I use Chlorohexadine to clean my tubs but have recently been thinking of switching to bleach. One of my girls has an RI and I want to make sure I am cleaning as good as I can. Is bleach better to use, at least for the next couple months to make sure I kill any surfaces that may have any RI bacteria on it?

If bleach is better, what ratio should I use? I have seen 5%, 10% and even 50% bleach to water ratios that people have used on this forum. Thanks for any advice.
