A review of modern classes of nonionic surfactants used for cleaning metal surfaces is carried out. The following aspects are considered: efficiency of cleaning metal surfaces, ecotoxicity, biodegradability, impact on human health. The most promising class of surfactants – alkyl polyglycosides (APG) – for cleaning metal surfaces, including in the process of capillary control, has been determined. It is noted that APGs have shown high efficiency in removing even such contaminants as denatured protein and burnt corn starch from metal surfaces. In addition, APGs have the highest emulsifying ability among industrial surfactants, which effectively affects the reduction in surfactant consumption when cleaning the surfaces.
