Solvent cleaning is a process that uses chemical solvents to remove dirt, grease, and other contaminants from surfaces. This method is commonly employed in industries such as automotive, manufacturing, and electronics to ensure that parts are clean before assembly or further processing. Solvents can be organic or inorganic and are chosen based on the type of material being cleaned and the nature of the contaminants. The effectiveness of solvent cleaning depends on factors like the solvent's properties, temperature, and cleaning time. Common solvents include acetone, isopropyl alcohol, and mineral spirits. Proper safety measures are essential, as many solvents can be flammable or harmful if inhaled or absorbed through the skin.
