Glock Cleaning Kit

A Glock cleaning kit built for a pistol that runs dirty and keeps running: carbon on the breech face and feed ramp, fouling in the barrel, and a slide that only needs a light film of oil on a few points. Everything in this collection is chemistry, not hardware, and it fits every Glock model and caliber, from a Glock 19 in 9mm to a Glock 22 in .40 or a Glock 20 in 10mm. GNP Defend Gun Oil was tested on the Glock 17 by the Military Institute of Armament Technology (WITU), opinion ZBUS-WITU-B3/4/2023.

Start with a kit if you are building from nothing. The Professional Go-To Kit packs the four products a Glock needs in three sizes, and the Range Bag With Gun Cleaning Set adds Synthetic Grease and a bag that keeps every can upright in the truck. Buying one can at a time: Gun Oil goes on light on the slide rails, barrel hood and connector, and stays put from a cold morning to a hot range session. Gun Cleaner strips carbon, copper and lead from the slide, breech face and feed ramp. Bore Cleaning Foam fills the barrel, dwells on the fouling and comes out clean on a patch. Degreaser goes on first to strip old oil and grit, and again before you lubricate. Synthetic Grease is the rail option for long range days, and Gun Cleaner Wipes handle the quick breech-face wipe between strings.

Not sure where the oil goes? Start with where to oil a Glock, with the lube points mapped, then how to clean a pistol step by step and why cheap pistol cleaning kits cause malfunctions. The same products serve every pistol caliber, so the 9mm Cleaning Kit collection is the same lineup framed for the caliber most Glocks are chambered in.

Frequently Asked Questions

What should a Glock cleaning kit include?

A cleaner for the slide, breech face and feed ramp (Gun Cleaner), a bore cleaner for the barrel (Bore Cleaning Foam), a degreaser to strip old oil and grit before you lubricate (Degreaser), and a light gun oil for the few points Glock's guidance names (Gun Oil). Brushes, rods and jags are caliber hardware you may already own; the products here are the chemistry that does the actual cleaning.

Was GNP Defend Gun Oil really tested on a Glock?

Yes. GNP Defend Gun Oil was tested on the Glock 17, alongside seven other service firearms, by the Military Institute of Armament Technology (WITU) in Poland, opinion ZBUS-WITU-B3/4/2023. The tests confirmed reliable function from -35 C to +50 C and zero corrosion at 81 to 84 percent humidity. That is a test of the oil on a Glock, not a Glock endorsement, and the WITU testing applies to the Gun Oil only.

Should I use grease on a Glock?

Glock's own guidance calls for a light oil on a handful of points: the slide rails, the barrel hood, the outside of the barrel where it rides the slide, and the connector. Gun Oil covers all of them. Synthetic Grease is an option for high-round-count range days, where oil burns off the rails; keep it thin, and keep it off the striker channel and the trigger housing.

How often does a Glock need cleaning?

Barrel, breech face and feed ramp after every range session. A carry Glock that has not been fired still needs a wipe-down and a fresh, light coat of oil about once a month, because lint and sweat pull moisture onto the slide and rails. Keep the striker channel dry and free of oil at every cleaning.
