Wet-Tumbling Cartridge Brass — Tips for Great Results

Cartridge brass case tumbler thumblers wet brass stainless media lapua cleaning

Ace tactical shooter and gunsmith Jim See of Elite Accuracy LLC recently tested a Frankford Arsenal rotary brass tumbler. Like the older Thumbler’s Tumblers, this can tumble your cases in a liquid solution. The wet-tumbling process worked very well Jim reports. Posting on Facebook, Jim noted: “I was super impressed with the Frankford Arsenal rotary tumbler and cleaning packs they sent me. I ran 350 pieces of brass for one hour. They now look great.” Jim appreciated not having to deal with dry tumbling media, such as crushed walnut shells. Dry media produces dust and can leave residues or clog flash-holes.

Interestingly, Jim recommends you try wet-tumbling WITHOUT using stainless media. At least give it a try. Tumbling without media simplifies the process and you don’t have to worry about pins stuck in flash-holes or case-necks*. Jim reports: “Stainless steel pins come with the Frankford kit, but mine hit the trash right out of the box. There is no need to clean the inside of your cases 100% and that’s all the pins add to the equation. The brass bumping brass with hot water and Frankford’s liquid cleaner works great all by itself.” One wag stated: “That’s great to hear. Stainless steel pins are a PITA.”

Other Facebook posters concurred with Jim’s evaluation of the Frankford Arsenal Rotary Tumbler:

“I’ve had one for a couple years, and it works well. I usually run about 250-300 Dasher cases at once in it. But I use the pins because I’m OCD about clean brass.” — David W.

“I’ve had one for a year and a half and it definitely works with or without pins.” — Luke C.

“I got one about six months ago and have yet to use any SS media. I just use some dawn, distilled water, and Lemi Shine®. Turns nasty 5.56 range brass bright and shiny.” — Brian D.

“I don’t use the pins either and use a combination of Dawn soap and Lemi Shine.” — Jon N.G.

This video shows how to assemble and operate the Frankford rotary tumbler. NOTE That Jim See does NOT feel that it is necessary to use stainless media.

How to Dry Your Brass — Hair Dryer Vs. Machine

The downside of wet tumbling is that you end up with a pile of wet brass at the end of the cleaning cycle. There are many ways to dry brass, from drying in the sun to using a kitchen oven (be careful not to “overcook” your brass). One Facebook poster asked Jim: “What is your drying method for wet brass, and how long does it take?”

Jim See replied: “To start I just drain off the dirty water, and rinse the brass with clean hot water. Then I roll the brass on a towel for 30 seconds and put the brass in a one-gallon bucket. Next I insert a hair dryer in the bucket (with the brass) and let it run for about 5 minutes. With this procedure, the drying process for me is done in less than 10 minutes.”

Jack Lanhart has another method: “I use a food dehydrator. It takes 30 to 45 minutes.”

For those who don’t want to mess with towels and hair dryers, Frankford Arsenal offers a matching Platinum Series Case Dryer that simplifies the process of drying brass. Lyman also makes an excellent Cyclone Case Dryer. Both drying machines cost about $60.00 and both have multiple levels so you can separate different types of cartridge brass. Lyman states that “The forced heated air circulation of the Cyclone will dry your brass inside and out within an hour or two, with no unsightly water spots.” The Lyman dryer can also be used for ultrasonically-cleaned gun parts.

Sinclair Product Report: Thumler’s Tumbler with Stainless Media

We know that many of our readers are now tumbling their brass in liquid media rather than dry media such as corn-cob or walnut shells. When done with STM stainless tumbling media (small ss pins), this system really does work, producing brass that is clean “inside and out”. The only down-side to wet tumbling is that sometimes the inside of the caseneck gets so “squeaky clean” that bullets take more effort to seat. This can be remedied with the use of a dry lube inside the necks. When cleaning with stainless tumbling media you’ll need a quality tumbler that is water-tight. The wet-tumbler of choice is the Model B Thumler’s Tumbler. Featuring a bright-red, side-loading drum, the Model B Thumler’s Tumbler is reliable and built to last.

A while back, Bill Gravatt, then President of Sinclair Int’l, had a chance to evaluate the Thumler’s Tumbler and the wet-cleaning process for cartridge brass. Bill came away a believer: “I wanted to share with you my experience using the Thumler’s Tumbler and stainless steel pin media to clean brass.

New Rotary Tumbler for Wet-Cleaning Cartridge Brass

More and more shooters are “wet-tumbling” their brass (in liquid) with reusable polishing media, rather than using dry media in a vibratory tumbler. The “wet-cleaning” method works best with a rotary tumbler fitted with a water-tight, horizontal drum to hold your brass, cleaning solution, and stainless, pin-type media. The rotary tumbler of choice has been the Thumler’s Tumbler Model B Heavy-Duty. That is a great, sturdy machine, but now you have a more affordable option.

Frankford Arsenal Platinum Series wet liquid horizontal rotary tumbler

Frankford Arsenal has introduced a “Platinum Series” rotary tumbler designed to clean cartridge brass with liquid and stainless media.The watertight, polymer drum rides on four rollers which rotate the drum around its horizontal axis. Two filters are provided so you can quickly separate your brass and media. A built-in timer allows you to set tumbling sessions up to three hours. Frankford Arsenal says its new product will clean up to 1000 cases of .223 Rem brass. That’s impressive capacity.

The Frankford Arsenal rotary tumbler is sold by major retailers including Grafs.com and Cabelas. You’ll find the best prices online.

Forum Member Tests STM System
Our reviewer, Forum member Jason Koplin, purchased the STM media and a new Thumler’s Tumbler. He then tested the STM cleaning procedure on his own brass, including some extremely dirty and tarnished “range pick-up” brass. Jason was thoroughly impressed with how well the STM process worked — as you can see from the “before and after” photos below. Brass which looked like it was ready for the scrap heap was restored to “like-new” appearance. The process works equally well on both rifle brass and pistol brass. Jason observed that one surprise benefit of the STM cleaning procedure is a big reduction in noise. Jason said the water-filled rotary tumbler was much quieter than his vibratory tumblers.
