There are many situations in which you may think that use of bleach as a cleaner/sanitizer is effective. Indeed, there are certain restoration projects, such as sewage backflows, floods, and even mold remediation, where individuals have been taught to use bleach as part of their restoration protocol. This history is supported by continuing references in publications put out by numerous organizations including the EPA, American Red Cross, Salvation Army and others.
Despite this surge in bleach use for restoration of water-damaged and mold-impacted environments, You should not be using bleach for cleaning, sanitizing, or disinfecting surfaces! 
So the question that is obvious is, Why is this environmental expert so adamant about not using bleach? The answer is related to both practical implications.
Bleach is favored by many because of its long history of use by homeowners for cleaning and stain removal. Its relatively low cost has made it so widely available that its odor is now commonly associated with cleanliness by the general public. But in contrast to this widespread use are its dangers. Bleach is a corrosive that can irritate and eventually cause considerable damage to the skin. Bleach releases chlorine gas as it is sprayed or evaporates. The effect of bleach vapors on the eyes and respiratory system are immediately evident to anyone who is in an area where the product is being used liberally. Because of these potential effects on the body, appropriate personal protective equipment such as gloves, goggles, and respirators should be employed when bleach is utilized for situations beyond laundry. However, such essential precautions are often ignored because of the product’s acceptance in the mainstream of our society.
There are many practical impacts of bleach use beyond health concerns. You must appreciate the highly reactive nature of this chemical compound. The fact that bleach is used for stain removal and whitening means that it can also discolor and damage many fabrics. Less obvious is how bleach reacts with other materials. It is corrosive to many metals and stone products. It should never be used on stainless steel, aluminum, copper, brass, marble, or granite. In fact, bleach is so strong that it will etch glass if it is not neutralized after application to surfaces such as mirrors and windows.
A BAD REACTION
The reactive nature of bleach is even more troublesome when it is mixed. Bleach should never be mixed with acids, as dangerous fumes are usually the result. Even a mixture of two innocuous cleaning compounds such as bleach and ammonia can produce deadly gasses that can kill with just a few breaths. Depending on the ratio of bleach to ammonia, chlorine gas, nitrogen trichloride and/or hydrazine will be produced when these two are mixed. In addition to being toxic the last two listed by-products from this bleach mixture are also explosive. Other reactive by-products that can come from bleach mixtures are toxic chloramines and dioxins.
Perhaps the most misunderstood aspect of bleach when proposed as a cleaner or sanitizing agent is that its effectiveness is greatly reduced in the presence of organic material. To be a successful sanitizer, bleach must be used on clean materials and surfaces. This is why bleach products are used in the laundry after the wash cycle or in a commercial kitchen as a component in the third sink after the dishes have been washed and rinsed. The efficacy of bleach as a sanitizer is also compromised by heat and light. Despite the fact that the chlorine odor may linger for some time after use, bleach loses strength so quickly that it is not considered to have a residual effect that would prevent future bacterial or fungal growth.
Their cost effectiveness and ease of use, many sanitizing products promoted by the EPA such as vinegar to fungal regrowth.
