Killing the mold isn't the problem. That's the easy part. Denaturing or removing the mycotoxins is the problem. The mold doesn't make you sick, it's the mycotoxins that some molds excrete that make you sick.
Look at this study that used gamma irradiation, detergent / bleach wash, and steam cleaning to test as ways to remove mold mycotoxins on paper, cloth, wood, and carpet. Unfortunately none of these techniques worked to inactivate mycotoxins, with two exceptions. A detergent / bleach wash worked to inactivate the mycotoxins on paper and cloth, but not on carpet or untreated wood. So porous surfaces must by physically removed and trashed to get rid of the mycotoxins. If you cannot physically remove it (like untreated wood that is a part of your houses' foundation), you must physically sand the mold off while using a HEPA vacuum to clean it all up.
