Dawn dish soap & Lemishine?

I know some people are using this mixture in their sonic cleaners to clean their Brass. Can anyone tell me what the ratio would be to mix up a gallon jug. I know you're supposed to use the Lemishine, sparingly. Any help would be appreciated.
 
I use a "LIGHT" shake of lemishine and a drop of Dawn ultra in my 1.2 liter ultrasonic cleaner. So I would go teaspoon of LS and 3-4 drops of Dawn ultra for a gallon of water. Go strong on the LS and pink brass can occur. I use HOT water for cleaning/rinsing.
 
Less Lemishine is better for brass surface erosion. Left in solution for months as a test, Dawn is harmless to brass but a solution high in Lemishine has the effect of a sandblaster on it.
Yes! I found the same thing. I wasn't using much, a 9mm caseful in a Thumler's Tumbler with stainless pins. Pistol brass would drag and squawk on my Dillon's powder funnel. Sizing effort was high. Omitting Lemishine alleviated the problem. Adding some car wash n' wax helped to slick things up. Lemishine does make for blingy brass, but as you say it messes with the surface finish.

I haven't tumbled in a few years, but will do so pretty soon, I have a load of 308 cases I need to clean. I have a Thumblers and had previously quit using the stainless pins as just the brass banging against each other with the Lemishine and Dawn was enough to get 'em spanky clean...I manually clean out the primer pockets with a hand tool.
 
Get some "Brass Juice". Works much better than the home brew mixes.
I second the " Brass Juice " it takes very little and does an excellent job.
I've found too much and it will give it a pink color but dissapears after the first firing, I also use a small amount of dawn.
When using the dawn and Lemishine I find less is better using no more than a teaspoon gets the job done.
 
RCBS tumbler, Gallon tap water, 1 teaspoon Dawn, 1/4 teaspoon Lemishine, run for 45 minutes. Rinse thoroughly (at least a couple of times), Separate the SS pins from the brass, dry the brass and pins. Ready to reload.

I used to use a quarter teaspoon of lemi and dawn. It worked well but now I use Shooter 2 cleaner now when wet tumbling my cases. Works great for BP and smokeless. Not for use on nickel cases though.
 
I can't understand why anyone would want to use a home brew that could cause damage to brass. For the price of true brass polish compound it's hardly worth taking the chance of damage especially since some brass has become quite expensive or even impossible to replace! Vinegar, CLR, Lemishine are acid based and are corrosive to brass.
 
I watch a lot of YouTube videos on guys restoring cars. Apparently the best ultrasonic cleaner out there is Pine-Sol from Walmart. A little bit of Lemmy shine is always a good idea as it not only has a little bit of acid it also has a water softener. But you might try the pine sol straight out of the bottle
