FIELD: chemistry. ^ SUBSTANCE: composition contains the following in wt %: 0.01-10 malonic acid or its derivatives, 0.01-50 surfactant or polymer, where the mass ratio of polymer/malonic acid is between 1:1 and 20:1. The surfactant contains anionic and nonionic surfactant in ratio between 20:1 and 1:10. The method of removing dirt or spots from solid surfaces involves a step for successive treatment of the surface with dirt or spots with the composition, and the surface is cleaned to remove the dirt or spots. ^ EFFECT: high degree of cleaning surfaces, preferably from fat and spots. ^ 10 cl, 6 tbl, 6 ex |
