Note: Bad Odor of chemical doesn’t mean good quality of pesticide and excess use of chemical is always harmful...
Sanitizing: Reducing the number of bacteria on a surface to a safe level.
Disinfecting: Complete removal or inactivation of bacteria, fungi and viruses on a surface.
Sanitization is a highly professional task that requires knowledge, experience, and expertise. Sanitization is the next step that aims at deeper cleaning.
Sanitization is a process of removing harmful microbes with the help of chemicals that doesn’t harm the human body. The chemicals are used in measured quantities and diluted with water or other diluting agents. Sanitization can also be done with the help of heat and some other methods but that cannot be applied in every context.
Sanitization is also a process of cleaning certain area or surface in such a manner so that it is made bacteria-free and elementally clean all types of microbes and viruses that can infect the human body and cause different kinds of diseases.
Disinfecting uses chemicals (disinfectants) to kill germs on surfaces and objects. Some common disinfectants are bleach and alcohol solutions. You usually need to leave the disinfectant on the surfaces and objects for a certain period of time to kill the germs. Disinfecting does not necessarily clean dirty surfaces or remove germs.
Germs are a part of everyday life. Some of them are helpful, but others are harmful and cause disease. They can be found everywhere – in our air, soil, and water. They are on our skin and in our bodies. Germs are also on the surfaces and objects that we touch.
Sometimes those germs can spread to you and make you sick. For example, there could be germs on a tv remote. You could get infected with the germs if you touch the remote and then rub your eyes or nose or eat with your hands.
