Clean Outside of Gun

The solvents listed in this section may ignite if used in flushing. Use them only for external cleaning.

Wipe the outside of the gun with a compatible solvent. See materials of construction info in Technical Data, page 55. Use N-Methylpyrrolidone (NMP), Dynasolve CU-6, Dzolv, or an equivalent solvent to soften cured material. Applying a light coat of lubricant will make future cleaning easier.
