Abstract: The invention relates to the use of a composition comprising a C1 to C6 alkanol and a carboxylic acid ester of formula (I) wherein R1 is selected from a C1 to C6 alkyl, which may be unsubstituted or substituted by OH or F, and —X21—[O—X22]n—H; R2 is selected from a C1 to C6 alkyl, which may be unsubstituted or substituted by OH or F, and —X21—[O—X22]n—H; X21, X22 are independently selected from C1 to C6 alkandiyl, which may be unsubstituted or substituted by OH or F; n is an integer from 1 to 5. wherein, the C1 to C6 alkanol and the carboxylic acid ester are selected so as to form an azeotropic mixture and are present in an amount from 20% by weight below to 20% by weight above such azeotropic mixture.
