FIELD: technological processes.
SUBSTANCE: invention relates to cleaning of surface from sediments of various nature, namely to means for cleaning metal, ceramic surfaces of industrial equipment in form of solution and can be used for removal of such deposits as metal oxides, carbonate and salt deposits, asphalt-resin-paraffin and oil deposits, deposits of organic and biological nature. Solution contains, wt%: hydrogen peroxide 2–35; catalyst for decomposition of peroxide compounds 2–20, complexon 3–10, surfactant 0.1–5.0, antifoaming agent 0.01–1.00, water-soluble calixarene 0.01–1.00, water – the rest.
EFFECT: high efficiency of the solution for cleaning surfaces contaminated with deposits with high content of organic substances, while broadening the field of use thereof.
