Do you have some old, tired brass that needs a thorough cleaning — inside and out? Consider using an ultrasonic cleaning machine. When used with the proper solution, a good ultrasonic cleaning machine can quickly remove remove dust, carbon, oil, and powder residue from your cartridge brass. The ultrasonic process will clean the inside of the cases, and even the primer pockets. Tumbling works well too, but for really dirty brass, ultrasonic cleaning may be a wise choice.
Our friend Gavin Gear recently put an RCBS Ultrasonic cleaning machine through its paces using RCBS Ultrasonic Case Cleaning Solution (RCBS #87058). To provide a real challenge, Gavin used some very dull and greasy milsurp brass: “I bought a huge lot of military once-fired 7.52x51mm brass (fired in a machine gun) that I’ve been slowly prepping for my DPMS LR-308B AR-10 style rifle. Some of this brass was fully prepped (sized/de-primed, trimmed, case mouths chamfered, primer pockets reamed) but it was gunked up with lube and looking dingy.”
UltimateReloader.com Case Cleaning Video (7.5 minutes):
Gavin describes the cleaning exercise step-by-step on UltimateReloader.com. Read Gavin’s Cartridge Cleaning Article to learn how he mixed the solution, activated the heater, and cycled the machine for 30 minutes. As you can see in the video above, the results were impressive. If you have never cleaned brass with ultrasound before, you should definitely watch Gavin’s 7.5-minute video — it provides many useful tips and shows the cleaning operation in progress from start to finish.
The RCBS ultrasonic cleaning machine features a large 3-liter capacity, 60 watt transducer, and 100 watt ceramic heater. The RCBS ultrasonic machine can be found under $140.00, and this unit qualifies for RCBS Rebates ($10 off $50 purchase or $50 off $300.00 purchase). RCBS also sells 32 oz. bottles of cleaning concentrate that will make up to 10 gallons of Ultrasonic Solution.

Many shooters prefer to deprime their fired cartridge cases before other operations (such as neck-sizing and full-length sizing). In addition, when cleaning brass with an ultrasonic system, it’s not a bad idea to remove primers first. That way the primer pockets get cleaned during the ultrasonic process.
To deprime cases before sizing or cleaning you can use a Depriming Die (aka “decapping die”). This pushes out the spent primer without changing the neck or body of a case. Such decapping dies work fine, but they do require the use of a press.
New Handheld Primer Removal Tool From Frankford Arsenal
Here’s a new tool that allows you to deprime cartridge cases without a press. This new hand-tool from Frankford Arsenal will deprime (and capture primers) conveniently. You can deprime your cases while watching TV or relaxing in your favorite chair.
This handy depriming tool is very versatile. With a universal, cylinder-style cartridge-holder, the tool can deprime a wide variety of cartridge types from .20 caliber up to .338 caliber. Spent primers are captured in a removable spent primer catch tube. With die-cast metal construction, this tool should last through many thousands of depriming cycles. MSRP is $54.99.
Will This Tool Work with Small Flash Hole Brass?
This new depriming tool will be introduced at SHOT Show in January 2015. We have not been able to measure the decapping shaft diameter, so we do not know whether this hand tool will work with small flash-holes found on Lapua benchrest brass (such as 220 Russian and 6mmBR). We’ll try to answer that question at SHOT Show. This tool is so new the specs are not yet listed on Frankford Arsenal’s website.

If you’ve never tried ultrasonic cleaning, you should. This process is great for cleaning small gun components, AR innards, carbon-caked suppressors, and even jewelry. Ultrasonic cleaning also transforms old, dirty brass, getting cartridge cases clean inside and out (including the primer pockets). With a big-enough ultrasonic cleaning tub, you can even clean complete AR uppers. One word of caution — we do NOT recommend ultrasonic cleaning for any blued parts or blued firearms.

If you’ve read our feature story on Ultrasonic Cleaning by Jason Baney, you’ve seen the remarkable results that can be achieved with this method. Ultrasonic cleaning has many advantages over traditional tumbling methods of case cleaning. There is no dust or media residue to remove from the brass, and when done right, the cases come out clean and shiney, inside and out, even the primer pockets.
In its Benchtalk Archives, Brownell’s has an excellent article discussing Ultrasonic Case Cleaning. Brownell’s staff compares results, with measured dwell times from 5 to 75 minutes, using both Mpro-7 and HCS 200 cleaning solutions. Tests are performed with once-fired and 5X-fired Tactical 20 (Tac20) cases, as well as once-fired .260 Rem Cases. The article also compares the results from ultrasonic cleaning vs. tumbling in walnut media. Below are Brownell’s results for Tac20 cases with the HCS 200 (non-acidic solution). Go to Brownell’s article for MPro7 results and Rem 260 results.
HCS 200 Cleaning Solution Test
Procedure — Solution was de-gassed for 15 minutes, then 63 Tac20 cases were placed in a single layer, in stainless steel mesh basket. The temperature of the starting solution was 102° F. When the cases were removed the temperature was 110° F.
Once-Fired Tactical Twenty Cases (HCS 200) — Observations 5 minutes: The exterior of the cases are not significantly brighter/cleaner. The primer pockets and case interiors are still dirty. 10 minutes: Exterior of the cases are brighter. 70% of the cases show some degree of cleaning of the primer pockets. Little difference seen inside the case, but case mouths are cleaner. 15 minutes: Case brightness is about the same. Still only 70% of the primer pockets are clean, but a larger portion of each is cleaner. A Q-tip swabbed inside the cases shows that carbon/powder residues are loosening up. 20 minutes: Case exteriors are brightening up. 80-85% of the primer pockets are about 90% clean. The insides of the cases and case mouths are cleaner. 25 minutes: Cases are brighter/cleaner than even new brass. 80-85% of the cases have almost completely clean primer pockets. The inside of the cases are 80-90% clean. 30 minutes: The insides of the cases and case mouths appear to be completely clean. 87% of the primer pockets are virtually 100% clean. 13% of the cases had stubborn primer pocket residue that could not be completely removed. 60 minutes: Eight cases (13%) were placed in the tank for another 30 minutes to try to remove the remaining residue in their primer pockets. Six out of the eight cases were completely clean.
Five-Times Fired Tac20 Cases — Observations 30 minutes: Based on the above observations, I didn’t begin to observe these 5-time fired cases until after 30 minutes: The exterior cases are bright/clean. Brighter than new cases. The primer pockets on 75% of the cases are 75% clean. The remaining cases had primer pockets that were only 25% clean. The inside of the cases appear to be clean. 65 minutes: 25% of the primer pockets were 95% clean, 25% of the primer pockets were 90% clean, 25% of the primer pockets were 85% clean; and 25% were 80% clean. 75 minutes: 75% of the primer pockets were 90% clean.
How Does Ultrasonic Cleaning Work? The Brownell’s article explains: “Ultrasonic cleaning uses high-frequency sound waves (generally between 20-80 kHz) to remove a variety of contaminants from objects immersed in a liquid. The result of these high-frequency sound waves is a process called cavitation. These high frequency bursts of ultrasonic energy produce a three-dimensional wave of alternating positive and negative pressure areas as the sound wave passes through the solution. During negative pressure, microscopic cavitation bubbles form and will continue to grown until they reach resonant size. As the positive sound wave passes, the pressure rises rapidly and implodes these tiny bubbles. Before these minuscule bubbles implode they store a tremendous amount of energy. These bubbles can be as hot as 10,000 degrees and have as much as 50,000 lbs per square inch of pressure. This sounds alarming, but you have to remember that these bubbles are microscopic in nature and pose no harm to anything, unless you are a carbon /powder residue deposit on a cartridge case!
When this cavitation bubble implodes near your brass case, it transforms the bubble into a jet about 1/10th of its size. This jet of energy can travel as fast as 400 km/hour. At 43 kHz, as is the frequency for our L & R HCS 200 ultrasonic cleaner, this is happening 43,000 times per second. This micro-burst of extreme energy is responsible for removing contaminants from the surface of your cartridge brass. Ultrasonic cleaning can reach into crevices and inaccessible areas and remove surface debris that can’t be cleaned by any other process.”
Lyman has introduced two new Turbo®Sonic Ultrasonic Cleaning units, a large 6.3-quart model TS-6000 and a smaller 23.6 oz. model TS-700. Along with the original mid-sized TS-2500 model introduced in 2011, Lyman now offers a full line-up of three (3) ultrasonic cleaning units: large, medium, and small. By most reports the TS-2500 worked well, so we expect the new TS-6000 and TS-700 will also handle ultrasonic cleaning duties well.
TS-6000
The large Model TS-6000 processes up to 1300 9mm cases or four handgun frames in less than 15 minutes (when the built-in heater is used). This workhorse is powered by two industrial-grade transducers and has an integral drain and hose for easy solution changes. The unit’s two-color LED display panel controls five different timed cleaning cycles.
TS-700
The small-footprint Model TS-700 fits in tight spaces. This unheated model handles up to 100 9mm cartridge cases. The compact TS-700 can also clean parts such as dies, muzzle brakes, and mould blocks. Note: Lyman recommends using its Steel & Stainless Steel Solution for dies and other steel components. The TS-700 features oscillation circuitry and five (5) timed cleaning cycles.
TS-2500
The mid-sized TS-2500 model, with heated tank, shown below, process up to 900 9mm cases per cleaning cycle. Introduced in 2011, this product has been widely adopted by hand-loaders. The TS-2500 will clean cases inside and out, including primer pockets, in less than 15 minutes.
Lyman TS-6000 and TS-2500 Units Can Heat Solution for Faster Cleaning
Ultrasonic cleaning machines employ ultrasonic cavitation to gently lift and dissolve carbon, dirt, lubricants, and other residues left on fired cases and small metal parts. Lyman’s TS-6000 and TS-2500 TurboSonic cleaning units feature tank heaters to warm the cleaning solution. Because ultrasonic cavitation works faster and better with a warm solution, Lyman claims its machines’ built-in heaters will speed up your cleaning job, by cutting processing time.
Lyman Cleaning Solutions (Three Types) — Lyman now offers its Brass Cleaning Solution and Steel & Stainless Steel Cleaning Solutions in 4 oz., 16 oz. and 32 oz. sized bottles. For even more versatility a new 16 oz. Jewelry Solution is available. For more information visit www.lymanproducts.com.

Darrell has cleaned and annealed cases for shooters from across the country. Here are recent testimonials (this Editor reviewed all the original emails so I can confirm these are real):
“Your services were good with a quick turn-around time. Quality of the case annealing looked great[.]” — Tom, in Alaska
“The [300 Win Ackley] batch you did for me came back looking great.” — Chuck, in Arizona
“Since I started using Lapua brass, I’ve gotten gotten enough reloads out of them to notice that the necks were no longer sealing as well as I’d like. A friend suggested annealing them. I remembered seeing DJ’s ad on AccurateShooter.com and thought I’d give him a try. Not only did my [.308 brass] come back sorted exactly as I had sent them out, all had been so thoroughly cleaned that I realized I had been leaving lube on them after forming. DJ had taken the time to enclose a note cautioning me to brush the inside case necks and do a full-length resize for the first loading. And all 200 cases were back in my hands in DAYS, not weeks! Great service, great price, great follow up.” — Jim, in Alabama

With top-quality cartridge brass approaching $1.00 per case, it’s more important than ever to get maximum life from your match brass. Annealing can extend the useful life of your brass, and ultrasonic cleaning allows you to eliminate carbon build-up inside cases that have been fired numerous times. You can certainly do annealing and ultrasonic cleaning yourself, but to get the best (and most consistent) results, you’ll need to invest in quality equipment and spend a good deal of time and effort learning how to use it properly. Likewise, turning case necks requires expensive tools, and it takes time and practice before you’ll get perfectly-turned necks.
DJs Brass Offers Annealing, Cleaning, and Neck-Turning
If you don’t have the resources to purchase annealing and ultrasonic cleaning machines, or if you don’t have the time to neck-turn hundreds of cases — don’t fret, there is an affordable option. DJsBrass.com, run by benchrest shooter Darrell Jones, offers annealing, ultrasonic cleaning, neck-turning, and complete brass prep services (including OAL trimming) at very reasonable rates. Darrell will anneal 100 cases for $15, and he’ll neck-turn your cases (any caliber), starting at $30.00 per hundred. Even if you’re a skilled neck-turner, if you just acquired a new caliber, it might make sense to send the work to Darrell, instead of purchasing new expander mandrels and turning arbors.
False-Shoulder Forming for Wildcats
Do you shoot an “improved” short-necked wildcat like the 6mm Dasher? Want your fire-forming to go without a hitch? Darrell can take your parent brass and create a false shoulder so you get a good crush fit in the chamber. If you’re running a tight-necked chamber he can create a false shoulder AND turn the top half of the neck to fit your chamber.
Video Shows Annealing Process
In the video below, Darrell explains the wide variety of brass restoration services he offers. Darrell says he can “bring your brass back to life” and we have found that to be true. We had some 6mmBR brass with no-turn necks that started to lose their “competitive edge” after just 7-8 loadings. The neck tension had become inconsistent from case to case, and bullet seating force (measured with a gauge-equipped K&M arbor press) varied widely. We were seeing unexplained flyers, and ES had nearly doubled compared to when the brass was fresh. Annealing the cases really made a difference. The neck tension was much more consistent and bullets seated more uniformly with less “spiking” of seating force. Paying $15 for annealing is a lot cheaper than buying a new box of brass for $80.00 or more!

We talked recently with our friend Darrell Jones, a talented benchrest shooter from Tennessee, who operates a brass processing business, DJ’s Brass Restoration Service. Darrell ultrasonically cleans old cartridge brass then carefully anneals each case, using temp-sensitive lacquers to ensure the brass is neither over-annealed or under-annealed. As far as we know, DJ’s Brass Restoration Service is the ONLY business in the country offering combined ultrasonic cleaning and annealing. And now Darrell can process your brass with even great efficiency.
Darrell told us he has just received his new, automated dual-torch, carousel annealing machine from Bench-Source. This microprocessor-controlled unit may be the most advanced bench-top annealing machine ever created. Two torches are used to provide intersecting flames for uniform heating. The micro-processor precisely controls the heating time, and a special motor spins each case around its axis while in the heating position. This ensures that the neck and shoulder are annealed evenly.
Combined Ultrasonic Cleaning and Case Annealing
If you have “tired” brass with inconsistent neck tension from case to case, give Darrell a call. His cleaning/annealing process will extend the useful life of your brass, and his service is quite affordable. Darrell’s Basic Service starts at $20.00 per hundred cases — and that includes ultrasonic cleaning AND annealing. (Flat rate USPS shipping is extra.) Note: very large cases (such as the .338 Lapua) or damaged, dented cases may cost more.
In addition to the Basic Service, Darrell offers a 4-Step Full Service starting at $25.00 per hundred cases (plus shipping). Darrell’s Full Service brass restoration includes: Uniforming primer pockets; Chamfering Case Mouths; Ultra Cleaning and polishing; Annealing case necks.
Ultrasonic Muzzle Brake Cleaning
In addition to cleaning and annealing cartridge brass, Darrell offers Ultrasonic Cleaning for muzzle brakes. This removes carbon buildup to restore critical bullet clearance requirements. The price is $15.00 per brake (plus shipping).
For more information, visit DJsBrass.com, or call Darrell at (901) 826-1503. IMPORTANT: Contact Darrell for shipping instructions BEFORE sending any brass for processing. ALL BRASS MUST BE DE-PRIMED before you send it.

Forum Member Dave B., aka “Gunamonth”, is a chemist/physicist with decades of experience working with the ultrasound process. He has achieved great results cleaning cases via ultrasound. Dave tried a variety of solutions and he favors a mix of water and Citranox®. This achieved the best results, and did not require a separate neutralizing step if you rinse the cases thoroughly after. Citranox, mixed 1:75 or 1:100 with water (distilled H20 is best), is inexpensive to use. Phospate-free Citranox® contains a blend of organic acids, anionic and non-ionic surfactants and alkanolamines. For more information on using Citranox®, check out THIS FORUM THREAD.
Dave notes: “I had a lot of communication with the technical VP of Alconox about trying to clean fired cases with an ultrasonic unit. He sent me a copy of his ultrasonic cleaning manual and recommended a product called Citranox®. So far I’ve been very impressed. With once- or twice-fired brass they clean up very quickly. The worst cases I tried were 6 Dashers that had been fired ten times with Varget and never cleaned. The worst fouling was in the bottom of the case around the flash hole. They took longer and I used a more concentrated cleaning solution but they did come out clean. The price is reasonable. I paid $35 a gallon and for once- or twice-fired cases I dilute the cleaner 100 to 1. There is much less chemical reaction with the brass than there is with vinegar. No weird colors, just shiny bright. I even used it with hot water, which speeds up the cleaning process. No need to neutralize. Just rinse in running water and they’re squeaky clean. The cleaner is mostly detergents with a little citric acid. Even at a 1:75 ratio my $35 worth of cleaner will make 75 gallons of solution. It doesn’t seem to be reusable but 75 gallons is a whole lot of solution when I only use about two cups at a time.”
The price has gone up a bit since Dave acquired his Citranox, but Amazon.com sells Citranox for $40.00 per gallon, or you can buy a gallon of Citranox from LabSafety Supply for $46.40.

Hornady’s new Lock-N-Load® Magnum Sonic Cleaner™, with a $317.08 MSRP, provides triple the size and twice the power of the original Lock-N-Load® Sonic Cleaner™.
Dual Transducers for Faster Cleaning
Forum Member Dave B., aka “Gunamonth”, is a chemist/physicist with decades of experience working with the ultrasound process. He has achieved great results cleaning cases via ultrasound. Dave tried a variety of solutions and he favors a mix of water and Citranox®. This achieved the best results, and did not require a separate neutralizing step if you rinse the cases thoroughly after. Citranox, mixed 1:75 or 1:100 with water (distilled H20 is best), is inexpensive to use. Phospate-free Citranox® contains a blend of organic acids, anionic and non-ionic surfactants and alkanolamines. For more information on using Citranox®, check out
