Hydrogen Peroxide is the best killer of MRSA that I know of.
Is that really true? I have my doubts.
Pulled from a “reliable” scientific source - Wikipedia:
Other bleaching applications are becoming more important as hydrogen peroxide is seen as an environmentally benign alternative to chlorine-based bleaches.[48] However scientific studies have found hydrogen peroxide to be ineffective in certain cases, and generally instruct hospitals, medical institutions, and other locations where public health is monitored, to use chlorine-based bleaches for disinfection.[49]
Although there are other products just out, e.g., HP bleach that is supposed to be the bees knees.
