Preferably, said sequestrant is selected from the group of nitrilo triacetic acid (NTA), beta -alanine diacetic acid ( beta -ADA)), methyl glycine diacetic acid (MGDA), serine diacetic acid (SDA) and ethyl glycine diacetic acid (EGDA). Furthermore, the use of a detergent formulation containing said additive for cleaning bottles, in particular returnable plastic bottles, such as PET (polyethylene teraphthalate) or polycarbonate bottles is described.
