Abstract (en)
The invention relates to acidic aqueous compositions comprising sulphuric acid, a chelating agent having a pKa not higher than 4, and at least 0.1% by weight of the total composition of a surfactant,. Preferred compositions therein further comprise a source of active oxygen, or mixtures thereof, and/or a thickening surfactant system such as a quaternary ammonium compound together with a short chain amine oxide. Said compositions are particularly suitable for the cleaning of toilet bowls providing thereby improved surface appearance to the surface cleaned.
