CBC-4 is Corbin's Benchrest Bore Cleaner, used for more
than 30 years at Camp Perry, Wimbledon, in the Armed Forces,
and in police armories around the world.
CBC removes fouling without chemical action, and is completely
safe to leave in contact with carbon or stainless steel
barrels. It is an oil-based dispersion of synthetic
sapphire scrubbing plates, which work their way under fouling
and pry it mechanically off the bore.
Since there is no chemical reaction, CBC works equally well with
plastic, powder, copper, lead, and moly fouling (yes, even
that build-up of caked on molybdenum disulphide that comes
from firing too many moly-coated bullets!).
The proper procedure is to use a brass brush one size smaller than
the bore, or a worn out brush of correct caliber for the
barrel, and wrap it with a cloth cleaning patch. The patch
should be a tight fit in the bore. Saturate the patch with
CBC, and squeeze out the surplus. Wrap it around the brush, and
stroke the brush through the bore, two inches forward, and
one inch back, in short strokes. When the patch emerges
from the other end, remove it and run one more patch in
the same way. Then wipe the bore with light oil or a
The amount of fouling removed from a bore in this manner
is amazing, even with a barrel you thought was clean before!
Two passes is sufficient for any barrel. If the fouling
or pitting is severe, use Corbin Bore Lap to smooth the
bore and remove tool marks.
