The tetraammonium salt of ethylenediamine tetraacetic acid is an effective agent for removing scale from naval boilers. The cleaning procedure effects significant savings in cleaning time and post-cleaning boiler readiness operations. However, the release of toxic ammonia gas into confined machinery spaces as a result of leakage and the corrosive effects upon alloys such as Monel and 2 14-1 chrome-molybdenum steel present serious doubts as to its employment for cleaning naval boilers.
