Cleaned them the night before, too. This is what they looked like after cleaning up some OF's and a Buffalo that had already been through the media blast cabinet, blown clean and looked clean enough to polish. This is kind of disgusting, isn't it?
After bead blast and blow out, I run the parts through the top one, then rinse and run it through the bottom one. Different chemicals.
BTW, I like these little RCBS shell casing cleaners really well. they are a little over $100, one year warranty and every sporting goods store has them. One has been running hours and hours a day for about 3 years and is still doing fine.
Interesting Stan. I just bought my first ultrasonic cleaner and learning the quirks
I bought too big a one when I started using them, couldn't seem to get much done with it. Terry Horlick told me to get one just bigger than the parts you are cleaning and it would work a lot better. He was right. I have a three gallon one that is too big for most of what I do but works great for bigger stuff.
These are great and you can throw your gold and diamond horseshoe ring in it for about 30 seconds and it will come out so sparkly you look like Za Za when you wear it. Leave it longer and the gold turns orange. Ask me how I know that.
What brand ultrasonic machine? I was thinking on getting a Crest brand.
What are the chemicals you use Stan? I have the harbor freight 1 that is the same size as some of the shell cleaners in the gun books. I think I gave 65 for it and bought the 2 year warranty. I use mine for weedeater-chain saw carbs mostly.
RCBS, started here in Oroville by one Fred Huntington, and they still have a good-sized plant employing many here, although the company is now part of a bigger conglomerate.
I have a few ultrasonic cleaners, use them in toy train work, now I guess I'll use them for cleaning carbs too! I got my first one at a church rummage sale, they didn't know what it was! Nice fairly large commercial job, I had to do some rewiring, but parts were/are available!
Would be interested to find out what chemicals you like Stan.
I use RCBS casing cleaner with a dollop of Green Giant and a splash or two of Heet and some lacquer thinner in the first one, the second one just gets RCBS "Casing Shine."
The reason there is Heet in them is because I use Heet - Isopropel alcohol to leak test carbs and after the leak test I dump it in the ultrasonic instead of just throwing it out. I think it helps clean, too.
We have had our RCBS for a couple of years.Bud.
Stan, did you receive my carbs OK? Dave
We use cleaning fluids from this company http://www.kemet.co.uk/products/cleaning/ultrasonic-cleaning-fluids they are very helpful and give free sample testing and reports before purchasing the fluids, which was great for us as we wasn't sure which to use.
I got a Hornady for Christmas. I've used their chemical and also just used water with a couple of drops of dish liquid and a teaspoon of citric acid (Canning section of the grocery store). I couldn't tell much difference in the cleaning efficiency. This was on black powder cartridge brass. I also put a couple of steel gun parts in it with only water and a couple of drops of dish liquid. Didn't want citric acid on the steel. I was careful with that and went very short cycles until I got comfortable it wasn't going to take the patina off the 150 year old parts. Cleaned 'em great. Just had to dry 'em good to prevent rust, then oil 'em good.
