The invention relates to a composition for cleaning cellulosic fibre materials, comprising 3 ...50 % a mixture of non-ionic surface-active agents with a HLB of 4 ... 16, up to 50 % anionic surface-active agents, with HLB of 23 .... 40, 10 ... 30 % complexing agents, 10 ...40 % solvents, 10 ... 40 % hydrotrope products and water up to 100 %. The process for applying the cleaning composition consists in impregnating the textile material with a liquor bath comprising 0.4 ... 3 % composition, followed by a heat treatment in the presence of water at a temperature of 60 ...130 degree C, for 6 ... 120 minutes and finally washing. The resettling phenomena during the processes of later dilution are avoided, the reduction of the mass losses and the attainment of enhanced wettability are ensured.
