A composition comprising
- (i) a water-soluble alcohol;
- and
- (ii) an effective corrosion-inhibiting amount of ##STR15## wherein R is a C.sub.10 -C.sub.20 alkyl, alkeny, alkaryl, aralkyl, aryl, or cycloalkyl hydrocarbon group, R' is a divalent C.sub.1 -C.sub.5 lower alkylene hydrocarbon group, R"' is alkyl, aryl, alkaryl, or aralkyl, and NH--R" is an amino tetrazole group.
