Frankford Arsenal Walnut Media Treated and Untreated, 5LB- 18LB, for Ammo Reloading, Shooting Bag Filling, and Case Tumbling

Works well in my tumbler even if they are really dirty just takes a little longer.

very good quality, easy to use

Be sure to keep this stuff in a dry environment (<50% RH) so it does not swell. I'm using a cheap Chinese blast pot around $120 from eBay but these can be had cheaper from Harbor Freight. I adapted the nozzle with a short brass nipple and a 1/4" compression fitting to take 1/4" copper tubing. My compressor is a Makita pancake style compressor with 8.3cuft/min at 120psi. You only need 5-8 second blasts and a vacuum nozzle adapter is recommended. There's someone on eBay selling 3D printed port adapters to attach to your vacuum cleaner. These worked for my vehicle (Mazda Cx-7) but not without some filing down as they don't fit very well. I have added a before and after photo of my cylinder #1 /Valve #1. The third image is after Brakleen washing the port. Be careful to tighten all hose connections and wear appropriated PPE (gloves, face shield) as this stuff at 90 psi will shred your skin. I used a piece of 3/8" taped to my vacuum cleaner nozzle to vac out the remaining walnut shell debris and then Brakleen to spray the ports to finish the job. I used a 50ml syringe with a straw from an old spray bottle to suck out the repeated applications for Brakleen solvent. The valves almost look like new again

There are many types of cleaning media that can be used to clean brass casings, and the discussion over the "Best one" often becomes a discussion similar to the best brand of motor oil. I've used various kinds over the years, and I don't really put too much effort into analyzing the performance. It either gets the brass clean without too much extra mess, or not. This walnut media does a nice job of cleaning, especially if you add some polish to the media. It will get dustier over time, and also will get "dirtier" with use. I use these two factors as indicators for replacement. When it becomes too dusty it is usually because the media has pulverized itself into finer and finer particles. When it starts leaving too much residue on the brass, it's usually an indicator that it is saturated with contaminants and needs to be changed. Added plus - the clear plastic container makes an ideal storage container for your brass! I find it a decent value, and I am able to clean many thousands of casings with it before discarding.

Cleans rifle brass very thoroughly. Small particle size gets inside of cases better than corn cob media. Does not shine the cases as well as corn cob media but creates a very clean look. Somewhat dusty.

Good medium at a good price. Fast shipping.

Did what it said it would do. Husband likes it.

Cleaner works great on brass.
