Abstract (en)

[origin: EP0686693A2] A cleaning composition for pretreatment of baked on soil, said composition comprising: a) at least 2%wt of a surfactant, preferably a primary alcohol sulphate having a chain length of C10-C14, b) 0.01-5.00 of a metal-complexing agent (such as an amino phosphonic acid), wherein the pH of the neat composition is below 13.0 and the pH at an aqueous dilution of 1% is greater than 10. The invention also relates to a method of cleaning baked on soil from surfaces which comprises the steps of: treating the surface with a composition as described above in substantially undilute form, whereby the baked-on soil is loosened from the surface, and, treating the surface with a second surfactant-containing composition, said second surfactant containing composition comprising less than 2% of surfactant.
