Water-dilutable voc-free cleaning compositions

Abstract

Disclosed herein is a cleaning composition including: 40 to 90 wt.-% of glycol monoalkyl ethers (A); 10 to 60 wt.-% of hydroxy carboxylic acids (B); 0 to 10 wt.-% of surface active agents (C); and 0 to 10 wt.-% of further ingredients (D) which differ from (A), (B) and (C); all the above ingredients having a vapor pressure at 20° C. of less than 0.01 kPa, and/or an initial boiling point of more than 250° C. at a pressure of 101.3 kPa; and all wt.-% values being based on the total weight of the cleaning composition, and the combined amount of all ingredients being 100 wt.-%. Also disclosed herein is a method for removing a non-cured aqueous coating material from a surface making use of such cleaning composition or its dilution in an aqueous medium. Further disclosed herein is a method of using the cleaning composition, or its dilution in an aqueous medium, the method including using the cleaning composition or its dilution in an aqueous medium for cleaning substrates to which non-cured aqueous coating materials adhere.
