Bacteria double and keep reproducing continuously. It is convenient to assume that this doubling occurs every 20 minute. Interestingly this means that a cleaning product that kills 99% of the bacteria on a surface and leaves 1% is up to 4% of the original number at the end of the first hour, 32% at the end of the second and back to full strength after another 40 minutes or so.
