Abstract

An aqueous cleaning solution is described and is characterised in that it contains a fast-wetting surfactant selected from the group comprising sulphosuccinic acid, fluorinated surfactants and secondary alkanesulphonates with a wetting time (measured in the Draves test) of less than 20 seconds at a concentration of 0.3 % by weight and 25 DEG C, and an inorganic or organic acid with a pKa of >2.5, and has a pH not exceeding 4.0. This cleaning solution is very suitable for rapid, simple and efficient cleaning of diagnostic analysis systems with a single cleaning composition.
