Application Procedure: CitriSurf is an excellent cleaner by itself for many cleaning and passivation
processes. However, to assure best results and help extend the life of the bath, the parts to be passivated
may be cleaned with an appropriate cleaning solution prior to treatment with CitriSurf solution, especially
when heavy grease and oils are present. For grades containing high carbon, sulfur, or selenium, preclean
using a good water based alkaline cleaner of pH $10 (see KleerKleen 4002). CitriSurf 3050 is an
emulsifying cleaner. If you need to skim oils from the cleaning tank, this should be done with a separate
cleaner prior to cleaning and passivation with CitriSurf.
