iSonic CSBC001 Ultrasonic Brass Cleaning Solution Super Concentrate, 1Qt Bottle

Following the directions printing on the bottle, after 15 minutes in the ultrasonic cleaner, the 45acp casings looked new - there was no carbon or primer burns either inside the brass or in the primer pockets. Afterwards, the washing with clean water was straightforward without complications. I was so impressed with this product's results I decided to re-clean casings that had been "cleaned" with a different manufacturer's product. The results were startling. Using the recommended 1:40 ratio, the iSonic CSBC001 made the already cleaned brass significantly cleaner-brighter When finished, the solution in the ultrasonic tank went from clear to murky - and this, I repeat, was after cleaning brass casings that had been previously cleaned with a different brass cleaning solution.. This product deserves 6 stars and I'm definitely re-ordering iSonic CSBC001.

Wow for 9mm brass cartridge case cleaning. My 9mm brass looks like new! Clean inside, outside and even the primer pocket is shinny. Used directions on bottle: 40:1 mixture, rinsed cartridge immediately after cleaning in a HF ultrasonic cleaner. I also rinsed the ultrasonic cleaner and wiped dry with a towel. 2 ½ cups of tap water and 1 ½ tablespoons of this CSBC001 solution which just barely went over the minimum mark in my cleaner. 3 - 480 second cycles later I had over 75 perfectly cleaned 9mm brass. I did warm the solution up to around 125-130 degrees in my microwave and then used the heater function on my HF cleaner off and on to keep temperature in that range during the 3 cycles. Used a HF laser temperature measurer to check temperature. Perhaps next time I will poor the solution out after only one cycle and see how they look. Kind of hard to pull the HF short basket out of hot water, so poured the solution out of the cleaner. Very impressed with this solution. I first tried tap water and dawn dish soap and was not happy with the results. Will buy more of this when I run out.

I purchased the iSonic Ultrasonic Cleaner Model P4820 along with Ultrasonic Cleaning Solution for Brass Cases. The P4820 comfortably held 330 (45 ACP) brass. I also cleaned about 500 (380) brass and the contained filled up to only about half. I heated the water first and used one capful of cleaning solution. I ran it through one 480 second cycle. The cases came out very clean. After this, I ran them through the tumbler for about 15 minutes and the looked brand new. Prior to the iSonic, I would have to run the cases through the tumbler for about 6-8 hours to achieve similar results. The iSonic proved to be a great time saver. I must also mention that the seller provides excellent customer service. Upon request, They even emailed me additional tips and techniques on brass cleaning.

This solution worked better than I expected. Ran it in the ultra sonic cleaner for about 25 mins and I’d say it took off at least 98% of dirt and powder residue. Still a little in some of the primer pockets but better than expected.

Used in our supersonic claner and it worked as it says it does. Brass shells were nice and shiny when we ran it for 15 min.

I cleaned my grandfather clock mechanism and it worked great. I do not have a large ultrasonic cleaner so I inverted my four inch vibrating sander and clamped into a vice. I set a medium size tub on the sander with a little over two gallons of water and a cup of cleaner and let it run for about 25 minutes. The brass mechanism came out shiny and clean.

DO NOT USE FOR BRASS MUSICAL INSTRUMENTS!!! It will strip the inside tubing of a slide down to the raw red brass. It will not harm the outside lacquer or finish, but when you pull the slide out it will not be gold or silver but more of that raw brass look. I would recommend a "double boil" method if you are using an ultra-sonic cleaner to clean your brass musical instrument. Get a air/water tight container that the slides/valves/etc. will fit into and the jar that will fit in your cleaner. Put water and dawn dish soap in the jar with the slides/valves, put the lid on, and then submerge the sealed jar into the water only filler ultrasonic cleaner. *Reference to the pictures: The mouthpiece was only two years old and completely silver before I put it in with the chemical and it turned it that "burnt metal/gold" look. You can see the red on the outside of one of the slides, and you can see I tried to show that the inside of a tuning slide it is completely red, stripped down to the raw brass. I am sure this works great for car parts or metal things that do not need to be "pretty" and are very dirty, but this will not work for instruments sadly.

Ensure that you use the product at room temp if using with a silver plated brass instrument. Warm water can damage the finish.
