<p>Aqueous cleaning agent concentrate (A), for rough surfaces (preferably molded tiles and plates), based on non ionic, anionic, amphoteric surfactant and optionally under the use of usual auxiliary materials and additives, comprises at least a sorbitan ester (I) as cleaning amplifiers. Aqueous cleaning agent concentrate (A), for rough surfaces (preferably molded tiles and plates), based on non-ionic, anionic, amphoteric surfactant and optionally under the use of usual auxiliary materials and additives, comprises at least a sorbitan ester of formula (I) as cleaning amplifiers. R : optionally branched and substituted and/or hetero atom containing optionally saturated 6-22C acyl; R 1>, R 2>H or R; Alk : ethylene-, i-propylene- or butylene-; and a-c : 0-25 (where the sum of a+b+c is between 0-25).
