So Overall, What Cleaner is Better to Use in a Houshold?

Based on the risk/benefit analysis below, my recomendation for what is generally a better houshold cleaner would be white vinegar. Although chlorine bleach kills 99.9 of bacteria and kills many microogranisms resonsible for foodbourne illnesses, there are more risks to the cleaner than there are benefits. Bleach can be very dangerous around young children and pets, as it is full of toxic substances. If it is swallowed by a pet or child, it will cause sodium hypochlorite poisoning, which can cause death. It is also dangerous because if bleach is mixed with any other acid in the houshold ( toiletboil cleaner, vinegar, and ammonia) it can release toxic chlorine gas that you and your familey can inhale. When you clean with bleach, the fumes from it may irritate breathing conditions such as asthma or allergies. This does not seem like a cleaner i would like to use in my home. I would choose vinegar to clean my home with because it is a non-toxic and biodegradable substance. Vinegar is a very versatile cleaner, and can be used almost anywhere to clean a home. Also, no need to worry about a child or pet swallowing it, as it not toxic and will not cause harm. It kills 99.9 % of bacteria and has a high bacterial reduction. I believe that although bleach is a very effective cleaner, it poses more health risks when you clean with it, while vinegar poses barely any risks and is a safer and better substance to use overall in cleaning your home.

The Effectivness of Vinegar as a Disinfectant

Many people know that vinegar is a more eco-friendly disinfectant to clean their homes compared to the common chlorine bleach, but does it disinfect very well? The spokesperson for Heinz, Michael Mullen, says that 5 % solution of vinegar ( or higher), can kill 99.9% of bacteria, 82% of mold, and 80% of germs. The reason that Heinz White Vinegar is not listed as a disinfectant, is because the company has not registered it as a pesticide with the EPA . Another source that also claims bleach is 99.9% effective against bacteria is Gina Morino, Good Housekeepings microbiologist.  Some examples of the bacteria that Vinegar effectively kill are E.coli, salmonella and shigella.In white vinegar it is the acid that kills bacteria and viruses, which is done by it denaturing the proteins and fats that create the bacteria. Also the acrticle " Vinegar Works Wonders" states that microbiological studies have shown very high bacterial reduction after cleaning surfaces with white vinegar.  Therefore these are the facts on how vinegar is as a disinfectant.

The Effectivness of Bleach as a Disinfectant

Although bleach may have some dangerous effects on the environment and on human health, noone can deny that it is a very effective cleaner. The American Chemistry Council states that the use of chlorine bleach as a medical disinfectant was first recorded in Austria 1847. Medical staff used it to kill " childbed fever" that spreaded through the maternity wards.  The article " How Bleach Works" by Melissa Sandoval, states that chlorine bleach kills dangerous bacteria and viruses on surfaces. The article " What Are The Advantages of Using Bleach as a Disinfectant" by Shailynn Krow states that bleach kills 99.9 % of bacteria, viruses, mold/mildew. It is effective against most common pathogens, like tuberculosis, hepatitus B and C, and fungi. Bleach is one of the only houshold cleaning materials regulated by EPA ( U.S Environmental Protection Agency). This means that bleach has been tested and shown to kill microorganisms responsible for many foodbourne illnesses. The reason bleach is such an effective cleaner is because bleach quickely reacts with microbial cells to eliminate pathogens. Also, the sodium hypchlorite in bleach causes proteins to lose their structure, and these proteins are important for bacterial growth,so it kills bacteria, a research from the University of Michigan reveals.  An experiment performed by students from the University of North Carolina showed that Clorox (chlorine bleach) was able to effectively eliminate all human pathogens and antibiotic resistant bacteria included in the experiment, like poliovirus, while vinegar was less effective.In conclusion, bleach is a very good disinfectant .

Environmental and Health Concerns of Vinegar

Many people use vinegar to clean their homes as an alternative to bleach because they feel that it is safer and more environment friendly to use. The msds ( material safety data sheets) for white vinegar states that if you get it in your eyes, it will irritate and redden them. If you injgest a larger amount of vinegar it will cause irritation and pain in your stomach and that it is stable at room temperatures and pressure. Although, If vinegar comes in contact with strong oxidizers (such as bleach) it can become dangerous. You should never mix vinegar with bleach, as it will release toxic chlorine gas. People may not think,but vinegar can actually be good for your health. Many people put vinegar on their fries, and as a dressing to their salads, some may not know that this could be serving a health benefit to them. Vinegar can assist the body in absorbtion of essential minerals, so it is full of health benefits. Vinegar is a non toxic substance, and is not full of chemicals. Most of the vinegar that is used for natural health remedies is usually diluted. Therefore, these are some of the health risks and benefits of white vinegar.

When using vinegar to clean your homes, are you affecting the environment while doing so? The article  "Vinegar Works Wonders" states that vinegar is a natural organic bi-product of fruits vegetables and grains. This makes vinegar edible and biodegradable. If vinegar is biodegradable it means that it is capable of being decomposed by bacteria or other living organisms. Vinegar does not contain any harmful toxic chemicals so if you were to pour it down the drain after cleaning your houshold, it's affect on the water systems would be the same as any other food. Therefore these are the effects of vinegar on the environment when used to disinfect homes.
