Bleach for black mold?

I know that bleach will make the area appear clean but it won’t kill the mold. So I’m thinking about using hydrogen peroxide to kill the mold, but I read that bleach and hydrogen peroxide shouldn’t be mixed. Can I spray one first and then the other after? Or would it cause the same reaction as mixing them together?

    A bleach solution also works to kill mold. Mix one cup of bleach in a gallon of water, apply to the surface and don't rinse. You can also add a little dish soap to the bleach mixture to help the bleach penetrate porous surfaces, such as grout. When adding soap to the mixture, be sure to rinse after application.

    Bleach kills mold.  Peroxide is mainly water so does not do anything.  

    Pure Bleach does not need dilution as it is already diluted  to be 15 % bleach and the rest is water.  You can't buy 100% bleach.  The highest might be 18% avoid mixing with ammonia.(which is 15 % and the rest is water)

    If you don't believe me. pour some on your lawn.  It will die.

    same reaction as mixing them unless you clean the area in between with copious amounts of water

    Concrobium Mold Control works really good (it contains no bleach) available at most hardware stores.

    Bleach will work but will not prevent the mold from returning to the cleaned surface. It may look clean once you’re done, but the mold will grow back. Concrobium encapsulates the area and prevents future growth

    You need to consult a credible source.  Bleach DOES kill mold.  Dilute it 50:50.
