Definition - What does Detergent Cleaning mean?
Detergent cleaning is washing the critical surfaces of costly infrastructure with a cleansing agent to act as a corrosion inhibitor and prevent dirt particles from adhering to the surface. Detergents do not stick to metallic surfaces and make the surfaces slippery which in turn keeps the surface clean and prevents corrosion. As a part of additional protection, detergent cleaning helps to prevent acidic combustion and oxidation of metal surfaces.
Corrosionpedia explains Detergent Cleaning
In the operation of infrastructure projects, temperature plays a very important role as machinery often operates at high temperatures. The oxidation rate doubles with every 10 °C (50 °F) increase in temperature, and if not controlled, leads to decomposition of lubricants at the corners of metal or at critical areas of metal which with time may ultimately leads to sludge, resin, varnish, corrosive acid formation and ultimately corrosion in that area.
Detergent cleaning helps to neutralize acidic combustion and metal oxidation and also washes away any sludge, dirt or other impurity and thus helps to prevent corrosion. It also makes the metal's surface slippery and shiny.
