FIELD: domestic chemistry. SUBSTANCE: invention relates to chemical preparations used for removal scale deposits forming in heating and boiling water as result precipitation salts containing in water (CaCO3, MgCO3, CaSO4) from internal metallic walls of household devices, among them, washing machines, dishwater machines, steam generators and others. The proposed antiscaling compound contains the following components, wt. -%: sulfamic acid, 85-90; ammonium chloride, 8-10; thiourea, 0.5-1; nitrilotrimethylphosphonic acid. 1-4.5. Invention provides creature of inexpensive, ecologically safe and sparing composite for prevention of scale formation on walls of household devices. EFFECT: enhanced effectiveness of agent. 1 ex
