cleaning
Manual or wipe on/wipe off is the simplest method of cleaning,
virtually no equipment is required, but workers are more likely
to be exposed to the chemicals. Using a suitable cleaning formula,
an operator suitably protected by rubber gloves, eye protection,
and apron wipes the soiled workpieces with an agent-impregnated
cloth or sponge, also mops or brushes are used. After the cleaner
is allowed to react (2 or 3 minutes is usually sufficient),
work is rinsed with water.
The wiping method is practical only for cleaning a few parts
at a time or for large, bulky parts that cannot be immersed
conveniently in a cleaning bath. Labour cost becomes excessive
if many parts are cleaned. Cleaner concentrations are stronger
than in dip and spray solutions, and the cleaner is not usually
recovered for further use.
Wiping generates more waste than other processes. The wipe material
becomes contaminated with the cleaning chemical and soil. The
requirements for disposal of the cloths may depend on the solvent
and soils removed.
