How Often Do You Have To Clean a Gun (Really)?

Sure, keeping your guns clean is crucial, but don't overdo it. My dad, a Vietnam War vet, passed on the military tradition of cleaning your gun after every use. It dates back to the 1950s, but I eventually broke free from the habit. If you're a stickler for cleaning your gun every time you shoot, maybe it's time to reconsider - just like I did.

Looking back at the history of gun cleaning, when black powder ruled, it was a must. That stuff left a corrosive mess, and if not cleaned promptly, your gun could turn into scrap metal. The military caught onto this early, and even with the shift to noncorrosive smokeless powder, the practice stuck around.

But is it really necessary? Gun cleaning gear manufacturers might want you to believe so, but think about it. If you clean carbon fouling after every use, why not after every shot? It's a slippery slope. With modern smokeless powders, gun cleaning doesn't have to be a daily ritual.

Gun cleaning gear manufacturers would love for you to heed this advice because it means more sales for them. But think about it: if you're expected to clean carbon fouling after every use, why not after every single shot? The same logic applies to barrels - if you're required to scrub out carbon, copper, and lead fouling after each use, then why not after every shot?

We invest a considerable amount of money in our firearms, naturally wanting them to endure for as long as possible. If you find satisfaction in cleaning your gun, go ahead - make it a nightly ritual, clean it before, during, and after use. Heck, pull it out of the safe every month for another cleaning session. However, the reality is, with modern smokeless powders, thorough gun cleaning is only essential under specific circumstances.

When To Clean...
Experience is a great teacher, and with over fifty years of handling guns, I've picked up a thing or two about gun cleaning. Just like I don't clean my car every time I take it for a spin or my oven after every use, I certainly don't feel the need to clean my guns every time I pull the trigger.

I've crafted a straightforward cleaning guide over the years, and I recommend you do the same. In this fast-paced world, time is a valuable commodity. Though a day remains 24 hours long, they don't stretch as far as they used to. Understanding when your gun truly requires cleaning and when it doesn't empowers you to manage your time efficiently and avoid unnecessary expenses on high-end gun-cleaning gear.

#1: Give your gun a good cleaning when you notice it acting up
Firing a gun inevitably results in accumulating dirt. If you're a frequent shooter, these deposits can detrimentally affect your firearm's performance. This is particularly true for gas-impingement-driven, semi-automatic guns like the AR-15, as they can accumulate carbon, copper, lead, and plastic deposits in the bore, potentially degrading accuracy. Magazine-fed guns face reliability issues when magazines gather dirt and debris from being dropped on the ground.

If you notice a decline in reliability or accuracy, it may signal the need for a cleaning session. Additionally, such issues could indicate an underlying problem. Regardless, it's time to initiate the Preventive Maintenance Checks and Services (PMCS) process. Ideally, you should be familiar enough with your firearm to prevent it from reaching the point where dirt becomes a problem.

I once owned a Cooper rifle chambered for .257 Roberts, renowned for its precision. However, after approximately 25 rounds, accuracy significantly suffered due to copper fouling, compelling me to clean the rifle's bore. This illustrates how copper fouling can impact accuracy. Eventually, I decided to part ways with that rifle because I had better uses for my time than cleaning it after every box of ammunition.

During my participation in police pistol competitions, my 1911, loaded with handloaded lead bullets, would start cycling sluggishly after about 150 rounds. To address this, I'd perform a thorough field strip between matches and conduct a comprehensive cleaning routine. Understanding the fouling tendencies of both these guns, I implemented PMCS before fouling became a significant problem.

#2: Give your gun a once-over if it gets wet.
Sure, most modern firearms are decked out with fancy coatings that resist corrosion like champs. But no matter how well a wood stock is sealed or how space-age a coating might be, there's always a vulnerable spot. Maybe it didn't get sealed properly, wasn't coated, or just got a bit worn.

Moisture has a knack for finding these weak points, and it doesn't have to be a downpour or a snowstorm - even humidity can play the invisible corrosive. So, after any run-in with moisture or extreme humidity, it's a good call to break down your gun, give it a wipe-down, and throw on a light coat of gun oil on all the metal parts, whether they're stainless-steel or coated.

#3: Give your gun a clean-up when it gets grubby.
I'm not referring to the carbon or copper fouling kind of dirt; I'm talking about the everyday dirt and debris that can sneak its way onto or into your firearm. Guns and dry, dusty environments don't play well together. While guns need lubrication to function smoothly, using gun oil can attract dust, turning your gun into a mess of dust-induced oily mud that it's not designed to handle.

Just as you need to be on guard in wet conditions, staying on top of Preventive Maintenance Checks and Services (PMCS) is essential in dry climates. Compressed air becomes your go-to tool, along with the occasional but not excessive application of lubrication.

#4: Clean your gun for long-term storage.
If you're savvy, you've got a gun safe equipped with humidity control for those prolonged storage stints. While this doesn't completely eliminate the necessity for corrosion-resistant gun oil, it certainly lends a hand. In my line of work, I frequently take various guns out for a spin. As a result, most of my firearms hardly go a month without a trip to the firing range.

However, I've got a few guns in my collection that seldom see the light of day or hear the crack of gunfire. It could be because they serve very particular purposes or are precious heirloom pieces. But when I do decide to take these less-used firearms for a spin, I make sure to give them a comprehensive cleaning before tucking them away. It's not just about preserving their condition; it's also about ensuring I know their state the next time they make an appearance.

Mastering Preventive Maintenance Checks and Services (PMCS)
Taking care of most mechanical devices typically follows a set schedule. If you've had military experience, you're well-acquainted with PMCS, governed by a time or usage chart. After a specified number of days or usage, there are recommended checks and cleanings. The key term in preventive maintenance checks and service is "preventative". PMCS aims to avert failures rather than address them.

For instance, if you're a precision shooter covering long ranges, there are checks to perform before, during, and after every match or range session. Some services need scheduling at specific intervals. Perhaps you own a rifle like my trusty .257 Roberts, requiring bore cleaning after a certain number of shots. It's crucial to inspect the tightness of action screws, scope mount screws, and the cleanliness of scope lenses before each match. The checklist for checks and services varies not just from gun to gun but also in frequency.

However, PMCS does not mandate a complete disassembly and cleaning of your gun after every use.

The point I want to emphasize is that the idea of fully cleaning a gun after every shot is unnecessary. This doesn't mean neglecting your firearm; a quick wipe-down with an oily rag after use is a good practice. During high-round-count range sessions, taking a moment to field strip a pistol for a quick check and wipe-down isn't a waste of time. Similarly, after a day of hunting, it's advisable not to toss your rifle in the rack without giving it a once-over, maybe applying some oil or lube.

Performing PMCS after every use and at regular intervals is essential, but the belief that you must thoroughly clean your gun each time you shoot is more superstition than necessity. If you find yourself inclined to do so, I'd recommend avoiding ladders, staying home on Friday the 13th, and refraining from opening umbrellas indoors.

Just kick back in your easy chair, cleaning your guns. It's an all-time thrill, isn't it?
