Sonic cleaning of brass

[scamp62]

What do you use for a cleaning liquid??

Simple green makes purple HD cleaner and degreaser.
Amazon has it. I think I dilute it 1/3.

I have a Hornady Lock-N-Load ultrasonic cleaner that works well with a solution of 1/2 liter each of white vinegar, tap water (we have pretty neutral water), a squirt of Dawn and a teaspoon of salt. Not always the brightest brass, but it’s squeaky clean - just don’t want to leave it in too long or it discolors.

Vinegar and water mix, set at high heat.
