The invention provides compositions useful in post-CMP cleaning operations where ceria is present. In one aspect, the invention provides a composition comprising a reducing agent; a chelating agent; an amino(C6-C12 alkyl)alcohol; and water; wherein the composition has a pH of less than about 8. The compositions of the invention were found to show improved ceria removal on, for example, poly silicon (poly Si) substrates. Also provided is a method for cleaning a microelectronic device substrate using such compositions and a kit comprising, in one or more containers, selected components of the compositions.
