FIELD: chemistry. ^ SUBSTANCE: invention relates to cleaning composition for treatment of products made of aluminium and aluminium alloys and cleaning method. Cleaning composition includes water and alcohol ethoxylate, allowing formula R1-OH, where R1 corresponds saturated or nonsaturated aliphatic compound with unbranched or branching chain, containing from 12 up to 80 carbon atom, inorganic component, regulating pH, present in such amount that, pH of cleaning composition is less than 2 or is in the range from 9 up to 13, and at least one surface-active agent, version the described above ethoxylate. Cleaning composition allows reduction of average percentage value of free from ruptures aquatic film area after 7 days of aging less than 50%. Cleaning method of the surface includes its contacting with specified cleaning composition with sufficient temperature and during sufficient period of time for cleaning. ^ EFFECT: cleaning composition allows durability, safety, low level of foaming and increased biodegradation. ^ 63 cl, 7 tbl, 1 ex |
