DETERGENT COMPOSITION FOR REMOVING SCALE

FIELD: domestic chemistry, more particularly removing scale from metallic surfaces of heat-exchange devices, coiled pipes and other structural members of heat and power engineering systems, e.g. removing scale from internal walls of radiators of cooling system of internal combustion engines.

SUBSTANCE: detergent composition comprises Trilon-B, monosubstituted sodium phosphate, isopropyl alcohol, quartenary ammonium salt of perfluorosulfonic acid, ratios of components being as follows, wt %; (disodium salt of ethylene diamine tetracetic acid, 3.0-7.0; monosubstituted sodium phosphate, 3.0-5.0; isopropyl alcohol, 2.5-3.5; and water, the balance. Composition further comprises fluorescin in amount of 0.001-0.0015 wt %. Invention makes it possible to remove more effectively scale from metallic surface of heat-exchange devices including from treatment zones which are difficult to access.

EFFECT: improved properties of the detergent composition. 2 cl, 1 tbl
