I work for a company that cleans up things like mold, sewage, and crime scenes. We have lots of expensive commercial disinfectants on hand like Microban and some quat. am. disinfectants. These are designed for fungus, bacteria, and viruses. We even have one that is EPA approved for food surfaces. Would these be a good alternative to using bleach for disinfecting wood and stone? I find bleach to be very destructive and a lot more toxic than these other disinfectants.
