Compositions are disclosed which are suitable for the safe cleaning of delicate surfaces, i.e. marble and lacquered surfaces, e.g. lacquered wooden floors. The compositions disclosed herein comprise at least one anionic surfactant, they are free of strong builders, they are formulated in the mildly acidic to mildly alkaline pH range, and they comprise positive divalent ions in amounts so as to saturate the anionic surfactant in the composition.
Ces compositions se prêtent au nettoyage sans risque de surfaces fragiles, du marbre ou des surfaces laquées, des parquets vernis par exemple. Elles comprennent au moins un agent tensioactif anionique mais aucun adjuvant agressif, leur formulation correspond à une fourchette de pH allant de légèrement acide à légèrement alcaline, et elles contiennent des ions divalents positifs en des quantités propres à saturer l'agent tensioactif anionique.
