4 Best Ultrasonic Gun Cleaners in 2026
The best ultrasonic gun cleaner can turn one of the most tedious parts of firearm maintenance into a much simpler job. Instead of picking carbon out of small recesses with a brush, patch, and solvent, you can put properly disassembled parts into a heated ultrasonic tank and let cavitation do the hard-to-reach cleaning. The real differences between machines, though, come down to tank capacity, heating, cleaning time, basket design, and how well the machine fits the amount of gun parts or brass you actually clean.
I compared four options with those factors in mind, from compact benchtop machines to a much larger RCBS unit designed for high-volume case cleaning. The short version: Hornady’s Lock-N-Load Sonic Cleaner II is the best balance for most people, Lyman’s Turbo Sonic 2500 is the budget choice, and RCBS’s Ultrasonic Case Cleaner 2 is the one to buy when capacity matters more than price.
Quick Answer: The Best Ultrasonic Gun Cleaners
| Ultrasonic Cleaner | Best For | Tank Capacity | Key Advantage |
|---|---|---|---|
| Hornady Lock-N-Load Sonic Cleaner II | Best overall | 2 liters | Excellent balance of cleaning performance, controls, and size |
| Lyman Turbo Sonic 2500 | Best budget option | 2.5 liters | More capacity for the money |
| RCBS Ultrasonic Case Cleaner 2 | Best for high volume | 6.3 quarts / 6 liters | Much larger tank and 30-minute continuous timer |
| Infante Ultrasonic Gun Cleaner | Dedicated firearm cleaning | Varies by model | Purpose-built firearm cleaning systems |
The first three are the most directly comparable machines for a home bench or reloading setup. Infante takes a different approach with dedicated firearm-cleaning equipment rather than a general-purpose benchtop cleaner.
What Is an Ultrasonic Gun Cleaner?
An ultrasonic cleaner uses high-frequency sound waves transmitted through a liquid solution. Those waves create cavitation bubbles that rapidly form and collapse against immersed surfaces, helping loosen carbon, grease, dirt, oil, and other contaminants from areas a brush cannot easily reach.
That’s the reason ultrasonic cleaning makes so much sense for small firearm components. Slides, bolts, trigger components, and other intricate parts can have recesses, channels, and pockets where conventional brushing becomes slow and frustrating.
The machine itself isn’t the whole equation, though. The cleaning solution, temperature, cycle time, and the material being cleaned all matter. Lyman, for example, specifically warns that the correct solution is important because using an inappropriate solution can damage the item being cleaned.
And an ultrasonic cleaner isn’t a magic replacement for every part of firearm maintenance. It cleans components; it doesn’t automatically inspect them, lubricate them, or put the firearm back together correctly.
Hornady Lock-N-Load Sonic Cleaner II — Best Overall
For most shooters and reloaders, the Hornady Lock-N-Load Sonic Cleaner II is the easiest machine to recommend because it strikes a useful middle ground. It isn’t the biggest cleaner here, but you don’t need a six-liter tank to clean the components of one handgun or a normal batch of smaller parts.
The advantage becomes clearer when you look at how the machine is used. Hornady designed the cleaner around case and parts cleaning, and its Sonic Cleaner line is particularly well suited to people who want a relatively straightforward benchtop machine rather than a professional-sized system.
The original testing behind this article also found the Hornady particularly easy to live with. Its timer can be adjusted in five-minute increments and then fine-tuned with one-minute adjustments, which is much more useful than it sounds when you’re trying to find the right cycle for a particular load of dirty parts.
It also performed strongly on both brass and fully disassembled firearm components in the supplied testing. That makes it the better choice if you want one machine that can handle both sides of the job without taking over the workbench.
Best for: Most shooters, reloaders, and home firearm-maintenance setups.
Main advantage: Strong balance of cleaning performance, controls, and footprint.
Main drawback: The 2-liter tank gives you less room than the Lyman or RCBS machines.
Lyman Turbo Sonic 2500 — Best Budget Ultrasonic Gun Cleaner
The Lyman Turbo Sonic 2500 is the one I’d look at first if you’re interested in ultrasonic cleaning but don’t want to spend heavily on a machine you’ll only use occasionally.
Its 2.5-liter tank gives it a little more capacity than the Hornady, while Lyman’s current specifications list a heated tank, plastic basket, and capacity for up to 900 9mm cases, 400 .223 cases, or 250 .30-06 cases. Lyman says the machine can clean cases inside and out, including primer pockets.
That’s useful information because tank capacity isn’t just a specification on the box. If you’re cleaning a handful of firearm parts, 2.5 liters is plenty. If you’re processing a large amount of brass, that extra space can mean fewer cycles.
The original article’s hands-on notes are worth keeping here, too. The Turbo Sonic 2500 produced strong cleaning results, but the tank took roughly 40 minutes to reach operating temperature in the testing described. Once hot, however, the heated solution helped the machine do its job effectively.
At 6.5 pounds, it’s also reasonably easy to store when you’re finished with it rather than leaving another piece of equipment permanently occupying your bench.
Best for: Budget-conscious shooters and reloaders.
Main advantage: Good capacity and useful cleaning performance without moving into premium-machine pricing.
Main drawback: Initial heat-up can take a while.
RCBS Ultrasonic Case Cleaner 2 — Best for High-Volume Cleaning
If the first question you ask is, “How much can I clean at once?”, the RCBS Ultrasonic Case Cleaner 2 is the obvious step up.
Its 6.3-quart, or approximately 6-liter, tank is nearly twice the capacity of the smaller machines. RCBS specifically positions the cleaner around brass case preparation, and the current model includes a stainless-steel parts basket, a smaller stainless-steel parts tub, an LCD display, and a timer capable of up to 30 minutes of continuous cleaning.
That capacity changes the calculation for someone who reloads in volume. A larger tank isn’t automatically a better cleaner, but it can be a much better workflow tool when you’re repeatedly processing large batches.
The RCBS also has another practical advantage: the smaller parts tub helps keep little components contained rather than allowing them to disappear into the bottom of a large tank.
The tradeoff is obvious. This is a considerably larger and more expensive machine than the Lyman or Hornady. RCBS currently lists the Ultrasonic Case Cleaner 2 at roughly $445–$475 depending on configuration, so it makes considerably more sense for a serious reloader or high-volume user than someone cleaning a few firearm components a couple of times a year.
Best for: High-volume reloaders, gunsmithing benches, and users cleaning large batches.
Main advantage: 6.3-quart capacity and a 30-minute continuous timer.
Main drawback: Much higher price and larger bench footprint.
Infante Ultrasonic Gun Cleaners — Best Dedicated Firearm Option
Infante takes a different approach from the conventional benchtop machines above. Its ultrasonic systems are specifically marketed around firearm cleaning rather than primarily around brass case preparation.
The company’s current firearm systems emphasize tank size, ultrasonic power, baskets, cleaning solutions, and—in some systems—ultrasonic lubrication as part of the overall process. Infante also markets its equipment toward professional users such as gunsmiths and serious firearm owners.
That makes this category worth considering if firearm parts are the main reason you’re buying an ultrasonic cleaner and you expect to use it frequently.
The downside is that a dedicated professional system is a different proposition from buying a $100–$200 benchtop cleaner. For the average home user, the extra equipment and cost may not provide enough additional value.
Best for: Professional or high-frequency firearm cleaning.
Main advantage: Purpose-built around firearm parts rather than general household cleaning.
Main drawback: More specialized and potentially much more expensive than a conventional benchtop ultrasonic cleaner.
What Matters When Choosing an Ultrasonic Cleaner for Gun Parts?
Tank size gets most of the attention, but it isn’t the only specification that matters.
Tank Capacity
For occasional handgun-part cleaning, a roughly 2- to 3-liter machine is generally enough. A larger tank becomes useful when you’re cleaning rifle components, multiple firearms’ parts, or substantial batches of brass.
The important point is to buy for the parts you actually clean. A huge tank sitting half empty doesn’t automatically produce better results.
For high-volume brass cleaning, however, the difference is significant. The RCBS’s 6.3-quart capacity is specifically intended to let users process substantially more cases in one cycle.
Heating
Heat can make ultrasonic cleaning more effective and is a useful feature for firearm and brass cleaning.
Both the Lyman and RCBS machines use heated tanks, while the original testing of the Lyman and Hornady machines found that reaching operating temperature took roughly 40 minutes from a cold start.
That means you should distinguish between cleaning time and total workflow time. A machine advertised with a five- or ten-minute cleaning cycle may still require substantially longer before you’re ready to run that first load.
Cleaning Time and Controls
Simple controls are underrated.
If you frequently clean different types of parts, adjustable cycle times let you avoid treating every load the same way. The Hornady’s easy-to-adjust timer is one reason it remains attractive despite its smaller tank, while the RCBS provides up to 30 minutes of continuous cleaning.
Basket Design
Use the supplied basket rather than dropping components directly onto the bottom of the tank.
A basket keeps parts separated from the tank surface and makes removing small components much easier. The RCBS goes a step further by including both a larger parts basket and a smaller parts tub.
Cleaning Solution
This may be the most overlooked part of the setup.
Don’t assume that any household cleaner is appropriate simply because it works in an ultrasonic machine. Lyman’s instructions specifically emphasize choosing the correct solution for the material being cleaned.
A solution suitable for brass isn’t automatically the right choice for every firearm component. Materials, coatings, finishes, and existing lubrication all need to be considered.
Ultrasonic Cleaning vs. Manual Gun Cleaning
An ultrasonic cleaner is best viewed as a complement to normal firearm maintenance, not a complete replacement.
The machine is particularly useful for removing contaminants from intricate parts and hard-to-reach areas. Manual cleaning is still useful for inspection, bore maintenance, wiping surfaces, applying lubricant, and dealing with contamination that needs direct mechanical attention.
That’s also why a traditional cleaning kit remains useful after the ultrasonic cycle.
Hoppe’s, for example, still sells universal cleaning kits containing rods, brushes, patches, solvent, and lubricant. Its current Universal Cleaning Accessory Kit is designed to cover multiple rifle, handgun, and shotgun calibers.
Think of the ultrasonic cleaner as the deep-cleaning stage, not the entire maintenance routine.
Do You Need an Ultrasonic Cleaner for Brass Cases?
Not necessarily.
Ultrasonic cleaning can clean brass inside and out and reach primer-pocket areas, which is one of its biggest advantages. Lyman specifically advertises that capability on the Turbo Sonic 2500.
But reloaders have other options, particularly dry tumbling and wet tumbling. The better choice depends on how much brass you’re processing, how clean you want the finished cases, and how much drying and handling you’re willing to do.
If brass is your only reason for buying an ultrasonic machine, compare the workflow rather than assuming ultrasonic cleaning is automatically superior.
If you’re buying one machine to clean both brass and firearm components, the equation becomes more attractive.
Which Ultrasonic Gun Cleaner Should You Buy?
Buy the Hornady Lock-N-Load Sonic Cleaner II if you want the best balance. Its compact size, straightforward controls, and strong cleaning performance make it the easiest recommendation for most home users.
Buy the Lyman Turbo Sonic 2500 if price matters most. You get a heated 2.5-liter machine with useful brass capacity without moving into the cost of the larger RCBS.
Buy the RCBS Ultrasonic Case Cleaner 2 if you clean in volume. The 6.3-quart tank is the feature that matters most here, especially for reloaders processing substantial batches of brass.
Consider Infante if firearm cleaning is a serious, frequent operation. Its dedicated systems make more sense for professional or high-frequency use than for someone who occasionally cleans a handgun.
Frequently Asked Questions
What is the best ultrasonic gun cleaner?
For most home users, the Hornady Lock-N-Load Sonic Cleaner II is the strongest overall choice because it balances cleaning performance, controls, capacity, and size. The Lyman Turbo Sonic 2500 is a better budget option, while the RCBS Ultrasonic Case Cleaner 2 makes more sense for high-volume cleaning.
What size ultrasonic cleaner do I need for gun parts?
A roughly 2- to 3-liter machine is enough for many handgun parts and smaller firearm components. Move toward 4 to 6 liters if you regularly clean larger parts, multiple sets of components, or significant quantities of brass. Larger machines can reduce the number of cycles required.
Can you clean gun parts in an ultrasonic cleaner?
Yes, but the parts should be suitable for ultrasonic cleaning and the solution must be compatible with their materials and finishes. Lyman specifically recommends confirming that the correct solution is being used for items other than the machine’s intended case and steel-part applications.
Can an ultrasonic cleaner replace a gun cleaning kit?
No. An ultrasonic cleaner can handle deep cleaning of suitable disassembled components, but a conventional cleaning kit is still useful for bore cleaning, lubrication, wiping, inspection, and final maintenance.
Is an ultrasonic cleaner good for brass cases?
Yes. Ultrasonic cleaners can clean brass cases internally and externally and can reach areas such as primer pockets. The Lyman Turbo Sonic 2500, for example, is specifically designed for case cleaning and lists substantial case capacity.
Does a bigger ultrasonic tank clean better?
Not necessarily. Tank size primarily determines how much you can clean in one cycle. Cleaning performance also depends on the machine’s ultrasonic system, temperature, solution, load arrangement, and cycle settings. A larger tank is most valuable when you actually need the additional capacity.
Final Verdict
The Hornady Lock-N-Load Sonic Cleaner II remains the best all-around choice for most people who want an ultrasonic gun cleaner without turning their workbench into a dedicated cleaning station. It has enough capacity for normal firearm-part and brass cleaning, straightforward controls, and the kind of performance that makes ultrasonic cleaning genuinely useful rather than merely interesting.
The Lyman Turbo Sonic 2500 is the better starting point if you want to spend less, while its 2.5-liter capacity makes it surprisingly practical for brass as well. The RCBS Ultrasonic Case Cleaner 2 is the obvious upgrade when volume is the deciding factor; its 6.3-quart tank and 30-minute timer are difficult to justify for occasional use but make much more sense in a serious reloading setup.
Whichever machine you choose, don’t overlook the solution and the rest of the cleaning process. Ultrasonic cleaning can remove the grime you can’t easily reach by hand, but inspection, drying, lubrication, and proper reassembly are still part of maintaining the firearm.
