This paper presents the results from an investigation undertaken to compare the relative
effectiveness of four Chemical Rinse Agents (CRAs) used for rinsing aircraft. The
products were applied on a weekly basis to a series of flat alloy panels exposed to an
oceanfront, marine atmospheric environment for two years. The results are presented
and compared to those obtained from exposures of the same alloys that were not
washed, were washed with ocean water, or washed with demineralized water. This
report is a part of an ongoing study. Only the results of the exposures of aluminum
alloys are presented in this report.
