Preparing for Cleaning

Firstly, ensure you have a well-ventilated, well-lit area for cleaning. Your cleaning kit should include a cleaning rod, bore brush, patch holder, cleaning patches, gun oil, and solvent.

Cleaning Your P238

  1. Barrel Cleaning:
    • Dip the bore brush in solvent and scrub the interior of the barrel to loosen any residue.
    • Run a clean patch through the barrel to remove the loosened grime. Repeat with fresh patches until they come out clean.
  2. Slide Cleaning:
    • Use a small brush or cloth soaked in solvent to clean the interior and exterior surfaces of the slide, focusing on the breach face and rails.
  3. Frame Cleaning:
    • Wipe down the frame with a cloth lightly dampened with solvent, paying particular attention to the rails and any areas where residue accumulates.
  4. Recoil Spring Cleaning:
    • Wipe down the recoil spring with a clean, solvent-dampened cloth to remove any debris or residue.


  • Barrel and Slide:
    • Apply a thin coat of gun oil to the barrel, barrel hood, and the interior surfaces of the slide.
  • Frame:
    • Lightly lubricate the frame rails and other moving parts.
