Cleaning is an important part of any home environment, and it is necessary to clean not only the external surfaces but also the internal parts. Cleaning theory states that when visible dirt and messes are removed from an area, they are displaced by air or other contaminants. This in turn creates a negative environmental effect that can lead to disease.
In order to clean effectively, you need to understand the different types of cleaning agents and their effects on different materials. For example, detergents work well on oil and grease substances but will leave soap scum behind. Acids work best on artificial colors and adhesives but may damage non-porous hardwood floors or fabric walls. Sprays are effective for removing dust mites but may be harmful if inhaled pesticides are used in large quantities on a regular basis.
Cleaning and disinfecting are based on the principle of germicidal action. This means that chemicals or solutions kill microorganisms by causing damage to their cellular membranes. Disinfectants also act against viruses by preventing them from attaching to host cells. Sterilization is achieved through the use of heat, radiation, or chemical agents that destroy all forms of microorganisms present in a product or environment.
This exam sounds simple enough. When it comes to cleaning I've learned a lot from window cleaning Victoria BC. The principles of sanitizing and disinfecting are to sterilize surfaces which might be dirty enough to detriment our health. But something like cleaning windows can also be simply to have a clearer view and might be different than the purpose of sterilizing bacteria.
