Restore your Glock 37 with an Ultrasonic Cleaner

Retaining the standard hand gun size, the Glock 37 hand gun features high power capacity with its large .45 caliber design. Ideal for big-bore biased users, the Glock 37 has the same reliability the Glock line is known for. Similar to all Glocks, the Glock 37 semi-automatic pistol has a Safe Action system and a standard 10 mag capacity. Proper and regular maintenance is necessary for top-notch working quality. The Glock 37 firearm should have both the main components and smaller parts cleaned inside and out.

If you own or service a Glock 37 Handgun or similar handguns you will definitely appreciate how an ultrasonic gun cleaner can save time and effort when it comes to cleaning and maintaining the weapon. An ultrasonic weapons cleaner is fast, thorough and safe because unlike some solvent washers and aerosol sprays, today’s ultrasonic gun cleaning solution is biodegradable, minimizing disposal problems with spent solutions.

  • How an Ultrasonic Gun Cleaner Works
  • How to Select and Set Up your Ultrasonic Weapon Cleaner
  • How to Disassemble, Clean and Reassemble your Glock 37 Handgun

How an Ultrasonic Gun Cleaner Works

Ultrasonic cleaners are used in a wide range of applications to remove virtually any soil or contamination with the power of cavitation action. Cavitation action describes the implosion of billions of minute bubbles in the ultrasonic cleaning solution as they contact all components of your Glock 37 Handgun. The bubbles are created by generator-powered ultrasonic transducers bonded to an ultrasonic cleaning tank and typically operate at an ultrasonic frequency of 37 to 42 kHz (37,000 to 42,000 cycles per second).

The imploding bubbles quickly and safely remove grease, powder residues and other contaminants that could interfere with reliable operation of your Glock 37 handgun. So tiny are the bubbles that they penetrate minute cracks, crevices and blind holes impossible to reach with conventional hand gun cleaning tools. The ultrasonic weapons cleaner will complete the job in less than 15 minutes. Meanwhile you can attend to other activities.

How to Select and Set Up your Ultrasonic Handgun Cleaner

A bench or table-top ultrasonic cleaner such as the LR617 along with its lubricating pan is ideal for sporting goods shops, servicing departments and the serious hand gun collector cleaning one or two handguns at a time. Whatever the model and size ultrasonic handgun cleaner you use there are steps to take before you start the cleaning operation by following the manufacturer’s operating instructions.

  1. Fill the ultrasonic weapons cleaner tank to the fill line (or approximately 2/3 full) with water and an ultrasonic cleaning concentrate diluted per manufacturer’s instructions. We recommend CLN-LR215 diluted 1 part to 10 parts of water.
  2. In the same way, fill the auxiliary lubricating pan with an ultrasonic gun lubricating solution and place it into the ultrasonic cleaner tank. Ready-to-use CLN-LR212 is a good choice. Make certain that the bottom of the lubricating pan is in contact with the cleaning solution.
  3. Turn on the ultrasonic cleaner and operate the unit for about 30 minutes to drive off cavitation inhibiting entrained air in both the cleaning solution and the lubricating solution. Degassing is complete when bubbles stop coming to the surface. Note that this step must be performed every time you use fresh cleaning or lubricating solutions.

How to Disassemble, Clean and Reassemble your Glock 37 Handgun

Step 1: Disassembling the Glock 37 Handgun

Safety tip! Ensure that the weapon is not loaded. Remove the magazine and any rounds in the chamber. Field strip the Glock 37 pistol.

Push out the headless pin in the area above the trigger of the Glock 37 frame. Remove the slide release or slide drop. Gently pry out the locking block. To remove the trigger assembly, push out the plastic pin on the back of the frame. Lift out the trigger assembly and trigger housing; this should come out in one piece. Wriggle out the trigger or action bar carefully.

Proceed with the disassembly of the slide. Hold the back plate down with your thumb. Press down in the gap near the firing pin with the Glock pin or a punch. Carefully push unto the back spring. Slide out the back plate and pull out the firing pin. Remove the extractor plunger. Push down on the firing safety piece and the extractor should drop out. Carefully remove the small spring.

Voila! Your Glock 37 hand gun has been successfully disassembled. Its parts are now ready to be cleaned using an ultrasonic cleaner.

Step 2: Cleaning the Glock 37 Handgun

Use the weapons kit brushes and tools to remove powder residues, bullet shavings, carbon and other loose contaminants. Tip: If the weapon is extremely dirty it should be cleaned using hot water to prepare the cleaning bath.

Put the hammer in the cocked position. Lift the star shell ejector and place a spacer between the star and cylinder to enhance cleaning action. Position your weapon parts in the mesh basket in a way to avoid air entrapment. Lower the basket into the cleaning solution and set the timer for 7-10 minutes. Cleaning time depends on the condition of the weapon.

At the end of the cycle remove the handgun components from the bath. If they are not clean replace them in the bath until the cleaning is complete. Do not reach into an operating ultrasonic bath. Remove the basket from the bath if you want to inspect or rearrange the parts.

After cleaning rinse the parts in fresh water to remove all traces of the cleaning solution, shake them to remove excess water and allow them to drain. Compressed air will aid in this process.

Return the weapon parts to the basket.

Next place the lubricating pan into the ultrasonic cleaner again making certain that the bottom of the lubricating pan is in contact with the ultrasonic cleaning solution. Put the basket into the lubricating solution and set the timer for 10 minutes. Ultrasonic waves will pass from the ultrasonic cleaning bath to the lubricating bath and thoroughly lubricate the weapon parts.

After the lubricating step remove the parts and allow them to drain. Do not blow dry. Inspect then oil the parts according to the manufacturer’s instructions before reassembly.

Step 3: Reassembling the Glock 37 Handgun

After you’ve cleaned the parts of your Glock 37 pistol with an ultrasonic cleaner, start reassembly with the slide. Insert the extractor plunger and the extractor in place. Push the firing pin safety piece in place. Insert the firing pin into the slide. Use a punch or similar tool to fit into the gap below the firing pin and push on this. As you do this, partially slide in the back plate. Keeping the back plate in place, press down on the ejector plunger, and fully slide the back plate in.

Reattach the trigger bar unto the housing. Through the top of the frame, drop in this trigger assembly. Push in the short headless plastic pin into the back of the grip. Put in the locking block and then the slide release lever in. Push in the locking block pin. To replace the trigger pin, gently jerk the slide release lever as you push this pin back in.

Ensure the pieces are aligned. Check and test the frame through rack and cycle. Now assemble the Glock 37 hand gun together with its slide, barrel, recoil spring and its frame.

Congratulations! You have just reassembled your “brand new” Glock 37 Handgun.

Additional Weapon Cleaning Tips

Oils that rise to the surface of the bath should be skimmed off and disposed of properly. When the ultrasonic handgun cleaner solution becomes discolored or cleaning takes longer it is time to replace it. Drain the tank and dispose of the spent solution according to local regulations. Take the time to remove sludge that settled to the bottom of the tank then clean the tank.
