2.1.5.3 Immersion in cleaning tanks is usually used for disassembled
parts submerged in an authorized cleaning compound(s).
Since the cleaning compounds may act as an
electrolyte between two or more metals, care shall be taken
not to intermingle the different metals together in the same
cleaning tank.
2.1.5.4 Use of foamers involve injecting air into a tank containing
a soap solution, which rapidly mixes the air and solution
as it leaves the tank via a hose. This process produces a
very thick, foamy solution that adheres well to the exterior of
the SE allowing the cleaning solution to maintain contact with
the surface being cleaned.
2.1.5.4.1 The solution is allowed to dwell on the SE briefly,
scrubbed with wash pads or mops, then is rinsed off the SE
with fresh water.
2.1.5.4.2 Detergent can be added at a pre-set and controlled
rate when using foamers or pressure washers for SE cleaning.
Therefore, these methods are preferred over hand washing,
which cannot regulate the amount of detergent used.
2.1.6 Cleaning Materials. An effective cleaning program
significantly reduces the adverse impact of corrosion. The
cleaning program includes the selection of authorized cleaning
materials, mixed in the proper ratio for the surface to be
cleaned, properly applied, and removed.
2.1.6.1 Material compatibility is a key element in a cleaning
program. Cleaning material composition and surface condition
affect the methods and materials to be used in cleaning. Certain
nonferrous metals, such as zinc and aluminum, present
special problems because heavy-duty alkaline or strong acid
cleaners attack the metal. Roughness of surface tends to hold a
soil, thereby making it harder to remove.
