CLEANING AND SANITIZING- washing chemical slideshare ,2. Washing - the application of the cleaning compound. There are many methods of subjecting the surface of equipment to cleaning compounds and solutions. Effectiveness and the economy of the method generally dictates its use. A. Soaking - immersion in a cleaning solution . The cleaning solution shouldDetergents and Surface Tension – Explanation, Effect ...The effect of detergent on surface tension brings a non-adhesive nature to water molecules. It does not stick to the surface of the glass. It happens because of the cohesive force in the water-detergent molecule. The exact thing appears when it comes to washing clothes with water. Water can’t help much to clean the dirt.

Sterilization and Disinfection

Sterilization can be achieved by physical, chemical and physiochemical means. Chemicals used as sterilizing agents are called chemisterilants. Disinfection is the process of elimination of most pathogenic microorganisms (excluding bacterial spores) on inanimate objects. Disinfection can be achieved by physical or chemical methods.
