Cleaning is the process of eliminating pollutants, pathogens, and other undesirable materials from a place or object. Cleaning is frequently done for aesthetic, hygienic, practical, environmental, or safety reasons. Cleaning is done in various locations and using various methods. Two key concepts—pH and physical removal—underlie all cleaning. Physical removal is one of the best microbiological cleaning techniques. It minimizes the number of germs on all surfaces in addition to removing the food sources that fuel their growth. Start by using your most delicate cleaning techniques, and only use more vigorous ones as necessary. Additionally, be knowledgeable enough about your cleaning supplies to stop using them before you cause harm.
