Why Didn't It React?

Why didn't water kill the bacteria? It didn't kill bacteria because water does not remove bacteria from things. Why didn't the sanitizer kill bacteria? It doesn't have strong enough antiseptic cleaners in it. Why didn't the control work? It didn't work because the paper towel already had bacteria on it. The only reason bleach killed bacteria was cause there's a lot of chlorine in it to kill bacteria, and before hand we soaked the paper towel in bacteria so it killed the bacteria from the paper towel before hand which made it very sterile.
