Bristle Brushes
These are excellent cleaning tools on
silverware, jew elry and antiques. The three
shapes make it possible to get into tight
corners and other difficult places. Bristle
brushes can be used with polishing
compound for faster cleaning or polishing.
INCORRECT:
Excessive pressure can cause wire breakage.
CORRECT: Wire tips doing the work.
Brushing Pressure
1. Remember, the tips of a wire brush do the
work. Operate the brush with the lightest
pressure so only the tips of the wire come
in contact with the work.
2. If heavier pressures are used, the wires
will be overstressed, resulting in a wiping
action; and if this is continued, the life of
the brush will be shortened due to wire
fatigue.
3. Apply the brush to the work in such a way
that as much of the brush face as possible
is in full contact with the work. Applying the
side or edge of the brush to the work will
result in wire breakage and shortened
brush life.
