean 
them after microbiological work. The ethanol is then wiped away almost 
immediately with a tissue.

But how fast-acting is 70% ethanol? Is a few seconds contact long enough 
to kill bacteria?  

TIA
