Last night I had my first foray into this field. After having used wire wool to start, then a Lyman Tumbler I have moved on to Ultrasonic Cleaning for my brass.

To read about how my first time with it went check out my blog: http://blog.stegough.com/index.php/ultr ... ass-cases/

Anybody here use this method? What do you use for your solution...?

Personally I use Just use water and citric acid to limit any damage to the cases.

How much citric acid do you use? What proportions?

Do you rinse?

I used Citric Acid and water, but then neutralised the acid on the case with Bicarb then rinsed it all off with tap water....

5% solutions of both.

sorry mate, I put in table spoon per litre which seems to work.

I run through as many cycles as needed, the rinse in cold water and dry off as best possible using kitchen towel. Then I leave them to dry or have been know to put them in the oven as it cools down after tea

I find warm water and washing-up liquid does the trick. I've tried adding vinegar but don't really think it's necessary.

I'm 100% an ultrasonic convert.

Do you get white residue on your cases? I do but I'm in a hard water area.

I use the seaweed stuff from Maplin btw.

I got white residue on the first batch of cases because I didn't rinse off the bicarbonate of soda, after that I rinsed every one with fresh tap water. luckily our water doesn't have too many minerals and aside from very sparse water spots, I didn't get any marks on the cases...

Sounds like you need to neutralise the bicarb with some kind of acid. Maybe citric would do it.

Being in God's own country we don't got no limescale here.

Malt vinegar then rinse them in cold water or put them into my rotary with SS pins if i want them subsequently polished.
