FIELD: cleaning solid surfaces from dirt.
SUBSTANCE: removal of fatty dirt from surface includes the following stages: (a) treatment of surface with composition containing detergent-surfactant and anti-oxidant; (b) setting of dirt; (c) cleaning the surface for removal of dirt. Anti-oxidant is used for preparation of liquid product and removal of fatty dirt settled on surface; anti-oxidant is selected from tannic acid, tannates and tannic acid salts; liquid has pH7 of below. It is good practice to use natural anti-oxidants. Liquid composition contains 0.05-45% of detergent-surfactant and 0.1-10% of natural anti-oxidant having 1,2- or 1,4-dihydroxybenzene substructure. Liquid composition has pH below 12 and viscosity lesser than 100 Mpa.s at shift rate of 21 s-1.
EFFECT: enhanced efficiency of cleaning.
