Hey Guys,
I have just tried some ultrasonic cleaning and think I might have assed things up.
I had four different batches of the same (308 Lapua) brass that I have just tried to clean using a ultrasonic cleaner.
The first batch was 200 rounds of once fired (large glass jar)
The second was 50 rounds of twice fired (large glass jar)
The third was 100 rounds of third times fired brass (large glass jar)
And the fourth batch, you guessed it was 100 rounds of four times fired brass (large glass jar)
The solutions as stated on the 6mmbr website (http://www.6mmbr.com/ultrasonic.html)
was used.
However as I was doing four different batches I would put a batch in the vinegar solution for 28 min(jar), then put them in a plastic bucket using a strainer to remove the solution without any rinsing, then do the next batch (same method) using the previous batches solution and so on until all four batches were washed in vinegar and set aside.
Once all four were washed in the vinegar I would get the first batch, wash (ultrasonic cleaner in jar) in the B&C solution, then rinse in hot water (no ultrasonic cleaner) then ultrasonic clean with the distilled water (jar again).
Before I rinsed the batches some cases were greenish like engine coolant. After rinsing the green colour was gone.
Have I left the cases to long without rinsing them to remove the vinegar solution?
Some are looking discoloured and rusty.
Should I have not used a glass container and put them directly into the tub giving a better clean and that is why they are this colour?
This is my first attempt and think I went in gun ho and am conserned I have f*#ked my brass irreversibly.

Any knowledgable advice would be appreciated.
