Pine sol actually does not kill bacteria...
it doesn't even inhibit the growth of bacteria at all.
in a recent experiment conducted. i tested 3 different concentrations of pine sol and compared it to bleach
at full concentration, pine sol didn't inhibit growth at all. whereas bleach completely killed it.
at 44% dilution, pine sol still hadn't stopped bacterial growth, whereas bleach still managed to kill of bacteria.
at 12.5% concentration, pine sol, had actually allowed the colonies of bacteria to grow even closer together to mimic the "lawned" streaks. bleach had still managed to kill bacteria at 12.5%
it should be kept in mind that in a standard lab, 10% bleach is used to sterilize and kill bacteria.
i hope that answers your question, pine sol, actually doesn't inhibit the growth, nor kills it, but allows it to grow
