Can bleach evolve resistance to bacteria?

Can bleach evolve resistance to bacteria?

Can bacteria build soap resistance?

Unlike antibiotics, soap doesn’t use a molecular process to clean your hands – it uses a physical process. This means that soap doesn’t encourage superbugs: “Because soaps exert a physical action on bacteria and viruses, they do not lead to antimicrobial resistance,” says Lithgow.

Can viruses become resistant to disinfectants?

What is an example of a bacteria that becomes resistant?
