|The M11 pistol should be
disassembled into its major components and cleaned immediately after firing.
All metal components and surfaces that have been exposed to powder fouling
should be cleaned using CLP on a bore-cleaning patch. The same procedure is
used to clean the receiver. After it has been cleaned and wiped dry, a thin
coat of CLP is applied by rubbing with a cloth. This lubricates and
preserves the exposed metal parts during all normal temperature ranges. When
not in use, the pistol should be inspected weekly and cleaned and lubricated
using CLP, do not use any other type cleaner. Never mix CLP with RBC or LSA.
