Tumbling does the trick! You found that too much Dawn causes bulging. I found that too. I also discovered that vinegar reacted with my colored aquarium gravel, causing bulging too. With a splash of CLR, it cleans a lot off without needing the gravel.
I recommend picking out all the badly corroded ones before dumping them in a counting machine. Don't roll them or try to spend them either. They are junk.
Tumble on!
