As the last waterfowl hunt of the season wrapped up, I found myself doing what I always do this time of year, breaking down my shotgun for a proper cleaning before it gets put away. It’s a routine I follow with every firearm I own. When opening day rolls back around, I want everything ready to go, not scrambling at the last minute.
The good news? It doesn’t take much. With a handful of tools and a little time, you can protect your investment and avoid headaches down the road.
Start With Disassembly and Inspection
The first step is to disassemble and inspect your firearm. If you struggle to disassemble or as I often see, reassemble, the best tool I can recommend is your phone. Take pictures of your shotgun in the different stages of disassembly.
Laying out the firearm in the order it is disassembled also helps. The manual for the firearm will tell you how far you should disassemble the firearm. A word of warning: do not disassemble further than the owner’s manual recommends. Going beyond what’s recommended can cause more harm than good.
And if you get stuck, there’s almost always a helpful video online that walks through the process step by step.

Problem Areas Most People Miss
Certain parts of a shotgun tend to get overlooked, especially in semi-autos. The recoil spring tube and magazine tube are two big ones.
I once had a friend who was an experienced waterfowler tell me his shotgun was acting sluggish even though he cleaned it. When I got my hands on it, I pulled the recoil pad and poured out a cup of foul, black swamp water from inside the stock. At some point, the gun had taken a dunk, and that trapped moisture led to rust and a barely functioning recoil system.
To prevent that kind of issue, I drilled a small drain hole between the recoil pad and sling stud. It’s a simple fix that can save a lot of trouble.
For carbon buildup on the magazine tube, a green kitchen-style scratch pad works well. It removes grime without damaging the metal.

One mistake I see often is spraying carbon cleaner into the action and then storing the gun upright. That liquid runs down into the action and magazine tube, creating a sticky mess that slows everything down. If you’re using a cleaner like that, lay the shotgun barrel-down on a towel and let gravity do its job.
Don’t Forget the Choke Tubes
Choke tubes have a bad habit of seizing up if neglected. Firearm maintence with choke tubes starts at installation. Before installing them, apply a generous coat of anti-seize to the threads. It makes removal much easier later. This applies even if you don’t plan to swap chokes often. If one is already stuck, it may be time to bring it to a gunsmith rather than risk damaging the barrel.
Use the Right Products
Stick with approved cleaning products. Avoid shortcuts like brake cleaner or other harsh chemicals. They can strip finishes, especially on alloy receivers, and cause more harm than good. Gun cleaning products, like those from Otis Technology, are specifically formulated to break down fouling while also protecting metal surfaces and lubricating moving parts. That is something general cleaners simply aren’t designed to do. When you use the right products, you’re not just cleaning your firearm, you’re preserving its performance, safety, and lifespan.
Lubrication: Less Is More
Once everything is clean, meaning no carbon residue comes off on your fingers, it’s time to lubricate. Focus on the areas where parts make contact and move against each other. A light application is all you need. Over-lubricating can attract dirt and eventually gum things up.

And skip the WD-40. It has its place, but not on firearms. Over time, it can cause more issues than it solves.
When to Call a Gunsmith
If your shotgun needs deeper cleaning, such as in areas like the trigger group, it’s worth considering letting a gunsmith handle it.
For lighter debris like weed seeds or dust, compressed air works well. The low-pressure cans from an office supply store are perfect and won’t send parts flying.
Different Guns, Different Needs
Not all firearms require the same level of attention. Pump guns and over/unders are relatively simple. A quick breakdown and cleaning usually does the job. On pump guns, I always check the magazine follower—many are polymer and can collect dirt or debris that affects feeding.

For over/unders, a soft toothbrush under the extractors will clear out most buildup.
Shotgun bores are typically chrome-lined or otherwise coated, so they stay fairly clean. A bronze or plastic brush is usually enough to remove powder or wad residue.
Rifle Maintenance Basics
Rifles follow similar principles. Semi-auto rifles should be broken down into component groups, cleaned individually, then lubricated at wear points before reassembly. Bolt-action rifles require less work. Most of the focus is on the bore.
I typically clean the bore at the end of the season using a bore guide, a bronze brush, and a cleaning solution. Running patches through until they come out clean is the goal.

Make It a Routine
Firearm maintenance doesn’t have to be complicated. I usually budget about an hour per firearm and set aside an afternoon to get everything done. You might be faster, but the key is consistency. A little time spent now on firearm maintenance beats scrambling the day before the season, and it ensures your gear is ready when it matters most.
