Beschreibung
Zusammenfassung:	La presente invención se refiere a un método para separar residuos orgánicos de una superficie contaminada, que comprende: a) poner en contacto la superficie con una composición que comprende cuando menos un éster de ácido dibásico y de 0 a aproximadamente 40 por ciento en peso de un agente tensioactivo emulsificador apropiado; b) dejar que continua el contacto durante un tiempo suficiente para solubilizar el residuo; y c) separar la composición y el residuo solubilizado, de la superficie. Methods and compositions are provided for the removal of soldering flux, screen inks and resists from contaminated surfaces. The compositions of the invention contain dibasic acid esters in combination with an appropriate emulsifying surfactant.
