Component
Cleaning
After
parts
are
disassembled,
they
may
need
to
be
cleaned.
Cleaning
methods
vary
according
to
the
characteristics
of
the
parts.
To
remove
oil
or
grease
contamination,
CSC
recommends
using
Simple
Green
or
other
similar
degreasing
agents.
Warning!
Never
use
gasoline
as
a
cleaning
agent.
To
remove
carbon
deposits,
use
mechanical
or
chemical
methods.
The
mechanical
method
uses
a
wooden
or
plastic
scraper
or
blade
to
clear
the
carbon
deposit
first,
and
then
rinse
the
parts
with
an
appropriate
cleaning
agent.
The
chemical
method
is
to
soak
the
parts
in
the
cleaning
agent
first,
then
clean
them
with
a
brush,
and
then
rinse
them
with
hot
water.
