Extran® AP 21 The acid special cleaner can be used both as a prewash agent and a rinsing agent with a neutralising effect. When used as a pre-wash agent, it primarily dissolves carbonates and hydroxides from the residues. Protein substances and organic bases, such as amines, are often removed better in an acidic prewash as in an alkaline main wash cycle. As a rinsing agent, i.e. after the alkaline main wash cycle, it is especially suitable for removing remaining traces of alkali on the cleaned material or, in the case of solution carry-over, for neutralisation. This acidic cleaning agent is also well suited to the removal of calcareous deposits in the washing machine.
