La présente invention concerne une composition et un procédé pour un traitement de blanchisserie, afin de le rendre plus sensible à un nettoyage dans le cycle de lavage suivant, en particulier en rendant le textile plus hydrophile, et améliorer le nettoyage de taches huileuses. L'objet de la présente invention est de décrire une composition qui améliore le nettoyage et l'élimination de salissures et taches huileuses après le lavage suivant. Nous avons observé qu'une composition de traitement de textile comprenant un sel de métal et un polymère carboxylique, en présence d'un acide organique et un polysaccharide, produit une bonne élimination de salissures huileuses après le lavage suivant.
