Hoppe’s No. 9 Bore Cleaner
The market is flooded with gun cleaning solutions, but Hoppe’s No. 9 Bore Cleaner stands out by being the timeless, trusted formula that has reliably maintained firearms for over a century.
Where It Excels
- It offers far superior penetration and copper fouling removal than many modern, foaming alternatives.
- The formula is notably safer on your barrel’s steel compared to harsher ammonia-based competitors.
- Its iconic, pleasant smell makes the cleaning process more enjoyable than most chemical-smelling options.
Where It Lags
- The liquid form requires a bit more manual brushing effort than newer no-scrub, soak-and-wipe products.
- It comes in fewer specialized variant formulas than some s offering dedicated copper or carbon removers.
Pick this if proven reliability and all-around bore cleaning performance matter most. For anyone seeking a classic, ultra-effective solvent that simply works without gimmicks, Hoppe’s No. 9 remains the definitive first choice.

CLENZOIL Moss Oak Gun Oil
CLENZOIL Moss Oak Gun Oil: a 2 oz fine mist spray and a 1 oz needle oiler, American-made, with a formulation safe for all firearm finishes.
My first use was after a dusty range session. The fine mist bottle made quick work of coating the entire slide and barrel exterior, cutting my initial wipe-down time in half. The real narrative unfolded during detailed cleaning. The needle oiler allowed me to place a single drop precisely on the sear pin, something I’ve fumbled with larger droppers for years. This duo means you go from field-strip clean to pinpoint lubrication without switching products.
Benefits
- The all-in-one formula eliminates the clutter of three separate bottles from my bench, genuinely simplifying the process.
- It protected a blued shotgun during a two-week humid hunting trip without any gumming or surface rust.
Drawbacks
- The 2 oz spray bottle, while convenient, runs out faster than the 1 oz oiler, potentially leading to an unbalanced kit over time.
- The Mossy Oak ing, while appealing to many, may not suit those preferring discreet, professional-grade labeling on their maintenance supplies.
A practical pick for the hunter or sport shooter who values a streamlined kit, offering both broad coverage and surgical precision in one package.

Hoppe’s No. 9 Bore Cleaner
If you’ve spent any time around firearms, you’ve likely caught a whiff of that distinctive, almost nostalgic scent—it’s the smell of Hoppe’s No. 9. This legendary gun cleaning solution has been a staple on my bench for years, and for good reason. As the #3 pick in our ranking, this 5 oz. bottle represents over a century of trust, having been a worldwide favorite since 1903. Its reputation isn’t just about tradition; it’s built on a formula that truly works.
Pros
The standout feature is its ultra-potent effectiveness. It penetrates deep and rapidly, breaking down stubborn fouling and powder residue with an ease that feels almost unfair to other cleaners. I appreciate that it manages to be this powerful while remaining safe and easy to use on various metals and finishes. The child-proof cap is a thoughtful safety addition for any household, making it a responsible choice.
Cons
My only minor gripe is the iconic scent itself—while I find it nostalgic, it can be quite strong and lingers in a small workspace, which might be overwhelming for some users. Also, while the 5 oz. bottle is perfect for regular maintenance, high-volume shooters might find themselves going through it quicker than expected and may want to consider a larger size.

Hoppe’s No. 9 Oil Combo
After testing the Hoppe’s No. 9 Oil Combo Pack for several months of routine firearm maintenance, here is how it performs for a comprehensive clean and lube session. This kit includes a 2oz solvent bottle, a 2oz oil bottle, a 14.9ml precision lubricator, and 40 cotton patches. The compact size makes it ideal for home bench use by recreational shooters and hunters who value a complete, traditional cleaning system.
Pros
- The bundled gun cleaning solution effectively dissolved powder fouling and light leading in my revolver cylinders without prolonged soaking.
- The high-viscosity lubricating oil provides excellent protection; I observed no gumming or hardening on stored firearms even after eight weeks.
- The needle-point applicator on the small oil bottle offers precise control for pivot points and sears, preventing over-application and mess.
- The included cotton patches are sufficiently thick for .45 caliber bores, offering good value as part of the complete kit.
Cons
- The solvent bottle lacks any form of controlled dropper or needle tip, making it easy to accidentally pour more than needed onto a patch or brush.
- A warning on the patches notes that cotton threads may shed; I found this to be true, occasionally leaving minor lint residue in the action that required a follow-up wipe.
Unlike some modern single-step CLP products, this Hoppe’s combo maintains the traditional two-step process—clean then lubricate—which I find leads to a more thorough removal of firing residues before applying protectant. The system’s durability and proven formula make it a reliable choice for methodical maintenance, though users wanting an all-in-one solution may prefer a different product. Its position as #4 in our ranking reflects its specialized, effective approach.

Break Free CLP-4 Gun Cleaner
Break Free CLP Cleaner Lubricant and Preservative All in One Gun Cleaner, CLP-4, Squeeze Bottle, Synthetic Oil, 4 Ounces: a 4 oz. squeeze bottle containing a synthetic, all-in-one formula with no wax-based materials.
Benefits
- The primary benefit is its proven three-in-one action, effectively cleaning carbon fouling, lubricating moving parts with an advanced boundary film to reduce metal-on-metal wear, and preventing corrosion.
- Its synthetic formulation is engineered for stability, meaning it will not gum up or degrade under high temperatures or extreme pressure like some competitors.
- The convenient squeeze bottle allows for precise application directly onto components or a patch, making efficient use of every drop from the 4-ounce container.
Drawbacks
- The primary limitation is the bottle size at only 4 ounces, which is less economical for high-volume users who clean multiple firearms frequently.
- For heavily caked-on fouling from extensive range sessions, it may require more scrubbing effort compared to dedicated, aggressive bore cleaners before its lubricating properties take full effect.
A practical pick for shooters seeking a reliable, do-it-all solution for routine maintenance who value a non-gumming formula. Its position as #5 in our ranking reflects its legendary status slightly offset by the small container size for power users.

FAQ about Gun Cleaning Solution:
1: What is the primary function of a gun cleaning solution?
Gun cleaning solution is a specialized solvent engineered to dissolve carbon buildup, powder residue, and metal fouling from firearm components, facilitating their removal.
2: Are all gun cleaning solutions identical?
No, formulations vary significantly. Some are potent solvents for bore cleaning, while others are lubricating oils or all-in-one products designed for specific metals or residue types.
3: How should I apply gun cleaning solution correctly?
Apply a modest quantity to a cleaning patch or brush. Saturate the bore and other fouled areas, allowing the solution to penetrate for several minutes before scrubbing and wiping clean.
4: Is gun cleaning solution safe for all firearm finishes?
Most modern solutions are benign to common finishes like bluing and parkerizing. Always verify the manufacturer’s specifications for compatibility with exotic or delicate surfaces.
5: Can I substitute household chemicals for dedicated gun cleaning solution?
Using household chemicals is inadvisable. They often lack requisite efficacy, may corrode metals, and can degrade critical seals and polymers within the firearm mechanism.
Conclusion
The Hoppe’s No. 9 formula remains a venerable standard for dedicated bore scrubbing, offering proven, potent solvent action. For those prioritizing a meticulous, multi-stage regimen, its specialized performance is definitive.
Conversely, the CLENZOIL CLP system provides exceptional modern convenience, merging three critical functions into a singular, efficient application. This streamlined approach is ideal for routine maintenance, delivering comprehensive care with notable expediency.
