sonic cleaner...carbon ring

So I borrowed a Hornady sonic cleaner from a guy who had never used it, along with a bottle of their cleaning solution. Been having some seating pressure inconsistencies and wanted to see 1) what the sonic cleaning is all about and 2) get my case necks completely clean and see if the seating pressure evened out.

Got it set up last night, mixed the solution, poured it in the machine and ran a few cycles with solution only, had read somewhere that it was best to do this to remove small amounts of aeration in the water (don't know if if did anything but was no bother to run a couple 7 min cycles).

First I did a test run of some old PPC brass with well over 10 firings on it. After 2 and a half 7min cycles the brass was very clean on the inside, maybe a speck here and there in the body but the necks and bases were perfect. The brass didn't have the high polished sheen but wasn't stained or tainted looking.

Next I had an old brake that had never been cleaned, maybe 600 firings on it, 2 7 min cycles and it was almost like new, a couple tiny specks in the crevices but another cycle would probably finish those off.

So I'm wondering if putting the chamber end of the barrel in the machine and running it would work on the carbon ring that forms at the end of the chamber. My concerns are that the solution might not be good for the steel and would it be effective if only a small portion of the object was submerged and supported by the device.

Does anyone have any experience with these things and the possibilities and limitations of what they might be able to clean?
 
Whole barrel

A friend of mine who works for a company that cleans blinds. They use ultrasonic cleaning baths to do this. He took off the barrel and immersed the whole thing in the bath. It got rid of the carbon ring and no doubt removed any carbon from the rest of the barrel. Not sure what was in the bath. We'll have to wait and see what happens to the barrel. Sometimes it takes time for the full extent of what was done to become evident. Personally I wouldn't have done it.

The size of your tank seems to be the only limiting factor. I'd call the Techs at Brownells for advice. Some have lots of experience in this area.

Take a look at this article by Steve Schmidt: http://www.brownells.com/.aspx/lid=...aning-Clinic-Ultrasonics-The-King-Of-Cleaning

They even offer a testing service that might be free: "If you have questions about different cleaning products or techniques you want us to test, be sure to let me [Steve Schmidt] know at WebBench@Brownells.com."

Sounds like a good deal. :)
 
I say go for it, I definitely would in your position. I can't conceive of any possible negative effect. It may not do anything but it sure can't HURT anything either.

keep us posted

Is there a label of what is in the solution? Jewelers use sonic baths to clean rings and other high end baubles all the time. So what ever solution they use must be fairly benign. I have a very small unit from Harbor freight . They sell the solution in a powdered form separately. Just a water rinse after the cleaning cycle. I do not know if it could be used on barrel steel, but stainless isn't a problem. the interior of the unit is stainless likely 300 series. ( or what ever the current nomenclature is nowadays for non heat treatable stainless)
