Answer by  aprilmay33 (33)

Hydrogen peroxide (chemical name H2O2) has been approved by the US Environmental Protection Agency as an effective sanitizing agent. It can be used as a disinfecting agent to kill bacteria when sprayed onto cutting boards, counter tops, table tops, or other hard surfaces. However the Mayo Clinic does not advise the use of hydrogen peroxide in wounds.

Hydrogen peroxide does kill bacteria, but it can also kill cells that make up your skin and blood. Hydrogen peroxide causes the cells to explode when it reacts with oxygen.


Answer by  jamieellison (1637)

Yes, hydrogen peroxide does kill bacteria by breaking stealing electrons from the bacteria. Free radicals are created and a steady flow of continued damage ensures that the bacteria dies. Hydrogen peroxide is cheap and easy to find at drugstores. It often does not sting as much as alcohol would when disinfecting a wound.
