Abstract:
Cleaning compositions include (a) a carrier liquid; (b) a metal citrate and/or a plurality of reagents configured to generate the metal citrate in situ; (c) one or a plurality of non-ionic surfactants; and (d) an organophosphate hydrotrope configured to increase solubility of the one or the plurality of non-ionic surfactants in the carrier liquid. Methods for cleaning engine cooling systems are described.
