A composition for removing residues and method using same are described herein. In one aspect, the composition comprises: an organic polar solvent; water; a quaternary ammonium compound; and a mercapto-containing corrosion inhibitor selected from a compound having the following formulas (I), (II), 2-mercaptothiazoline, 3-mercaptopropyl-trimethoxysilane, and mixtures thereof:
wherein X, Y, and Z are each independently selected from C, N, O, S, and P; R 1 , R 2 , R 3 , R 4 , R 5 , and R 6 are each independently an alkyl group having a formula C n H 2n+1 ; R 7 is one selected from H, -OH, -COOH, and -NH 2 ; and R 8 is selected from an alkyl group having a formula C n H 2n+1 , or an alkanol group having a formula C n H 2n OH; n ranges from 0 to 20; and the composition is substantially free of a water soluble amine. In another aspect, the composition comprises hydroxylamine wherein the mass ratio of hydroxylamine to quarternary ammonium compound is less than 3. |
