the mixture that you use at home is much weaker than commercial preparations sold for the purpose of killing molds (Spor-Klenz for ex). I wouldn't use one of those on clothing lol... but white vinegar and the strength of H2O2 you can buy at the market is pretty weak stuff... but works. yeah it off gases very little and don't stick your head in a bucket of it AND YOU WILL BE FINE... It is also much more effective at deodorizing your dog than tomato juice when it comes to skunk spray... ask me how I know lol.
