In
general, this is used as a topical antiseptic (in other words, on living
tissue to remove micro-organisms). I don=92t know that it wouldn=92t
function as a disinfectant, but I=92m not familiar with such a
use.

I am a
HUGE fan of OTC Hydrogen Peroxide, keep several bottles on-hand for
everything from disinfecting countertops to mouthwash to de-skunking the
dog after one of her annual encounters.

3%
hydrogen peroxide is an oxidizer. It can inhibit or kill
bacteria. It will also damage skin, so I personally do not allow
it to come into contact for more than about 10 seconds. 30%
peroxide is standard industrial strength material and it is a distinct
hazard - so I never allow contact of over a few seconds, and even
then there is damage done.
Stronger peroxides are dangerous. I know someone
who worked at a peroxide plant years ago. He was descending the
(circular) stairs between floors, when he heard a 'hiss". It was a
"weak" 70 or 80% line of material (they made up to 90 or 95%) that was
letting go. He jumped down about 15 feet, and was slightly
injured. His option was not jumping and being severly
injured.
