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.
