The present invention provides a composition containing component (A): a compound represented by the formula (1)

##STR00001##

wherein each symbol is as described in the DESCRIPTION, or a salt thereof, and component (B): at least one kind of surfactant selected from the group consisting of an anionic surfactant having a carboxyl group, an amphoteric surfactant and a nonionic surfactant, which is superior in foamability and foam volume and affording improved rinsing performance and smooth feeling after drying.

Embodiments of the present disclosure generally relate to methods for detecting end-points of cleaning processes for aerospace components containing corrosion. The method includes exposing the aerospace component to a first solvent, exposing the aerospace component to a first water rinse, and analyzing a first aliquot of the first water rinse by absorbance spectroscopy to determine an intermediate solute concentration in the first aliquot, where the intermediate solute concentration is greater than a reference solute concentration. The method further includes exposing the aerospace component to an aqueous cleaning solution to remove corrosion from the aluminum oxide layer, exposing the aerospace component to a second solvent, and exposing the aerospace component to a second water rinse, and analyzing a second aliquot of the second water rinse by absorbance spectroscopy to determine a post-clean solute concentration in the second aliquot, where the post-clean solute concentration is less than the intermediate solute concentration.
