I'm doing it right now too... Must be a Sunday thing

Everclear (Pure Grain Alcohol) in a Sonic Jewelry Cleaner. You can get the cleaner at Walmart, Amazon etc.
Run 3 cycles of 3 minutes or so then blow out the attys and place them connector up on a paper towel. If you need one quickly you can read about dry burning your atty. I don't recommend it but many do. My
juice tasted sooty when I tried it.
