FIELD: domestic chemistry. ^ SUBSTANCE: invention relates to powder-like agents of sanitary-hygienic designation that can be used for removing pollutions from solid surfaces. Indicated agent comprises the following components, wt.-%: calcium carbonate (ground marble), 65.0-80.0; oxalic acid, 10.0-16.0; sodium carbonate and/or potassium or sodium hydroxide, 3.0-10.0; talk, 1.0-5.0; sodium sulfate, up to 100. Agent can comprise additionally 0.4-2.0 wt.-% of anionic or nonionic surface-active substance and 1.0-3.0 wt.-% of calcium hydroxide. Agent provides high effectiveness in removing pollutions and rust and reduced tendency for caking. ^ EFFECT: improved and valuable properties of agent. ^ 4 cl, 3 ex |
