Isopropyl alcohol to clean germs on countertops
A 70% “rubbing” alcohol solution will kill those pesky bacterium usually in ten seconds or less. It will also kill a host of viruses, but not all of them. 

For your common household disinfecting, a 70% solution will do the trick. Especially for e. Coli, salmonella, staph, and a few others that would be risk bacterium when preparing poultry, etc. 

A final bit of information: 70% will be a more effective carrier than the 90-99% equivalent. Why? Because the water mix (30%) will act as a carrier or transport mechanism to get the alcohol into the bacterium cells in order to terminate them! The 90% mix simply is not very effective at penetrating the cell membranes.
