Introduction
In the reprocessing of medical devices, prevention of soil
from drying and fixation is very important. Recently,
pre-cleaning spray detergents are being used heavily to
prevent soil from drying before cleaning operations. On
the other hand, it is said that if soiled medical devices
are not reprocessed immediately and left drying, corro-
sion occurs due to the presence of chloride ions con-
tained in blood. With this, the effect of corrosion
inhibition of the pre-cleaning spray detergent on stain-
less steel in the presence of chloride ions and its
enhanced detergency were investigated.
Objectives
The effect of corrosion inhibition of the pre-cleaning
spray detergent on stainless steel in the presence of
chloride ions and its enhanced detergency were
investigated.
Methods
The effect of corrosion inhibition was observed in
appearance of stainless steel test pieces (SUS420J2) after
soaking in a pre-cleaning spray detergent solution con-
taining sodium chloride for a week. Its effect on the
detergency was then verified with test soils described in
ISO/TS 15883-5. After application of test soils to the
stainless steel test pieces, they were sprayed with pre-
cleaning spray detergents followed by manual or auto-
mated (washer disinfector) cleaning.
Results
Stainless steels corrode in the presence ofchloride ions,
and depending on the type of pre-cleaning spray deter-
gents, medical devices could corrode in the presence of
chloride ions contained in blood. In the novel pre-cleaning
spray detergent formulation, corrosion is still inhibited
even if the amount of chloride ions are two times of that
found in blood. Furthermore, as the corrosion is inhibited,
detergency is also being enhanced.
Conclusion
The formulation of the novel pre-cleaning spray deter-
gent exhibited corrosion inhibition of stainless steel in
the presence of chloride ions as the detergency is
enhanced, making it an excellent choice for a pre-clean-
ing spray detergent.
