10 simple steps: how to clean a glock

Cleaning a Glock 19 or any firearm is an essential part of responsible gun ownership. Here’s a general guide on how to clean a Glock 19:

Note: Always ensure your Glock 19 is unloaded and pointed in a safe direction before starting the cleaning process. Follow these steps carefully, and if you’re unsure, consult the Glock manual or seek professional assistance.

Materials Needed:

  • Gun cleaning solvent/lubricant
  • Bore brush
  • Cleaning rod
  • Cleaning patches/cloth
  • Nylon brush
  • Toothbrush or soft-bristle brush
  • Gun cleaning patches or cloth
  • Microfiber cloth
  • Gun lubricant


  1. Unload the Firearm:
    Remove the magazine and visually/physically inspect the chamber to ensure it’s empty.
  2. Field Strip the Glock:
    Follow the steps for field stripping your Glock as mentioned in the Glock manual. This involves removing the slide and barrel from the frame.
  3. Clean the Barrel:
    Attach a bore brush to the cleaning rod. Dip the brush in solvent and run it through the barrel from the chamber end. Repeat several times. Then attach a cleaning patch to the rod, dip it in solvent, and run it through the barrel to remove fouling.
  4. Clean the Slide:
    Use a nylon brush or toothbrush to clean the slide’s exterior and interior parts. Pay attention to areas like the breech face, extractor, firing pin channel, and slide rails.
  5. Clean the Frame:
    Use a nylon brush or toothbrush to clean the frame’s interior parts, including the trigger mechanism and magazine well.
  6. Wipe Down:
    Wipe down all parts with a clean cloth or gun cleaning patches to remove excess solvent and residue.
  7. Lubricate:
    Apply a small amount of gun lubricant to the recommended areas mentioned in the Glock manual. These typically include slide rails, barrel hood, and contact points.
  8. Reassemble:
    Carefully reassemble the Glock 19, following the steps outlined in the Glock manual.
  9. Function Check:
    After cleaning and reassembling, perform a function check to ensure the firearm operates as expected. Check the trigger, slide, safety features, and magazine release.
  10. Exterior Finish:
    Wipe down the entire firearm’s exterior with a microfiber cloth to ensure it’s clean and dry. This helps prevent moisture buildup.

Regular cleaning is crucial for firearm maintenance and longevity. If you’re new to cleaning firearms, consider seeking guidance from a certified firearms instructor or gunsmith. Always refer to the Glock manual for specific cleaning and maintenance instructions for your Glock 19 model.
