Zusammenfassung:	The invention relates to a composition intended for the cleaning of contaminants and flux residues on electronic assemblies, particularly solder cream residue. Said composition comprises:from 20% to 99.5% by weight of a main solvent consisting of at least a C6-C15 glycol ether, and optionally a secondary solvent,from 0.5% to 20% by weight of a selected acid additive which is a phosphoric acid ester. The invention also relates to a defluxing product incorporating said composition, as well as to the defluxing methods using these products
