Black Mold Removal with Ammonia
Always wear gloves and a respirator when working with ammonia based cleaning products. Never, ever, ever mix ammonia with chlorinated bleach.
Ammonia is a good disinfectant that does a good job of killing mold removal on non- porous surfaces such as sinks, counters, or shower doors.
However ammonia, like bleach does a pretty bad job at penetrating and killing porous surfaces such as particle boards, woods, tiles, etc. To kill molds on these types of materials, you need a solution that will penetrate to the root level.
