I've saved the information on ultrasonic cleaners, but I'm wondering what kind of medium you use for blasting carb bodies? I assume it's not sand, but I haven't found a reference to the specific material. If Stan doesn't see this, maybe somebody who is a better Googler than I am can find it.
Steve, probably soda blasting. Water soluble for one thing.
Walnut shells are also used as a less aggressive blast media.

Glenn, the goldy color is from buffing with Tripoli and then white rouge on a loose buff. I also do some sanding and wire brushing on the OF's before I buff them out. I bead blast them gently with fine glass bead to start with. The smaller parts go in my vibratory tumbler for a few hours with plastic green pyramid media, then with dry shine for a few more. Then I buff the things like adjuster screws.
I no longer do them the same way i used to. I dont have time. I use very fine glass bead at 150 psi for a quick clean, then i disassemble it, hit the parts with bead, into ultrasonic cleaner one, brass shell casing cleaner, brass ultrasonic two, water bath rinse with brass shell casing cleaner, blow dry and stainless steel wire brush and fine sanding drums, ready for reassembly. I do not like walnut as it disintegrates too quickly and is too slow. I do not buff anything, soda is good way to make a mess. I am 30 ~ 40 carbs behind, i dont have time to waste time, i do plenty of that already.
Would this work??
It will take the tarnish and powder residue from brass casings but won't clean the crud off an old brass carb.
I've had the best luck with the RCBS cleaners for small parts. Bout a hundred bucks at most sporting goods stores.
