Bleach can kill mold BUT it's effectiveness does depend on the surface the mold is on. Mold can grow and be visible on both porous and non-porous materials. When dealing with mold on non-porous materials such as shower tiles, tubs, vinyl window trims, counter tops, etc. you can use bleach to kill the mold and disinfect.

So what about mold growing on porous materials? In fact, using bleach to remove mold from porous materials like drywall and wood is said to aid in mold growth rather than killing it. Why is this? When bleach is used on porous materials like drywall and wood, the Iodine structure of bleach prevents Chlorine from soaking into the materials to kill the roots of molds and to make matters worse, the water element of bleach penetrates through the surfaces and feed the roots causing the mold to grow.

Consult a professional if you are not sure.

Boiling in water for fifteen minutes will kill most vegetative bacteria and inactivate viruses, but boiling is ineffective against prions and many bacterial and fungal spores (mold is a fungus); therefore boiling is unsuitable for sterilization. However, since boiling does kill most vegetative microbes and viruses, it is useful for reducing viable levels if no better method is available. Boiling is a simple process, and is an option available to most people, requiring only water, enough heat, and a container that can withstand the heat; however, boiling can be hazardous and cumbersome.

What is Mold?

Molds are fungi that reproduce by releasing tiny spores into the air. Spores lucky enough to land on moist objects may begin to grow. There are thousands of different types of mold and we encounter many of them every day, inside and out.

What is Toxic Mold?

Toxic mold is a type of mold that produces hazardous byproducts, called mycotoxins. While individuals with Asthma and other respiratory problems may have reactions to many types of mold, it's thought that mycotoxins are more likely to trigger health problems in even healthy individuals.
